描述了一种可见光引发的 C N交叉偶联反应,其特点是无金属和无光催化剂,在环境温度下,以空气为氧化剂,频哪醇硼烷为还原剂。具有吸电子基团的底物比具有给电子基团的底物具有更高的产率,但取代基位置对产率的影响可以忽略不计。此外,进行了DFT计算,结果与自由基反应机理相吻合。该反应为吴茱萸碱及其衍生物的合成提供了一种简单且环保的方法。
This reaction does not use transition metals, has a broad substrate scope, and can be used on a gram scale. Under the optimal reaction conditions, a variety of quinazolinone-fused tetrahydroisoquinolines and derivatives of Rutaecarpine were synthesized from readily accessible compounds. The reaction proceeds well with crude 2-aminobenzamide derivatives, allowing for the synthesis of the products from
