The efficient synthesis of a β-thiol phenylalanine derivative is described starting from Garner’s aldehyde. The utility of this amino acid in peptide ligation–desulfurization chemistry is described, including the trifluoroethanethiol (TFET)-promoted one-pot assembly of the 62 residue peptide hormone augurin.
