Abstract

Production of optically pure N-acyl-D-phenylalanine ester by reacting a racemic mixture of N-acyl-D,L-phenylalanine ester with a proteolytic enzyme and separating the resulting N-acyl-D-phenylalanine ester from the solution with subsequent removal of the N-acyl and ester groups to provide D-phenylalanine.
