Procedure: To a solution of N-trityl-L-valine (5.5 g, 15.2 mmole), 2-allyl-1,3-propandiol (4.4 g, 38 mmol), N,N-dimethylamino pyridine (183 mg, 1.5 mmol) in dichloromethane (120 ml) was added DCC (3.5 g, 16.7 mmol). The reaction was kept under reflux overnight. After filtration through Celite, the organic phase was washed with sodium hydrogen carbonate aqueous solution and dried. Silica gel column chromatography gave 4.6 g intermediate 1-O—(N-trityl-L-valyl)-2-allyl-1,3-propandiol. under reflux overnight After filtration through Celite the organic phase was washed with sodium hydrogen carbonate aqueous solution dried

Procedure: A mixture of 2-allyl-1,3-propanediol (0.116 g, 1 mmol), whole cells containing C. oxydans (0.1 g) and vinyl acetate saturated water (20 mL) was shaken at 30° C. and 300 RPM for 48 hours. The optically active monoacetate of 2-allyl-1,3-propanediol was obtained in 85% yield. Structure determination was done by nuclear magnetic resonance. containing C
