Oxidation of tetrahydrofuran
The oxidation of tetrahydrofuran with the iron complex (1) gave no appreciable yieldof α-butyro-lactone with O2 and t-BuOOH. However, the 28.8 percent yield was noted with the combination of 1/H2O2/ethyl acetateafter 24 h, which decreases considerably with time. Comparedto iron complex (1), ruthenium complex (2) gave α-butyrolactone with only t-BuOOH but in poor yield (0.7-2.2 percent) (Table-3). 11%

A:Catalytic runs; Table A. Oxidation of THF under various conditions
In a typical catalytic run, 0.1 mmol of the catalyst precursor was dissolved in 30 ml of dry THF and stirred under atmospheres of [OS,] [OS/CO] (1 [: 1)] and [02/C02] (1 [: 1)] respectively, which were supplied by balloon. The control runs under Ar, CO and C02 were carried out in sealed Schlenk flasks under a pressure of 0. [5] bar. The reactions were monitored by IR spectroscopy and the amounts of y-butyrolactone formed were derived from reference calibration (area for the v-CO band at 1780 [CM~1).] A rough quantitative approximation of the sum of all other products was obtained by reference to [PROPYLFORMATE] calibration (area for the v-CO band at 1726 [CM-APOS;,] relevant for all formed CO compounds other than y-butyrolactone). Fractional distillation of the reaction mixture of a typical 3 + [OS] run allowed us to isolate the pure products y- butyrolactone, succinic acid and [PROPYLFORMATE] as well as to quantify the sum of all other products. The formate acetal 6 [10] and others were detected in the mother solution and mixed fractions (NMR) but were not isolated. The organic compounds were identified by comparison of spectral data with literature results and/or authentic samples.

A stock solution of KHSO5 was prepared in degassed D20 under N2. Catalyst (e.g., Co-dppe) was added to each reaction tube. The tubes were then evacuated under vacuum and refilled with N2 several times. 400 jtL of d5-ac- etone was added to each tube followed by the appropriate substrate. Reactions were initiated by the addition of 100 pL of KHSO5 stock solution. Reactions were monitored for 3 or 15 hrs depending on the substrate. The reactions were quenched by addition of a stock solution of d4-sodium trimethylsilyl propionate (NMR internal standard) and d5-dim- ethylsulfoxide (oxidant quench). The reactions stirred another 15 mm and then were filtered into NMR tubes. The reactions were quantified by NMR. (Control reactions were performed without catalyst and in each case the substrate conversion is >5percent)10209] For most of the substrates selective oxidation to a single product was observed. The catalyst system was able to oxidize unactivated alkanes to a single product but in low yield. Oxidation of 1 -butanol illustrates the difference the catalyst and simple cobalt salts. The catalyst selectively oxidizes butanol to
butyric acid whereas the CoOl) salts tested were highly unselective, affording several different products.

Gas-phase hydrogenation of MA to GBL was carried outin a tubular quartz fixed-bed reactor (inside diameter = 13 mm,length = 650 mm) at atmospheric pressure. 6 mL of catalyst (height = 45 mm) was packed in the constant temperature part of the reactor, and then 15 mL of quartz sand pre treated at 600 °C inair was loaded above the catalyst for the complete gasification ofthe raw material (20 wt.percent MA dissolved in GBL). Prior to the test, the as-prepared catalyst was activated by 60 mL min−1of 5 vol.percent H2/N2at 300 °C for 6 h (designated as the fresh catalyst). Then the temperature was lowered to 220 °C, and 27.5 N mL min−1 of pure H2 and 0.2 h−1 (liquid hourly space velocity, LHSV) of raw material, were fed into the reactor. The products
were sampled using the conical beakers cooled by an ice-bath at intervals of 1 h and analyzed by Perkin-Elmer Clarus 500 gas chromatograph equipped with a FID detector and a SE-54 capillary column (25 m × 0.32 mm × 1.0 m). The temperatures of the injector and detector were 220 °C, and the temperature of the column oven was kept at 100 °C for 1 min and then increased programmedly to 120 °C at the rate of 5C min−1.

