A method for the efficient enantioselective oxytrifluoromethylation of alkenes has been developed using a copper catalyst system. Mechanistic studies are consistent with a metal-catalyzed redox radical addition mechanism, in which a C–O bond is formed via the copper-mediated enantioselective trapping of a prochiral alkyl radical intermediate derived from the initial trifluoromethyl radical addition.
已开发出一种使用铜催化剂体系对烯烃进行高效对映选择性氧三氟甲基化的方法。机理研究与金属催化的氧化还原自由基加成机理一致,其中通过铜介导对映选择性捕获由最初的三氟甲基自由基加成产生的前手性烷基自由基中间体形成C-O键。
