The firstexample of the reactions of cyclopropenes with N-acyliminium cations is described. 3-(1H-Inden-3-yl)isoindolin-1-ones and cyclopropa[c]isoindolo[2,1-a]quinolones were prepared by BF3·OEt2 mediated reactions of cyclopropenes with the N-acyliminium cations, generated from 2-aryl(benzyl)-3-hydroxyisoindolin-1-ones.