2.3. General Procedures of BV oxidation
General procedure: Ionic hybrid (0.5 mmol) and ketone (10 mmol) was added toa 25mL flask equipped with a condenser and magnetic stirrer. The reaction was started after the addition of H2O2 aqueous (35 wt.percent, 25mmol)in dropwise at 50 °C under vigorous stirring. The progress of the reaction was monitored by TLC (hexane/ethyl acetate=4/1). After the completion,the mixture was extracted with diethyl ether (3 × 15 mL).The combined organic layer was washed with aqueous of NaHCO3(3 × 15 mL) and water (3 × 15 mL), then dried over anhydrous MgSO4, filtered, and concentrated under vacuum to afford the crude product. The crude product was purified by column chromatography using hexane–ethyl acetate 4:1 (V/V) as eluent. The obtained product was identified by comparing TLC, 1H NMR and IR spectra data with authentic sample. The catalyst was recovered by washed with diethylether (3 × 10 mL), and then dried under vacuum at 80 °C over 8 h.Oxidant efficiency is determined by iodometric titration methods described in literature [25]. The results revealed that the amount of H2O2 present at the reaction endpoint was 2–3 mmol. 85%

13:General Baeyer-Villiger procedure
General procedure: To a flame dried crimp top vial under argon, KHCO3 (80mg, 0.8mmol, 0.2equiv) was weighed, followed by urea hydrogen peroxide (564mg, 24mmol, 6.0equiv). The ketone (4.0mmol, 1.0equiv) was added at this stage if it was a solid. The vial was then sealed and evacuated, followed by backfilling with argon (repeated three times). Afterward, the solvent (8.0mL), benzonitrile (2.48mL, 24mmol, 6.0equiv) and, if it was a liquid, the ketone (4.0mmol, 1.0equiv), were added via syringe. The reaction was allowed to run for the specified time at 50°C, after which it was cooled down to room temperature. The pressure was released with a needle, then the vial was opened. The mixture was diluted with CH2Cl2 (40mL) and water (20mL). The layers were separated and the resulting aqueous solution was extracted with CH2Cl2 (2×40mL). The combined organic layers were dried (MgSO4), concentrated in vacuo, and the crude product was subjected to flash chromatography on silica gel (5:1 petroleum ether:EtOAc) to afford the corresponding product(s). 62%

General procedure: In typical conditions, Re catalysts were used as stock solutions (for this, 10.0 mg of the compound 1–10 were dissolved in 2.00 mL of 1,2-dichloroethane, 1,2 DCE). The required amount of this stock solution for the desired oxidant/catalyst molar ratio (1000:1) was transferred to a second flask containing 3.00 mL of 1,2-dichloroethane. 1.7 mmol of H2O2 as a 30percent aqueous solution (102 μL) and 1.7 mmol of substrate were then added, and the reaction solution was stirred for 6 h at the desired temperature (typically 70 °C) and normal pressure (dinitrogen atmosphere). Then, 120 μL of cycloheptanone (internal standard) and 10.00 mL of diethyl ether (to extract the substrate and the organic products from the reaction mixture) were added. The obtained mixture was stirred during 10 min and then a sample (1 μL) was taken from the organic phase and analysed by GC using the internal standard method. Blank tests indicate that no oxidation takes place in the absence of the Re catalyst or the oxidant.

2.5 Biotransformations using whole cells and crude cell extract
General procedure: Whole-cell biotransformations were performed using both growing and resting cells. For growing cells, 2 ml TB medium in a 15 ml Falcon tube was inoculated with a pre-culture of E. coli BL21-CodonPlus(DE3)-RP cells containing the recombinant plasmid with the BVMO gene. The cells were grown for 3 h at 30 °C and with shaking at 150 rpm. Immediately after adding IPTG, the biotransformation reaction was initiated by adding the substrate to a final concentration of 5 mM. To boost the regeneration of NADPH, glucose (25 mM) was also added at the moment of induction. Biotransformations were carried out for 16 h at 15 °C and at a shake rate of 150 rpm. The level of conversion was measured by comparing E. coli BL21-CodonPlus(DE3)RP expressing BVMO3 with cells from the same E. coli strain carrying pET-22b(+) without the BVMO3 gene, that served also as a blank for side reactions.

