Acid‐Promoted Self‐Photocatalyzed Regioselective Oxidation: A Novel Strategy for Accessing Quinoxaline‐2,3‐diones
Disclosed here is an efficient approach for the preparation of quinoxaline-2,3-diones using air (O<sub>2</sub>) as a green oxidant via acid-promoted self-photocatalyzed regioselective oxidation of quinoxalin-2(1H)-ones at C-3 position. This protocol presents a novel synthetic route for the preparation of quinoxaline-2,3-dione derivatives, featuring mild reaction conditions, simple operation, and a wide range of substrates, without the need for external photocatalysts, metal reagents, and strong oxidants.
