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.
已经公开了使用可见光光氧化还原催化的N-酰基-异恶唑-5-酮的断裂。利用了催化剂控制的发散机理,即氧化和还原淬灭催化循环。在温和条件下,可从相同的异恶唑-5-酮骨架选择性地获得各种恶唑和1,3-恶嗪6-1酮。
