An efficient Lewis acid‐catalyzed C(sp3)–C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro‐5H‐isoquinolino[2,1‐g][1,6]naphthyridine derivatives. A wide range of 2‐methylquinoline‐3‐carbaldehydes and 1,2,3,4‐tetrahydroisoquinolines can be applied for this process to afford structurally diverse tetrahydroprotoberberine
已经开发出有效的路易斯酸催化的C(sp 3)–C(sp 3)键形成环化反应。该策略为轻松合成四氢-5 H-异喹啉代[2,1- g ] [1,6]萘啶衍生物提供了一种新方法。各种2-甲基喹啉-3-甲醛和1,2,3,4-四氢异喹啉都可用于该工艺,从而以优异的收率提供结构多样的四氢小ber碱衍生物。
