N-Acyl Transfer Reactions in Peptide Synthesis
We have developed a new method for peptide synthesis through the Ag(I)-promoted coupling of thioamides with carboxylic acids. This process generates an isoimide, which undergoes and N-acyl transfer to generate an imide. The peptide imide can be hydrolysed to generate a native amide bond, or can undergo subsequent acyl transfer reactions to generate a range of modified peptides. We are investigating applications in peptide ligation, peptide residue excision/insertion, and peptide thioester synthesis.
