the resulting 1,2,3-triazole which spontaneously decomposed to the corresponding ketenimine. Nucleophilic attack by pyrrole and subsequent intramolecular Aza-Michael cyclization generated 1,2-dihydroisoquinolines in moderate to good yields. The optimized conditions allow for a range of substituents with excellent reproducibility.
摘要 用吡咯和各种吸电子基团作为取代基,实现了合成 1,3-二取代-1,2-二氢异喹啉的一般方法。CuAAC 与烯反应生成 1,2,3-三唑,其自发分解为相应的酮亚胺。吡咯的亲核攻击和随后的分子内 Aza-Michael 环化以中等至良好的产率生成 1,2-二氢异喹啉。优化的条件允许一系列具有出色重现性的取代基。
