  Studies Related to the Relative Thermodynamic Stability of C-Terminal Peptidyl Esters of O-Hydroxy Thiophenol:  Emergence of a Doable Strategy for Non-Cysteine Ligation Applicable to the Chemical Synthesis of Glycopeptides

  摘要：

  A pathway has been devised, wherein a phenolic ester of a C-terminal peptide is ligated with an N-terminal peptide through two consecutive acyl migrations. In the first transacylation, the C-terminus is transferred from a phenol to a newly liberated ortho-thiol function. Subsequently, the acyl group is transported to a proximal benzylamine through a six-membered transition state.
