Herein, substituted 6,6a-dihydroisoindolo[2,1-a]quinolin-11(5H)-ones were synthesized from 3-substituted isoindolinones following a NaBH4 ketone reduction and carbocation-mediated intramolecular electrophilic aromatic substitution using BF3·OEt2. Representative final products were unambiguously characterized by single-crystal X-ray crystallography.
