Herein, we report a nickel‐catalyzed intramolecular dual annulation reaction of alkyl nitrile‐containing 1,2,3‐benzotriazine‐4(3H)‐ones to synthesize polycyclic quinazolinones. This catalytic reaction can construct the core structure of polycyclic quinazolinone alkaloids; therefore, we also apply this reaction as the critical step to access fifteen relevant alkaloids to demonstrate efficacy.
在此,我们报道了含烷基腈的1,2,3-苯并三嗪-4(3H)-酮的镍催化分子内双环化反应来合成多环喹唑啉酮。该催化反应可以构建多环喹唑啉酮生物碱的核心结构;因此,我们也应用该反应作为获取十五种相关生物碱以证明功效的关键步骤。
