The oxyarylation of alkenyl boronic acids with N-arylbenzhydroxamic acids has been achieved under both copper-mediated and copper-catalyzed conditions to provide access to interrupted Fischer-indole intermediates. This transformation is believed to proceed through a copper-promoted C–O bond forming event followed by a [3,3] rearrangement. The scope of the method is described and mechanistic experiments
在铜介导的和铜催化的条件下,已经实现了烯基硼酸与N-芳基苯并异羟肟酸的氧化芳基化,以提供接近的费歇尔-吲哚中间体的途径。据认为,这种转变是通过铜促进的C–O键形成事件继之以[3,3]重排而进行的。描述了该方法的范围并讨论了机械实验。
