Abstract A simple and novel synthesis of 1,2,3,4-tetrahydroquinoline derivatives by polyphosphoric acid–assisted reaction of N-aryl allyl anilines prepared from anilines has been reported. The generality and scope of the approach has been demonstrated by extending it to the synthesis of 1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinoline (lilolidine) and 2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinoline
摘要 已经报道了通过多磷酸辅助由苯胺制备的 N-芳基烯丙基苯胺的反应合成 1,2,3,4-四氢喹啉衍生物的一种简单而新颖的方法。该方法的通用性和范围已通过将其扩展到 1,2,5,6-四氢-4H-吡咯并[3,2,1-ij] 喹啉(lilolidine)和 2,3,6, 7-四氢-1H,5H-吡啶并[3,2,1-ij]喹啉(julolide)。此外,已经证明了路易斯酸介导的各种 N-芳基烯丙基苯胺的氮杂-科普重排。
