Isoindolo[2,1-a]quinolin-11-ones have been synthesized by one-pot reaction of 3-hydroxy-2-arylisoindol-1-ones with 1,3-dicarbonyls via coupling of N-acyliminium ion intermediates with 1,3-dicarbonyls and subsequent intramolecular Friedel-Crafts reactions catalyzed by H3PO4-P2O5 or H3PO4-H2SO4.
异吲哚并[2,1-a]喹啉-11-酮是由 3-羟基-2-芳基异吲哚-1-酮与 1,3-二羰基通过 N-酰亚胺离子中间体与 1,3-二羰基的偶联以及随后在 H3PO4-P2O5 或 H3PO4-H2SO4 催化下发生的分子内 Friedel-Crafts 反应而合成的。