2.7 General procedure for the chemoenzymatic synthesis of lactones 2a–l using CAL-B, UHP and EtOAc
General procedure: Over a solution of the corresponding cyclobutanone 1a–l (0.25 mmol) in EtOAc (379 μL, 30.0 mmol), complex urea-hydrogen peroxide (UHP, 35 mg, 0.38 mmol) and CAL-B (12.5 mg) were added. The suspension was shaken for 20 h at 30 °C and 250 rpm, then an aliquot was analyzed by GC. The reaction was left shaken until complete conversion was reached, then water was added (2 mL) and the enzyme filtered off. The solution was extracted with EtOAc (3× 5 mL) and the organic phases combined and washed with water (2× 5 mL) and brine (5 mL). The resulting organic phase was dried over Na2SO4, filtered and the solvent was evaporated under reduced pressure to obtain the corresponding lactones 2a–l (51–99percent isolated yield). For fluorinated lactone 2k a column chromatography on silica gel (30percent EtOAc/hexane) was necessary, as the reaction did not lead to complete conversion.

4.4.1. General procedure for the BVMO-catalyzed oxidation of prochiralcyclobutanones 1a-j, m-v.
General procedure: In a typical experiment carried out in 1.5 mL tubes (total volume of 500 μL), the substrate 1a-j, m-v (10 mM) was dissolved in methanol (5 μL, 1percent v/v) and KPi buffer (100 mM, pH 9.0, 482 μL), containing glucose (20 mM), glucose dehydrogenase (GDH-105, 10 U, from stock solution of 1.275 U/μL), NADPH (0.2 mM, from a 20 mM stock solution) and the corresponding Baeyere-Villiger monooxygenase (2 mg). The mixture was shaken at 250 rpm at 30 °C for 24 h. The reaction was stopped by extracting with diethyl ether (2x400 μL) and centrifugedat 13,000 rpm in order to separate both phases and pellet the suspended protein. The organic phases were combined, dried over anhydrous sodium sulfate and analyzed by GC in order to determine the conversion values. Then, the solvent in GC samples was evaporated with a continuous flow of nitrogen, the residue redissolved in a mixture of hexane:ethanol 90:10 and the new sample filtered and analyzed by HPLC, leading to the measurement of the enantiomeric excess of the lactones. Control experiments in the absence of enzyme were performed for all substrates, not observing any reaction product after similar periods of time (Tables S1-S19).

2.3 B–V Oxidation of Ketones with H2O2
General procedure: SnO2/GO nanocomposites (0.05 g) and ketones (1.0 mmol) were mixed in 1,2-dichloroethane (15 mL) under vigorously stirring. H2O2 (30 wtpercent, 2.0 mmol) was then added dropwise at 90 °C. The reaction progress was monitored by GC. After the reaction, catalyst was separated by centrifugation. The liquid reaction mixture was extracted by ethyl ether and then quantitatively analyzed by a 6890 N gas chromatograph (Agilent Co.) equipped with the capillary column (HP19091G-B213, 30 m x 0.32 mm x 0.25 μm). The recovered catalyst was washed with ethanol and distilled water repeatedly, and dried at 40 °C overnight for reused.

16.2:16-2) Production of Gamma-Butyrolactone
The carrier gas, nitrogen, was flowed downward from the upper part of the fixed-bed flow reactor having the Cu—ZnO—Al2O3—ZrO3 catalyst layer at a flow rate of 30 ml/min under atmospheric pressure. 1,4-butanediol was supplied together with the nitrogen gas, vaporized in the vaporizing layer and supplied to the catalyst layer. Herein, the temperature of the vaporizing layer and the catalyst layer was 240° C. Upon the increase of LHSV (liquid hourly space velocity) to 0.5 h−1 of 1,4-butanediol, the maximum yield of gamma-butyrolactone were 97.9percent. 96%

