Tandem Thiol Switch Synthesis of Peptide Thioesters via N–S Acyl Shift on Thiazolidine
摘要:
An efficient "thiol switch" approach for the synthesis of peptide thioesters via an acid-catalyzed N-S acyl shift and a thioester exchange reaction in tandem with concurrent removal of protecting groups is described. This method employs novel 2-(thiomethyl)thiazolidine (TMT)-anchored resins and is fully compatible with Fmoc chemistry.
