series of dipeptides and tripeptides were prepared via an activation–coupling method involving the in situ formation of a p-nitrophenyl ester of an (N-protected) aminoacid, followed by coupling with an unprotected aminoacid in partially aqueous solutions. The resulting peptide is easily isolated by precipitation. In general, the yields obtained are good to excellent and racemization is minimal. This
