    • 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 β-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 β-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 β-position in relation to the carbon atom to which the esterified hydroxyl group bonds.
    • 根据本发明,提供了一种制备光学活性化合物的方法,其特征在于所述方法包括允许相对于与一个碳原子结合的碳原子相对于碳原子的光学异构体的混合物 烯醇酯的酯化羟基在酶的存在下优先水解任一种旋光异构体,并使得由这种水解产生的羰基化合物能够富集其相对于化合物中的任何一种构型的其异构体的比例 使烯醇酯残留未水解以富集其相对于与酯化羟基键合的碳原子相关的碳原子上具有一个构型的异构体的比例。
