AbstractCopper(I)-catalyzed azide–alkyne cycloaddition reactions (CuAAC), as a versatile, reliable, and modular strategy, have been widely investigated in the area of glycoscience during the last 20 years. Herein, we presented a brief overview of CuAAC click approaches for easy access to diverse simple and complex triazole-appended carbohydrate-containing molecular architectures. Both intermolecular and intramolecular CuAAC conjugation of glycosylated azides and terminal alkynes have been widely employed for the regioselective triazole-forming reaction under standard click conditions.