Conversion of BDO to GLB is done in the gas phase at elevated temperature and pressure. BDO is supplied as a liquid and is vaporized prior to coming into contact with the catalyst. In one embodiment, the temperature is from about 150 to about 300° C. In another embodiment, the temperature is from about 175 to about 275° C. In yet another embodiment, the temperature is from about 185 to about 250° C. In one embodiment, the conversion of BDO to GLB is performed by contacting the inventive catalyst with either neat BDO or a mixture containing BDO in the gas or liquid phase. In another embodiment, the conversion of BDO to GLB is performed by passing neat BDO or a mixture of BDO in the gas or liquid phase at a constant or variable rate.Similarly, the inventive catalyst can perform over a range of pressure. In one embodiment, the pressure is from about 10 to about 150 psig. In one embodiment, the pressure is from about 20 to about 200 psig. In yet another embodiment, the pressure is from about 30 to about 90 psig. The rate of BDO supplied to the catalyst can be described in terms of liquid hourly space velocity, which is defined as the mass of BDO supplied per unit mass of catalyst per hour. In one embodiment, LHSV is from about 0.1 to about 3 hr-1. In another embodiment, LHSV is from about 0.2 to about 2 hr-1. In yet another embodiment, LHSV is from about 0.4 to about 1.5 hr-1.The conversion of BDO to GLB is a dehydrogenation reaction that produces one mole of GLB and two moles of hydrogen gas per mole of BDO. However, competing side reactions are also catalyzed at low rates. The product stream may contain in addition to GLB, tetrahydrofuran (THF), water, acetal, butanol, and butyric acid among other components. In one embodiment, the conversion of BDO to GLB is over about 90percent. In another embodiment, the conversion of BDO to GLB is over about 95percent. In yet another embodiment, the conversion of BDO to GLB is over 99percent.The dehydrogenation reaction of BDO to GLB does not require hydrogen to proceed. Nevertheless, hydrogen is typically included in the gas phase passed over the catalyst in order to keep metal sites in the catalyst reduced. The rate of hydrogen supplied can be described in terms of gas hourly space velocity (GHSV), which is mass of hydrogen per unit mass of catalyst per hour. In one embodiment, GHSV for hydrogen gas is from about 500 to about 2500 hr-1. In another embodiment, GHSV for hydrogen gas is from about 750 to about 2000 hr-1. In yet another embodiment, GHSV for hydrogen gas is from about 1000 to 1500 hr-1.

5.2 General procedure for catalytic oxidation of diols to lactones using TetMe-IA via in situ-generated TetMe-IBX
General procedure: In a typical experiment, a round bottom flask containing 4–6mL of acetonitrile/water mixture (1:1) was charged with 0.5–1.0mmol of the diol, 5molpercent of TetMe-IA, and oxone (2equiv). The resulting mixture was stirred at rt for benzylic diols and at 45°C for aliphatic diols. At the end of the reaction, as judged from TLC analysis, little water was added to dissolve the inorganic salts, and the organic matter was extracted with EtOAc at least two times. The combined extract was dried over anhydrous Na2SO4, concentrated in vacuo to obtain the crude product, which was subjected to silica-gel column chromatography using ethyl acetate/pet ether to isolate the pure product. 96 %Chromat.

Examples 1 -6 below were carried out using pure 1 ,4-butynediol as 40percent strength by weight aqueous solution at atmospheric pressure. The butynediol solution was pumped continuously into an externally heated tube (diameter 2.7 cm). The tube was charged with glass rings (30 ml) in the upper region. This zone served as vaporization section in which 1 ,4-butynediol/water and hydrogen (300 liter/h) were heated and passed in gaseous form into a second zone in the reactor tube in which the catalyst was located (20 ml). After the reactor tube, the gaseous reactor output was cooled to about 20°C and product which condensed out was collected. The offgas was passed through a cold trap at -78°C and further product was condensed out in this way. The two condensates were combined for the purposes of analysis. The catalysts were activated in a stream of hydrogen before the reaction. The results are shown in table 1

