Method for Preparing Optically Active Compound

摘要

According to the present invention, there is provided a method for preparing an optically active compound, characterized in that said method comprises permitting a mixture of optical isomers relative to the carbon atom in the beta-position in relation to the carbon atom bound to an esterified hydroxy group of an enol ester to hydrolyse either one optical isomer preferentially in the presence of an enzyme and allowing the carbonyl compound resulting from such hydrolysis to enrich the proportion of its isomer having either one configuration in the beta-position in relation to the carbonyl group or allowing the enol ester left non-hydrolyzed to enrich the proportion of its isomer having either one configuration on the carbon atom in the beta-position in relation to the carbon atom to which the esterified hydroxyl group bonds.
