is reported from which satisfactory yields are obtained by the coupling of N-carbobenzoxy amino acids with di- and tripeptide pentachlorophenyl active ester hydrochlorides. This method provides a convenient approach which limits the degree of racemization during the synthesis of N-protected, C-activated peptide units used for the preparation of sequential polypeptides.
