ABSTRACT:
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): ##STR1## wherein n is 0 or 1, any one of R.sup.1 and R.sup.2 is a hydroxy group, and R.sup.2 =R.sup.3 =H or R.sup.2 =R.sup.3 =CH.sub.3 when R.sup.1 is the hydroxy group, and R.sup.1 =R.sup.3 =H when R.sup.2 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.
