Abstract

Expeditious syntheses of -1-methyl-2,3,3,4,5,9-hexahydro-1-pyrrolo-[3,2]isoquinoline /[2,3-]quinoline have been developed. The syntheses started with commercially available material and afforded excellent overall yields in straightforward steps. Intramolecular azomethine ylide-alkene [3+2] cycloaddition is the key step in the construction of these pyrroloisoquinoline and pyrroloquinoline scaffolds. This route is much more atom-economic than those reported in the literature and appropriate for scale-up synthesis.

摘要

已开发出-1-甲基-2,3,3,4,5,9-六氢-1-吡咯并-[3,2]异喹啉/[2,3-]喹啉的快速合成方法。该合成以市售原料开始,通过简单步骤获得了优异的总收率。分子内甲亚胺叶立德-烯烃[3+2]环加成是构建这些吡咯并异喹啉和吡咯并喹啉骨架的关键步骤。该路线比文献报道的那些路线具有更高的原子经济性,适合放大合成。
