Reaction Conditions

Reaction Steps

A mixture of ethyl 2-(1-acetoxyethyl)acrylate (35.65 g) and "Lipase P" (8.88 g) in pH 7.0 phosphate buffer (0.1M) (2.8 l) was stirred at 37° C. for 72 hours. The whole mixture was extracted with ethyl acetate, and the combined extracts were dried. After removal at the solvent from the solution in vacuo, the crude product was purified by column-chromatography on silica gel (eluent : a mixture of hexane and ethyl acetate, 2:1) to give ethyl 2-[(1R)-1-hydroxyethyl]acrylate (11.40 g).
