The present invention relates to a process for producing an optically active 2-substituent-oxy-3-(4-substituent-oxyphenyl)propionic acid derivative which comprises stereoselectively reducing an 2-oxo-3-(4-substituent-oxyphenyl)propionic acid by an enzyme and subjecting the thus-obtained optically active 2-hydroxy-3-(4-substituent-oxyphenyl)propionic acid to esterification of the carboxyl group according to need, then to alkylation of the hydroxyl group and, if necessary, to deprotection of an ether type protective group. The present invention may make it possible to produce an optically active 2-substituent-oxy-3-(4-substituent-oxyphenyl)propionic acid derivative, which is useful as intermediates for the synthesis of medicinal compounds, efficiently, in a simple and easy manner, and commercially advantageously.
