oxidative dearomatization of indoles leading to 2,3-dialkoxy or 2,3-diazido indolines under undivided conditions at a constant current. This operationally simple electro-oxidative procedure avoids the use of an external oxidant and displays excellent functional group compatibility. The formation of the two C-O or C-N bonds is believed to arise from the oxidation of the indoles into radical cation intermediates
我们报告了使用电化学对吲哚进行直接氧化脱芳构化,在恒定电流下在未分开的条件下产生 2,3-二烷氧基或 2,3-二叠氮二氢吲哚。这种操作简单的电氧化程序避免了使用外部氧化剂并显示出优异的官能团兼容性。两个 CO 或 CN 键的形成被认为是由吲哚氧化成自由基阳离子中间体引起的。
