ABSTRACT:
The primary hydroxy group of Corey lactone diols is optically selectively acylated to obtain the desired optically active ester and/or diol. The mixture of Corey lactone diols of formulae (Ia) and (Ib): ##STR1## is reacted with an acylating agent optically selectively in the presence of an enzyme and/or a microorganism thereby to acylate, isolate and purify the primary alcohol.
