Advanced Synthesis & Catalysis

A visible‐light‐promoted synthesis of quinoxalin‐2(1 H )‐ones has been developed using 9‐mesityl‐10‐methylacridinium perchlorate as an organo‐photocatalyst. The atmosphere‐controlled method (Ar/air) enabled the selective synthesis of hydroxyl‐ and acyl‐containing quinoxalin‐2(1 H )‐ones under mild reaction conditions without the use of any metal catalysts or toxic reagents. A fluorescent labelling experiment showed that hydroxyl‐containing quinoxalin‐2(1 H )‐ones may have utility in various biological applications as potent fluorophores. magnified image
