Based on a strategy of ground-state destabilisation of the N-C bond, a general protocol for the esterification of amides with carbohydrates was reported. This protocol offers mild reaction conditions, excellent yields, and broad substrate compatibility, thereby demonstrating great potential for the synthesis of glycoconjugates. Additionally, this method provides an alternative approach for addressing the challenging task of esterifying sterically hindered secondary hydroxyl group of carbohydrates and paving the way for advancements in carbohydrate-based pharmaceuticals.
