General procedure
General procedure: All reactions were performed in a glass flask slurry reactor connected to an O2 tube for atmosphere control and a condenser for reflux condition. A mixture of alcohol (1mmol), Cs2CO3 (0.5mmol) and 2Au/1CuO–ZnO (0.05g) in water was stirred under oxygen atmosphere in a slurry reactor at total reflux condition. Then the catalyst was recovered by filtration, washed two times with 5ml hot EtOAc, and dried for consecutive reaction runs. The filtrate was quenched with 2M HCl aqueous solution, extracted with EtOAc three times and dried over anhydrous MgSO4. Evaporation of the solvent followed by column chromatography on silica gel afforded the pure products (Table3). 93%

3.11:
To a solution of gallic acid (1.00 g, 5.88 mmol) in DMF were added K2CO3 (16.0 g, 0.118 mol), CH3I (11.0 ml, 0.176 mol) and the mixture was stirred under reflux for 1h. The mixture was filtered and the filtrated solvent was evaporated in vacuo. The residue was dissolved in CH2Cl2, and the organic layer was washed with H2O and then dried over MgSO4. The solvent was evaporated in vacuo and the resulting precipitate was purified by silica-gel column chromatography (hexane:AcOEt=4:1) to give benzaldehyde (0.920 g, 4.07 mmol). To a solution of benzaldehyde (0.920 g, 4.07 mmol) in THF was added LiAlH4 (0.300 g, 7.96 mmol) at 0. After being stirred for 1h at room temperature, H2O and 1M NaOH aq. were added to the solution. The mixture was filtered and the organic layer was evaporated in vacuo to yield benzylalcohol (0.680 g, 3.43 mmol). To a solution of benzylalcohol (0.680 g, 3.43 mmol) in CH2Cl2 was added PDC (1.94 g, 5.15 mmol) and the mixture was stirred at room temperature for 5h. The mixture was filtered on celite pad and the solvent was evaporated in vacuo. The residue was purified by silica-gel column chromatography (hexane:AcOEt=4:1) togive benzaldehyde (0.540 g, 2.75 mmol). To a solution of benzaldehyde (0.540 g, 2.75 mmol) in THF were added ethyldiethylphosphonoacetate (1.10 ml, 5.50 mmol) and NaH (0.120 g, 3.03 mmol) at 0. The mixture was warmed to room temperature and stirred for 1h. After AcOEt and H2O were added to the solution, the organic layer was evaporated in vacuo and the crude was purified by silica-gel column chromatography (hexane:AcOEt=4:1) to give unsaturated ethyl ester (0.540 g, 2.03 mmol). To a solution of unsaturated ethyl ester (0.540 g, 2.03 mmol) in MeOH was added LiOH-H2O (0.920 g, 21.8 mmol). After being stirred under reflux for 2h, 1M HCl aq. and AcOEt were added to the mixture. The organic layer was washed with H2O and brine. The solvent was evaporated in vacuo to yield unsaturated carboxyl acid (0.417 g, 1.75 mmol, 30 percent in 5 steps) as a white powder.

5:Example 5: Procedure for 3,4,5-Trimethoxybenzaldehyde :
Example 5: Procedure for 3,4,5-Trimethoxybenzaldehyde :Paraformaldehyde (45 g), 30percent hydrochloric acid (182 g) and 1,2,3-trimethoxybenzene (168 g) and toluene (1680 g) were charged into a 3 litre glass reactor. Hydrogenchloride gas was passed rapidly through the reaction medium at about 10°C till the corresponding benzyl chloride (formula VII) was ~ 90percent by GC analysis. The aqueous portion was drained off and the organic portion was digested with hexamine (168 g) at about 90 °C till the benzyl chloride (VII) content was less than 1.0 percent by GC analysis. 50percent aqueous acetic acid (360 g) was added to the resulting hexamine complex and the reaction mass was digested at about 80°C for 6 to 8 hours. The aqueous portion was drained off and the organic portion was concentrated and the crude product was distilled to obtain 3,4,5-Trimethoxybenzaldehyde of purity greater than 95percent by GC analysis (130 g).

4.3. (R)-(-)-Acetoxy-3,4,5-trimethoxyphenylacetonitrile (R)-1
Racemic acetoxy-3,4,5-trimethoxyphenylacetonitrile (3.18 g, 12 mmol) was dissolved in toluene (12 mL) and 0.1 M pH 7 potassium phosphate buffer (48 mL) was added followed by C. antarctica A (1.18 g, 37percent w/w). The mixture was shaken and the pH was maintained at 7 via automatic addition of 1 M NaOH using a pH stat. After 22.5 h the reaction mixture was sonicated for 15 min then filtered through Celite.(R).. The Celite.(R). pad was washed with diethyl ether (3 .x. 125 mL), the filtrate was transferred to a separating funnel and, without shaking, the organic phase was removed, dried and concentrated in vacuo to afford the crude product mixture as an oil (2.77 g). This mixture was subjected to column chromatography (ether/hexane, 7:3) to provide a 1:1 mixture of the unhydrolysed ester and the aldehyde (2.36 g).

EXAMPLE 2 50g of syringealdehyde (0.275 mol) 40g of sodium carbonate (0.38 mol) and 53.4g of dimethyl sulfate (0.42 mol) were placed in a round-bottom flask and heated substantially as in Example 1. When the temperature reached 75° C the reaction mixture became fluid but after 30 minutes at a temperature between 80° and 87° it began to thicken again. 30 ml. of water was then added dropwise while the temperature was maintained for 1.2 hours. On completion of the reaction 250 ml of hot water was added to the mixture. Then the mixture was cooled, the solidified organic material separated by filtration, washed with water and vacuum dried. The yield of 3,4,5-trimethoxybenzaldehyde was 99.6percent with about 0.4percent syringealdehyde remaining.

4:EXAMPLE 4
EXAMPLE 4 25.0g syringealdehyde (0.137 mol), 26.6g of dimethyl sulfate (0.211 mol), and 27.7 g. of potassium carbonate (0.201 mol) were heated with stirring as in Example 1. When the temperature reached 45° C the mixture became fluid and carbon dioxide was given off. The temperature was slowly increased to 75° C and held at this value for 1 hour. Addition of water, acidification, and benzene extraction gave a quantitative yield of 3,4,5-trimethoxybenzaldehyde which contained no detectable syringealdehyde or other impurities as determined by g.l.c. analysis.
