本文描述了以酰氧基亚硝基化合物为自由基源的quinoxalin-2(1 H )-ones的光引发自由基中继反应。尽管已经研究了quinoxalin-2(1 H )-ones的C-H官能化,但很少报道其双官能化,即直接通过自由基中继反应同时构建C-C和N-N键。此外,所获得的产物在温和条件下经历了顺序反应以获得喹喔啉-2(1 H )-酮的C7-NO 2 。

An atom‐economic intermolecular radical addition reaction of acyloxy nitroso compounds to electron‐deficient alkenes mediated by visible light is reported. The starting nitroso derivatives are readily prepared by oxidation of the corresponding oximes prepared from ketones and the overall transformation represents an oxidative coupling of a ketone with a Michael acceptor. The cascade proceeds smoothly
