The fragmentation of N-acyl-isoxazol-5-ones using visible light photoredox catalysis has been disclosed. The catalyst-controlled divergent mechanisms, namely the oxidative and reductive quenching catalytic cycle, are utilized. Various oxazoles and 1,3-oxazin-6-ones are selectively obtained from the same isoxazol-5-one skeleton under mild conditions.
已公开了使用可见光光氧化还原催化对N-酰基异恶唑-5-酮进行碎片化反应。利用了催化剂控制的不同反应机制，即氧化猝灭催化循环和还原猝灭催化循环。在温和条件下，从相同的异恶唑-5-酮骨架中可选择性地获得各种恶唑和1,3-恶嗪-6-酮。
