A One-Pot Approach to Neoglycopeptides using Orthogonal Native Chemical Ligation and Click Chemistry

Abstract

The powerful combination of native chemical ligation and click chemistry has been used to affect a one-pot synthesis of neoglycopeptides from propargyl-containing peptides using GalNAc-N(3) as the glycan component. A versatile chemical toolkit for the fully convergent synthesis of neoglycoproteins using click chemistry, native chemical ligation, and kinetically controlled ligation is thus demonstrated.
