Quinolones and isoquinolones exhibit diverse biological and pharmaceutical activities, and their synthesis is highly desirable under mild conditions. Here, a highly efficient and environmentally friendly visible light-mediated aerobic oxidation of readily available N-alkylpyridinium salts has been developed with Eosin Y as the organic photocatalyst and air as the terminal oxidant, and the reaction
喹诺酮类和异喹诺酮类具有多种生物和药物活性,它们的合成在温和条件下非常理想。在这里,以曙红Y为有机光催化剂,空气为末端氧化剂,开发了一种高效且环保的可见光介导的易获得的N-烷基吡啶盐的有氧氧化,该反应以良好的收率提供了喹诺酮类和异喹诺酮类。该方法显示出许多优点,包括条件温和、环境友好、效率高、对宽官能团的耐受性和成本低。此外,使用我们的方法有效地制备了具有重要药物活性的4-脱氧亚胺。因此,本方法应为合成和修饰 N-杂环提供一种新颖且有用的策略。
