Glycosylazides undergo smooth 1,3-dipolarcycloaddition with benzyne generated in situ from 2-(trimethylsilyl)phenyltrifluoromethanesulfonate and cesium fluoride under mild conditions to furnish 1,2,3-benzotriazole-linked glycoconjugates in excellent yields and with high stereoselectivity. This method provides a novel class of benzotriazole linked glycoconjugates in a single-step reaction. This is
