摘要

本文公开了一种利用空气（O2）作为绿色氧化剂，通过酸促进喹喔啉-2(1H)-酮在 C-3 位的自光催化区域选择性氧化制备喹喔啉-2,3-二酮的有效方法。该方案为制备喹喔啉-2,3-二酮衍生物提供了一条新的合成路线，其特点是反应条件温和、操作简单、底物范围广，无需外加光催化剂、金属试剂和强氧化剂。

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 (O₂) 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.
