bromide to generate 1,5-disubstituted-butynyl-N-aryl or N-glycosyl-1,2,3-bistriazoles in a domino fashion. Upon Cu(I) catalyzed 1,3-dipolar cycloaddition with sugar azides, these compounds afford novel unsymmetrical bis-1,2,3-triazoles in high yields.

烯丙基溴化镁处理芳基或
叠氮化物,以多米诺方式生成1,5-二取代的丁炔基-N-芳基或N-糖基-1,2,3-双三唑。在Cu(I)与糖
叠氮化物催化的1,3-偶极环加成反应后,这些化合物以高收率提供了新型不对称双
1,2,3-三唑。
