Abstract

Summary From the treatment of a series of N-carboallyloxyderivatives of a-amino acids with phenylhydrazine in the presence of papain, the crystalline phenyl hydrazides have been obtained in every case. While the carboallyloxy derivatives of L-amino acids yield the corresponding L-phenylhydrazides the derivatives of DL-amino acids do not invariably yield the optically pure L-phenylhydrazide. Under the conditions of the experiments, the D- ...
