Efficient one-step synthesis of 3-(indol-2-yl)quinoxalin-2(1H)-ones via electrochemical oxidative cross-dehydrogenative coupling

A novel and efficient synthetic strategy for 3-(indol-2-yl)quinoxalin-2(1 H )-ones was developed via electrochemical oxidative cross-dehydrogenative coupling of indoles and quinoxalin-2(1 H )-ones.
