摘要:
3H-Pyrrolo[2,1-a]isoindole-2,5-diones and isoindolo[2,1-a]quinoline-5,11-diones were synthesized by intramolecular cyclization of N-[2-oxo-3-(triphenyl-lambda(5)-phosphanylidene)propyl]- and N-[2-(triphenyl-lambda(5)-phosphanylidene)acetyl]phthalimides, respectively, in the presence of ionic liquid ([bmim][BF4], 10 mol %) as catalyst or under microwave irradiation.
