Synthesis of Sequential Polydepsipeptides Involving Depsipeptide Formation by the 2-Nitrophenylsulphenyl N-Carboxy α-Amino Acid Anhydride (Nps-NCA) Method

Sequential polydepsipeptides containing a tripeptide sequence Ala-Ala-Glu(OEt) and various α-hydroxy acids have been successfully prepared by polycondensation of tetradepsipeptide pentachlorophenyl esters.The latter were synthesized by preparation of didepsipeptide free acids by the Nps-NCA method followed by active esterification and peptide chain elongation by the so-called 'back-up' procedure.
