An efficient and alternative isatin‐to‐quinoline strategy illustrates the metal‐like behavior of molecular iodine in the N−O reduction of ketoxime acetates. This process involves N−O/C−N bond cleavages and C−C/C−N bond formation to furnish pharmacologically significant quinoline‐4‐carboxamide derivatives. In this process, metal catalysts and extra oxidants are unnecessary. Mechanistic studies confirm
一种有效的替代品,从靛红到喹啉的策略说明了在碘化乙酸酮肟的N-O还原中分子碘的金属样行为。此过程涉及N / O / C-N键断裂和C-C / C-N键形成,以提供具有药理学意义的喹啉-4-羧酰胺衍生物。在此过程中,不需要金属催化剂和额外的氧化剂。机理研究证实了分子碘在亚氨基自由基生成过程中的关键作用,因为分子碘可以类似于过渡金属的方式催化单电子还原偶联反应。
