The invention provides a method for producing an optically active hydroxy lactone which comprises reacting under substantially anhydrous conditions and in the presence of an enzyme an ester and a racemic compound represented by the general formula (I):
wherein n is 0 or 1, any one of R¹ and R² is a hydroxy group, and R²=R³=H or R²=R³=CH when R¹ is the hydroxy group, and R¹=R³=H when R² is the hydroxy group to effect a transesterification reaction, and resolving to an optically active alcohol which has R- or S-configuration and the ester of the symmetric alcohol.
本发明提供了一种生产光学活性羟基内酯的方法,该方法包括在基本无
水的条件下和酶的存在下,使酯和通式(I)所代表的外消旋化合物发生反应:
其中n为0或1,R¹和R²中的任一个为羟基,当R¹为羟基时,R²=R³=H或R²=R³=CH,当R²为羟基时,R¹=R³=H,以实现酯交换反应,并解析成具有R-或S-构型的光学活性醇和对称醇的酯。
