  Synthesis of β-Thiol Phenylalanine for Applications in One-Pot Ligation–Desulfurization Chemistry

  摘要：

  The efficient synthesis of a beta-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.

  An efficient synthetic route to a suitably protected beta-selenol-phenylalanine derivative from commercially available Garner's aldehyde is described. The incorporation of this building block into peptides and its application in native chemical ligation reactions with peptide thioesters are demonstrated. Ligation products were chemoselectively deselenized (including in the presence of unprotected cysteine residues) to provide native peptides.

  The synthesis of suitably protected beta-selenophenylalanine and beta-selenoleucine amino acids was accomplished from Garner's aldehyde as a common starting point. These selenoamino acids were incorporated into model peptides and shown to facilitate rapid diselenide-selenoester ligation (DSL) with peptide selenoesters which, when coupled with in situ deselenization, afforded native peptide products. The utility of one-pot DSL-deselenization chemistry at phenylalanine and leucine was demonstrated through the rapid synthesis of a glycosylated interferon-gamma fragment and the chemokine-binding protein UL22A, respectively.
