An efficient one-pot method for the regioselective bromination of allylic alcohol derivatives (two-step reaction sequence) followed by Sonogashira, Negishi, or Suzuki–Miyaura coupling reactions in the same reaction vessel (three-step reaction sequence) has been developed. The key reaction in these one-pot systems is the regioselective DBU-promoted trans HBr elimination of vicinal dibromides bearing
已经开发了一种有效的一锅法,用于烯丙醇衍生物的区域选择性溴化(两步反应顺序),然后在同一反应容器中进行 Sonogashira、Negishi 或 Suzuki-Miyaura 偶联反应(三步反应顺序)。这些一锅系统中的关键反应是区域选择性 DBU 促进的反式 HBr 消除带有相邻 O 官能团的邻位二溴化物。
