for the preparation of phenylvinyl-1,2-diamines by the Rh(II)-catalyzed C–N coupling of 1-sulfonyl-1H-1,2,3-triazoles with secondary amines (e.g., N-aryl glycine esters, diarylamines or 1-phenyl-2-(p-tolylamino)ethanone) via the 1,3-insertion of Rh(II)-azavinyl carbenes into sp 3 N-H bond process has been developed. The optimized conditions tolerate various functional groups and afford the diverse (Z)-phenylvinyl-1
摘要 通过 Rh(II) 催化的 1-磺酰基-1H-1,2,3-三唑与仲胺(例如, N-芳基甘氨酸酯、二芳基胺或1-苯基-2-(对甲苯基氨基)乙酮)通过Rh(II)-氮杂乙烯基卡宾的1,3-插入sp 3 NH键过程已被开发。优化的条件可耐受各种官能团,并以良好的收率和高区域选择性提供各种 (Z)-苯基乙烯基-1,2-二胺。该方法还成功地扩展到具有(1-芳基-2-(磺酰氨基)乙烯基)取代基和两个芳基的Z构型的官能叔胺的合成。图形概要
