含苯磺酰胺功能团的1,2,3-三唑类化合物的合成

Synthesis of 1,2,3-triazoles with benzenesulfonamide functional group

以4-乙炔基苯磺酰胺和有机叠氮化合物为原料,以CuI-抗坏血酸钠为催化剂,通过1,3-二极环加成反应高产率地合成了一组标题化合物。目标化合物的结构1HNMR、13CNMR和元素分析予以确证。

A series of 1,2,3-triazoles with benzenesulfonamide functional group were synthesized in high yields by the 1,3-dipolar cycloaddition reaction between 4-ethynylbenzenesulfonamides and organic azides catalyzed by CuI-sodium ascorbate system.The structures of the target compounds were determined by 1HNMR,13CNMR and elemental analysis.
