We disclose herein a photocatalytic radical cascade cyclization of diazoalkanes for the divergent synthesis of important carbocycles and heterocycles. Under the optimal reaction conditions, various indanone, pyrone, and pyridinone derivatives can be obtained in moderate to good yields. Mechanistic experiments support the formation of carbon-centered radicals from diazoalkanes through the proton-coupled
我们在此公开了重氮烷烃的光催化自由基级联环化,用于重要碳环和杂环的发散合成。在最佳反应条件下,可以以中等至良好的收率得到各种茚满酮、吡喃酮和吡啶酮衍生物。机理实验支持重氮烷通过质子耦合电子转移过程形成以碳为中心的自由基。使用连续流技术的放大反应和所形成的杂环的有用下游应用进一步使该策略具有吸引力和价值。
