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