• Total Synthesis of Teixobactin 

      Giltrap, Andrew M.; Dowman, Luke J.; Nagalingam, Gayathri; Ochoa, Jessica L.; Linington, Roger G.; Britton, Warwick J.; Payne, Richard J.
      Published 2016-05-18
      The first total synthesis of the cyclic depsipeptide natural product teixobactin is described. Synthesis was achieved by solid-phase peptide synthesis, incorporating the unusual l-allo-enduracididine as a suitably protected ...

    • Trifluoroethanethiol: An Additive for Efficient One-Pot Peptide Ligation−Desulfurization Chemistry 

      Thompson, Robert E.; Liu, Xuyu; Alonso-Garcia, Noelia; Pereira, Pedro Jose Barbosa; Jolliffe, Katrina A.; Payne, Richard J.
      Published 2014-05-15
      Native chemical ligation followed by desulfurization is a powerful strategy for the assembly of proteins. Here we describe the development of a high-yielding, one-pot ligation−desulfurization protocol that uses ...

    • Total Synthesis of Native 5,7-Diacetylpseudaminic Acid from N-Acetylneuraminic Acid 

      Williams, James T.; Corcilius, Leo; Kiefel, Milton J.; Payne, Richard J.
      Published 2016-02-23
      The pseudaminic acids are a family of 5,7-diamino-3,5,7,9-tetradeoxynonulosonic acids that are functional components of flagellin and pili proteins within clinically relevant Gram-negative bacteria. Herein, we describe the ...

    • One-Pot Peptide Ligation–Desulfurization at Glutamate 

      Cergol, Katie M.; Thompson, Robert E.; Malins, Lara R.; Turner, Peter; Payne, Richard J.
      Published 2013-12-02
      An efficient methodology for ligation at glutamate (Glu) is described. A γ-thiol-Glu building block was accessed in only three steps from protected glutamic acid and could be incorporated at the N-terminus of peptides. The ...

    • Total Synthesis of Polydiscamides B, C, and D via a Convergent Native Chemical Ligation–Oxidation Strategy 

      Santhakumar, Gajan; Payne, Richard J.
      Published 2014-08-08
      The first total syntheses of the marine sponge-derived cyclic depsipeptide natural products Polydiscamides B, C, and D are described. The molecules were constructed through the convergent fusion of cyclic and linear fragments ...
