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.
