One-pot synthesis of substituted-amino triazole-glycosides.

This work combined three classes of compounds in the same molecule "amino triazole-glycoside" and developed a convenient method for the synthesis of this type of compound via a one-pot two step reaction. Alkylation of amine derivatives with propargyl bromide to give propargylamine was performed in the first step subsequently followed by a 'click' reaction with various β-azido-glycosides in the presence of CuI in aqueous solution to provide β-amino triazole-glycosides. Thirty-two examples of glycosides were obtained in moderate to good yield using this one-pot procedure.
