Electrochemical Oxidative C?H Cyanation of Quinoxalin-2(1H)-ones with TMSCN

Both quinoxalin-2(1H)-ones and nitriles are valuable organic compounds, and it is an interesting task to introduce cyano into quinoxalin-2(1H)-ones. Herein a regioselective C?H cyanation of quinoxalin-2(1H)-ones was developed with a nucleophilic cyano source TMSCN under electrochemical oxidative conditions. This process allowed the synthesis of C3 cyanated quinoxalin-2(1H)-ones in moderate to excellent yields in the absence of transition-metal catalysts and organic hydroperoxides.
