4.16. General procedure for the reaction of aldehydes withdiethylzinc in the presence of chiral catalyst General procedure: To the respective catalyst (0.1 mmol), 1 M Et2Zn in n-hexane solution (3 mL, 3 mmol) was added under an argon atmosphere at room temperature. The reaction was stirred for 25 min at room temperature, and benzaldehyde (1 mmol) was then added to the solution, with subsequent stirring at room temperature for a further 20 h. The reaction was quenched with saturated NH4Cl solution(15 mL) and the mixture was extracted with EtOAc (2 x 20 mL). The combined organic phase was washed with H2O (10 mL), dried (Na2SO4) and evaporated under vacuum. The crude secondary alcohols obtained were purified by flash column chromatography (n-hexane/EtOAc = 4/1). The ee and absolute configuration of the resulting material were determined by chiral GC, using a chiral stationary phase (Chirasil-Dex CB column) at 90 °C.33,34 Stage 1: With (1R,2S,3S,8R)-2-azidomethyl-9,9-dimethyl-3-oxa-5-azatricyclo[6.1.1.02,6]decan-4-one in hexane, Time= 0.416667h, T= 20 °C , Inert atmosphere Stage 2: in hexane, Time= 20h, T= 20 °C , Inert atmosphere, Reagent/catalyst Gonda, Tímea; Balázs, Attila; Tóth, Gábor; Fülöp, Ferenc; Szakonyi, Zsolt; Tetrahedron; vol. 73; nb. 18; (2017); p. 2638 2648 View in Reaxys

4.6 General procedure for the catalytic asymmetric addition of Et2Zn to aldehydes General procedure: Ligand 1c (0.188mmol) was dissolved in toluene (2mL) and Et2Zn (2M in toluene, 2.26mmol) was added in one portion after which the reaction was stirred for 45min. at ambient temperature. The mixture was then cooled to −20°C and the aldehyde (1.88mmol) was added as dissolved in toluene (2mL) into the reaction. The resulting mixture was stirred for 24h at −20°C. The reaction was quenched with saturated ammonium chloride (10mL) and extracted with ethyl acetate (3×10mL). The combined organic extracts were dried over Na2SO4 and concentrated. Purification of the crude product was carried out by micro distillation under reduced pressure. The product was subjected to HPLC by using Chiralcel OD-H column and GC by using Supelco η-Dex capillary column to determine the ee values.

4.5 Asymmetric ethylation of arylaldehyde with diethylzinc General procedure: Diethylzinc (1.1ml, 1M solution in hexane) was added to a stirred solution of ligand (0.033mmol) in toluene (1.0ml) under Ar at room temperature. After stirring the resulting reaction mixture at this temperature for 15min, benzaldehyde (0.05ml, 0.55mmol) was added. Stirring was continued for 24h at room temperature. At the end of this period, the reaction mixture was diluted with ethyl acetate (10ml), quenched with a saturated aqueous solution of NH4Cl (10ml), and the two layers were separated. The aqueous layer was extracted with ethyl acetate (2×10ml). The combined organic layers were dried over Na2SO4, concentrated and purified by flash column chromatography on silica gel using hexane–ethyl acetate. 1-Phenyl-1-propanol was obtained in 81percent yield (61mg, 0.446 mmol). Chiral HPLC was used to determine the ee. Other asymmetric reaction using various aldehydes and ligands were examined with the same procedure.

EXAMPLE 33 12.2 mg (2*10-5 moles) of [Ir(PPEI)COD]+ ClO4 - (+) were suspended in 50 ml of isopropanol and oxidized with air for 4 hours. The yellow limpid solution so obtained was degasified for 20 minutes at reflux under a nitrogen stream and then treated with 2.7 ml of a deaerated isopropanol solution of KOH (2 mg of KOH). The solution was preliminarily reduced for 30 minutes in a N2 stream at reflux and then treated with 2.56 ml of deaerated propiophenone. After 60 minutes the reaction was stopped, obtaining a conversion to phenylpropanol (+) of 57.3percent with an e.e. of 30percent. Ratios: [substratum]/[cat.]=1000; [KOH]/[cat.]=1.8.

