Studies on the Enzymatic Resolution (III): Enzymatic Resolution of DL-Tryptophan

Abstract

To find out a convenient method for the resolution of DL-tryptophan, asymmetric synthesis of acyl L-tryptophan anilides, and asymmetric hydrolysis of DL-tryptophan esters and DL-tryptophan amide were investigated. As a result, the enzymatic hydrolysis of DL-tryptophan amide was found to be an advantageous procedure for the resolution of DL-tryptophan.
