Abstract
AbstractBoth 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.