Synthesis of secondary alcohols General procedure: All racemic alcohols except for the (R,S)-1-phenylethanol were prepared using the following procedure: a mixture of ketone (5 mmol) and sodium borohydride (10 mmol) in anhydrous methanol (50 mL) was stirred at room temperature for 30 min. Next, saturated NaHCO3 (50 mL) and CH2Cl2 (100 mL) were introduced, and the mixture was stirred at room temperature for another 10 min. The organic layer was removed, and the aqueous layer was extracted twice with 25 mL CH2Cl2.

2.3.1. Procedure using [IrCl(cod)]2as an Ir catalyst precursor General procedure: A flask was charged with azolium salt L12 (0.02 mmol, 9.1 mg),Ag2O (0.01 mmol, 2.4 mg) and CH2Cl2(1 mL). After stirring the resulting mixture at room temperature for 2 h in the dark, CH2Cl2 was removed in vacuo. Then, a THF (1 mL) solution of [IrCl(cod)]2(0.01 mmol, 6.9 mg) was added to the reaction vessel. The resulting mixture was stirred at room temperature for an additional 4 h in the dark, filtered through a membrane filter, and evaporated to dry-ness in vacuo. Subsequently, to the resulting flask containing yellow solid of the unpurified IrCl(cod)(NHC) complex, a solution of AgBF4(0.025 mmol, 4.9 mg) in CPME (2 mL) was added, and then stirred at room temperature for 1 h. Finally, propiophenone (0.5 mmol,66 mg) and (EtO)2MeSiH (2.25 mmol, 294 mg) were added to the resulting CPME solution (see Appendix A. Supplementary data fordetails). After stirring at room temperature for 20 h under open-air conditions, K2CO3(2 mg) and MeOH (2 mL) were added. Then, the resulting mixture was stirred at room temperature for 2 h. Afterevaporation of the solvents, the residue obtained was purified bycolumn chromatography on silica gel (Et2O/n-hexane = 3:7) to give(S)-1-phenyl-1-propanol (61 mg, 91percent isolated yield).

In 2-propanol at reflux and in the presence of NaO/'Pr (2 mol percent) the ketones in Table 1 are efficiently reduced via transfer hydrogenation with a S/C ratio up to 20000/1 . The ketones are selected to cover a broad range of structures: alkyl-arylketones 23-27, benzophenone 29 and dialkylketones 28, 30-32. Ketones 27 and 28 having bulky tertBu substituents are reduced with near complete conversion of the substrate. Reduction of C=0 bond of 5-hexen-2-one 30 is entirely chemoselective, without saturation or isomerization of the terminal C=C bond. The use of methyl-benzo[ ?]quinoline or phenyl-benzo[ ?] quinoline ligands allows a fine tuning of catalyst activity and selectivity.

Conditions & References 4 : Enzyme-Catalysed Kinetic Resolution of Chiral Esters General procedure: Preparative enzymatic conversions of racemic chiral esters were performed on a 10 ml scale with 0.25-0.3 mmol substrate and 1-2 ml enzyme preparation (50 U/ml based on p-nitrophenyl butyrate assay) in 50 mM phosphate-buffer pH 7.5. The reaction was stirred in a water bath at 37° C. up to a conversion of 50percent. After addition of the same volume A. dest educts and/or products were extracted as follows: ethylesters were acidified with HCl (aq. 10percent, 10 ml) and afterwards extracted with 4×20 ml diethylether. Methylesters were extracted first using a neutral to slight alkaline pH, afterwards the reaction was acidified to extract the reaction products. Acetylated substrates were extracted with 4×20 ml methylen chloride. In each case the organic phases were pooled, dried with Na2SO4 and afterwards evaporated. Reaction educts and products were separated by chromatography and analysed by NMR, polarimetric and GC-analysis to determine the grade of purity, the degree and sense of optical rotation and the enantiomeric excess.

Step A: Preparation of 3-(3-methoxypheny)-1-phenylpropanol To a solution of benzaldehyde (920 μl, 9 mmol) in dry THF (20 mL) was added slowly a solution of 2-(3-methoxyphenyl) ethylmagnesium bromide prepared from 2-(3-methoxyphenyl) ethyl bromide (2.1 g. 9.77 mmol) and magnesium (300 mg, 12 mmol). The mixture was stirred at room temperature for 1/2 hour then quenched with saturated NH4Cl. The mixture was then extracted into EtOAc, washed with H2O, dried (Na2SO4), filtered and concentrated in vacuo, then purified by silica gel chromatography (30percent EtOAc/Hexane) to provide the desired product as a colorless viscous oil.
