A novel iron-catalyzed ring opening of cyclopropanols and their 1,6-conjugate addition to p-quinone methides for accessing substituted phenols is disclosed. In this protocol, various cyclopropanols are converted to alkyl radicals and undergo 1,6-conjugate addition to p-quinone methides toward C–C bond formation. The salient features of this methodology include operationally simple and mild reaction
公开了一种新的铁催化环丙醇开环及其与对醌甲基化物的1,6-共轭加成以获得取代酚。在该协议中,各种环丙醇转化为烷基自由基,并与对醌甲基化物进行 1,6-共轭加成,从而形成 C-C 键。该方法的显着特点包括操作简单和温和的反应条件、环境友好的协议、高效、廉价的催化剂、良好的产率以及广泛的底物范围。
