N→S Acyl transfer is a popular method for the postsynthesis production of peptide C α-thioesters for use in native chemical ligation and for the synthesis of head-to-tail cyclic peptides. Meanwhile thioester formation at the side chain of aspartic or glutamic acids, leading to tail-to-side-chain-cyclized species, is less common. Herein we explore the potential for cysteine to function as a latent thioester when appended to the side chain of glutamic acid. Initial insights gained through study of C-terminal β-alanine as a model for the increased chain length were ultimately applied to peptide macrocyclization. Our results emphasize the increased barrier to acyl transfer at the glutamic acid side chain and indicate how a slow reaction, facilitated by cysteine itself, may be accelerated by fine-tuning of the stereoelectronic environment.

Chemical Ligation

We herein introduce a straightforward synthetic route to cysteine-containing cyclic peptides. It is based on the intramolecular native chemical ligation of thioesters generated in situ from N-Hnb-Cys crypto-thioesters. The strategy is applied to a representative range of natural cyclic disulfide-rich peptide sequences.