Hydrogenation of succinic anhydride was conducted ina 150 mL high-pressure batch reactor with a magnetic stirrer.The detailed reaction procedure has been previouslydescribed.28 Before the reaction, 0.3 g of the prepared catalystwas reduced under hydrogen gas (ultra high purity,>99.999percent) at 20 bar and 573 K for 2 h (RuNPs/SiO2-300R). After the catalyst reduction, the reaction vesselwas charged with 0.5 g of succinic anhydride and 50 mLof 1,4-dioxane. The remaining air was removed by purging the reactor with hydrogen gas, and the pressure was increased to 10 bar with H2. Once the reactor was heated to and maintained the reaction temperature, the pressure was raised to 50 bar with gaseous H2, and the reactionmixture was stirred at 750 rpm for 6 h. To follow theprogress of the reaction, approximately 0.3 mL of liquid samples were collected through the sampling line, which was connected to the bottom of reaction vessel. During the sampling procedure, the reaction pressure was maintained by continuously introducing hydrogen gas from the high-pressure gas reservoir.

1:Example 1
succinic acid 5.9 g (11.8 wtpercent), 5.0 g (Ru : 400 mass ppm) ofsolution obtained by dissolving ruthenium complex having trioctyl phosphine asligand in triglyme and 39.1g triglyme as solvent were charged into an autoclave(material: SUS 316) of 100ml capacity. Nitrogen compound concentration in thereaction mixture was less than 1 mass ppm.[0072]After placing a magnetic stirrer inside the autoclave, theinside of the system was sufficiently replaced with hydrogen. The temperaturewas elevated while stirring using magnetic stirrer, when the inner temperature ofthe autoclave was reached to 205 ° C, hydrogen was inspissated to make the internalpressure to be 0.9 MPa · G (gauge pressure). Taking that time as the reaction startingtime, then hydrogenation reaction was carried out for 2 hours.After completion of the reaction, part of the resultingreaction solution was taken, and as a result of analysis by gas chromatography,the yield of gamma-butyrolactone was 29.6percent. The reaction results are shown inTable 2.

R; S; T; U; V; W; X; Y:Examples 19-27
[0057] Various slurry samples containing used Cat-A catalyst (with nominally 1percent Ru, 6percent Re) taken during operation and after shutdown from a continuous reactor are listed in Table 3. Prior to activity measurement, Comparative Examples R-Y were prepared by simply drying the slurry overnight in a vacuum oven with N2 purge. This treatment only removed water and volatile components, such as THF. Any foulants, such as waxes and other high boiling compounds remained on the catalyst. [0058] Examples 19-27 were prepared wherein the slurry was extracted with THF under reflux and then filtered and dried. First the slurry sample, (normally 50 g of slurry) of about 20percent solids was filtered in a Millipore funnel filter with 0.2 micrometer nylon membrane filter under vacuum (180 mm Hg) to about 50percent solids. This is a slow process (overnight) as the filter cake is very sticky. Then the filter cake was transferred to a 500 ml round bottom flask and mixed with 5 parts of THF (based on 1 part by weight of original slurry). While stirring with a magnetic stirrer, the mixture was heated under reflux for 2 hours at about 66° C. The slurry was then filtered (same type of filter as above) and the resulting cake was dried at 110° C. in a vacuum oven for at least 6 hours. [0059] All resulting samples were tested in the 300-cc batch hydrogenation reactor with pure H2 on a 7percent SAC solution at 2000 psi, 250° C. and 700 RPM. The rate of conversion of SAC to GBL and by-products was measured and reported as STY in Table 3. In the case of the Comparative Examples, the STY was corrected for the real weight of catalyst, which excluded the weight of the organics remaining in the sample after drying. Also, the STY of the Comparative Examples was corrected by subtracting the STY obtained from runs using catalyst and water.

