Two-step one-potreaction conditions have been developed for synthesizing 1-substituted-1,2,3-triazoles. This transformation involves the base-catalyzed deprotection of trimethylsilylacetylene followed by Cu-catalyzed Huisgen 1,3-dipolar cycloaddition under aqueous reaction conditions. Utilization of potassium carbonate as the base and methanol as the alcoholic aqueous co-solvent resulted in optimal
