Abstract:

The reaction of a series of sulfonyl-containing azides and terminal alkynes indicated that the combination of copper sulfate/substituted thiourea was more suitable for general copper-catalyzed azide-end alkyne ring addition[Cu(Ⅰ) catalyzed azide-alkyne cycloaddition, CuAAC] reaction. The type of reaction was also possible to efficiently catalyze the synthesis of N-sulfonyl-1,2,3-triazole in the aqueous phase. The type of reaction was not sensitive to water and the yield was up to 99% in the aqueous phase. The reaction mixture was stirred in the air under room temperature(25 ℃). The novel system showed high atom-economy and functional-group tolurance. It provided a simple and efficient synthesis method for the synthesis of a series of N-sulfonyltriazoles.

Key words: Azide, Cu(Ⅰ) catalyzed axide-alhyne cycloaddition(CuAAC) reaction;, Aqueous phase, N-Sulfonyltriazole
