A simple, efficient and racemization free method for the synthesis of peptides employing Fmoc-amino acid chlorides mediated by HOAtDCHA as a co-coupling agent has been described. This protocol is successfully employed in the synthesis of the pentapeptide H-Pro-Gly-VaI-GIy-VaI-OH (PGVGV), and ss-casomorphin (H-Tyr-Pro-Phe-Pro-Gly-OH) in 85 and 80% yields, respectively.

The synthesis of peptides containing multiple Aib residues was accomplished using Fmoc-Aib-Cl in presence of KOBt. As no additional base was added, the duration of coupling reactions could be extended. Thus, the synthesis of the alamethicin 1-4 fragment, Aib-Pro-Aib-Ala, the emerimicin 2- 6 fragment, Aib-Aib-Aib-Val-Gly and the Aib tetramer, Fmoc-(Aib)4-OBzl were accomplished in good yield and purity.

The potassium salt of 1-hydroxy-7-azabenzotriazole can be used along with acid chlorides of 9-fluorenylmethyloxycarbonylamino acids as coupling agents in peptide bond formation.The acylation reactions are rapid and efficient and can be carried out in an organic medium.The yields as well as purity of the peptides are satisfactory.