Hydrogenation of succinic acid to BDO
Liquid-phase hydrogenation of succinic acid to BDO was con-ducted in a stainless steel autoclave reactor with a volume of200 ml. Prior to the reaction, the catalysts were reduced using anex situ reduction system at 500C for 4 h with a heating rate of5C/min under 5percent H2/N2flow (50 ml/min). In order to avoid airexposure, reduced catalyst (0.1 g), succinic acid (0.25 g), and 1,4dioxane (50 ml, an inert aprotic solvent) were charged into thereactor in an argon atmosphere glove box. The closed reactor filledwith argon was then mounted to the autoclave chamber as quicklyas possible. After purging the reactor with nitrogen, it was pressur-ized up to 50 bar using hydrogen. The sealed autoclave was heatedto the reaction temperature (200C), and then pressurized up to80 bar using hydrogen. Catalytic reaction was conducted with con-stant stirring (700 rpm) for 7 h. After the reaction, the reactor wascooled to room temperature and depressurized. Reaction productswere analyzed with a gas chromatograph (Younglin, ACME-6100)equipped with a flame ionization detector (FID). Conversion ofsuccinic acid, selectivity for product, and yield for product werecalculated according to the following equations.

The resulting mixture was filtered through a pad of filter aid, washed with brine, dried over sodium sulfate and evaporated to yield the tetrahydrofuranone (mixture of Z- and E-isomers in 4:1 ratio) as a pale yellow oil (23.4 g, 82percent). The oil solidified on standing at room temperature overnight. Crystallisation from dichloromethane/light petroleum (60-80° C.) gave an analytically pure sample of the Z-isomer. m p. 79° C. νmax3094, 3027, 2947, 1799, 1634, 1393, 1289, 1114, 949, 838, 747, 718, 660 cm-1. λmax279 nm (ε 4938).

The initial charge was 672 mg (2.6 mmol) of Rh(CO)2acac, 2.25 g (22.3 mmol) of triethylamine and 32.8 g (1.8 mol) of water in 400 ml of dioxane. 8.2 l (0.31 mol) of acetylene were injected at room temperature with stirring to a pressure of 3.6 bar. The pressure was then raised to 200 bar with carbon monoxide. The reaction batch was heated to 120° C., raising the pressure to 248 bar, and subsequently stirred for 2 h. After cooling and reactor decompression, a sample was taken and analyzed by gas chromatography using the technique of the internal standard. Based on the amount of acetylene used, 59percent of 2(5H)-furanone and 24percent of butyrolactone had formed. 50 bar of hydrogen were then injected at room temperature and the reaction batch heated to 200° C. in the autoclave, raising the pressure to 89 bar. The pressure was then raised to 200 bar with hydrogen, which was followed by 1 h of stirring. After cooling and autoclave decompression the autoclave's effluent was filtered. The filtrate was found to contain only 1percent of the rhodium used. The solid filter residue was reusable as catalyst. Following a distillative workup, butyrolactone was isolated in a yield of 81percent, based on the amount of acetylene used.

Example 2 was repeated, except that the hydrogenation reaction effluent was centrifuged. The centrifugate was worked up by distillation. The solid removed was introduced as an initial charge in 400 ml of dioxane and admixed with 2.25 g (22.3 mmol) of triethylamine and 32.8 g (1.8 mol) of water. 8.2 l (0.31 mol) of acetylene were injected at room temperature with stirring to a pressure of 3.6 bar.

