An efficient method for copper-catalyzed cross-coupling of 1,1-dibromo-1-alkenes with sulfonamides has been achieved by a rosin-based surfactant-enabled micellar catalysis. A variety of ynamides can be prepared in water under micellar conditions. This method features broad substrate scope, good functional group tolerance, great recyclability, and green solvent.
通过基于
松香的表面活性剂胶束催化,实现了一种
铜催化的 1,1-二
溴-1-烯烃与磺
胺类交叉偶联的有效方法。可以在胶束条件下在
水中制备多种ynamides。该方法具有底物范围广、官能团耐受性好、可回收性好、
溶剂绿色等特点。
