coupling reaction were the key steps in the synthesis of precursor 1 of the aglycon of vancomycin, which already contains the complete skeleton of the target compound. The cleavage of the triazene unit from the D ring and the removal of the other protecting groups led to the aglycon of vancomycin. These strategies should be particularly valuable for the synthesis of other naturally occurring glycopeptide

The synthesis of a bicyclic tripeptide that mimics the ABC ring system of vancomycin is described by using a ring closing metathesis (RCM ) - peptide coupling - ruthenium-catalyzed azide-alkyne cycloaddition (RuAAC) strategy. (C) 2017 Elsevier Ltd. All rights reserved.