Example 4 illustrates that the catalysis may be performed on a continuous basis. The continuous reactor consisted of an 800 ml Hastelloy Reactor equipped with a Parr Magana drive, gas induction stirrer, baffles and thermowell. Hydrogen (stripping gas) was supplied to the reactor via a Bronkhorst mass thermal flow controller. Nitrogen was regulated down to the desired pressure and supplied to the reactor, when required via a needle valve. 30wtpercent maleic acid solution and deionised water were supplied to the reactor via two concept PUIII constametric pumps. During operation the maleic acid solution was added at a constant rate whilst the deionised water was added only to maintain the level in the reactor. The level in the reactor was monitored by the difference in temperature was then processed using a Moore's 351 controller to drive the deionised water constametric pump. Excess gas to that required in the reaction was added and the excess removed with the volatile products via a heated transfer line. The volatile products condensed in a condenser and were collected in a catch pot. The excess gas was vented through a backpressure regulator. Ruthenium (III) acetylacetonate (0. 91mmols 0.3606g) and tris-l, l, l- (diphenyl- phosphinomethyl) ethane (l. lmmols, 0.7081g), 156.9 were transferred into the reactor. This was sealed, purged with nitrogen before being pressurised to 900psig with nitrogen and this was set as the set point for the back pressure regulator, the stirrer started at 1000rpm and the reactor was heated to 200°C. Once 200° was reached the reactor was left for 30 minutes. 150g of 30wtpercent maleic acid solution was pumped into the reactor and the water pump was turned on to maintain the level in the reactor and the hydrogen flow started at 100NLPH. After a further hour the temperature of the reactor was increased to 250°C. Maleic acid solution was fed into the reactor at an initial rate of 0. 5mls/minute. After 228 hours on line a total of 7126g of maleic acid and water had been fed and 6739g of product recovered giving an overall mass balance of 95percent. This was bulked and analysed, the water and organic analysis was determined using an HP gas chromatograph equipped with a micro TCD (wtpercent) water (89.17), propanol (0.17), tetrahydrofuran (4.33), propionic acid (0.52) ; y-butyrolactone (5.79) others (0.02), giving an overall molar selectivity to tetrahydrofuran of 34percent, and to y-butyrolactone of 59percent.

Step b. This intermediate (0.075 g, 0.3 mmol) was heated with triphosgene (0.300 g, 1 mmol) in DCM (2 mL) to 80° C. in a sealed vial for 2 hrs. It was then cooled to rt, poured into water and extracted with EtOAc. The organic layer was separated, washed with brine, dried with anhydrous Na2SO4, concentrated by rotary evaporation and purified by flash chromatography on silica gel with a gradient elution of 30-70percent EtOAc/hexanes to afford the corresponding oxolidinone as a white solid (0.036 g, 43percent).

Synthesis of 4-bromo-3-butyl-5-(dibromomethylene)-2-tetrahydrofuranone
Synthesis of 4-bromo-3-butyl-5-(dibromomethylene)-2-tetrahydrofuranone Phosphorus pentoxide (10.0 g) was added with stirring to a solution of 2-(1,3,3-tribromo-2-oxopropyl)hexanoic acid (7.7 g, 0.11 mol) in dry dichloromethane (150 ml). The mixture was heated at reflux with stirring for 2 h, and cooled to room temperature.
The resulting mixture was filtered through a pad of filter aid, washed with brine, dried over sodium sulfate and evaporated to yield the tetrahydrofuranone as a pale brown oil (7.0 g, 82percent) that solidified on standing at 4° C. overnight. νmax2958, 2930, 2871, 1820, 1782, 1638, 1455, 1127, 1086, 965, 849, 757, 718 cm-1. 1H n.m.r. δ (CDCl3) 0.93, t, J 6.7 Hz, (H4')3; 1.37-1.81, m, (H3')2-(H1')2; 3.22, t, J 7.5 Hz, H3; 4.79, s, H4. 13C n.m.r. δ (CDCl3): 14.1, C4'; 22.5, C3'; 28.9, C1'; 31.6, C2'; 43.6, C4; 53.7, C3; 76.5, 5-CBr2; 149.8, C5; 172.5, C2.

Reference Example 1Experiments on the Direct Catalytic Hydrogenation of Succinic Salts to THFFor comparative purposes, various salts of succinic acid were subjected to a homogeneous or heterogeneous hydrogenation. Either no reaction (disodium salt) or the formation of various hydrogenation products, such as BDO, GBL or pyrrolidone, is observed, but not the formation of the desired THF product.; Heterogeneous hydrogenation conditions: 3percent Sn/7percent Pt on C, 120° C., 200 bar H2, 24 h.; (b)The monosodium salt can be regarded as a 50:50 mixture of diacid and disodium salt. Only the diacid could in butanediol BDO and GBL. No conversion of a sodium carboxylate was observed. A
