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.

A concise and efficient synthesis of pyrrolo- and pyrrolidino[1,2-a]quinolin-1-ones has been developed. New members of this family can thus be generated via Diels-Alder reactions of olefins with N-acyliminium cations produced, in the presence of BF3·Et2O, from 5-hydroxy-1-arylpyrrol-2-ones and 5-hydroxy-1-arylpyrrolidin-2-ones in moderate to high yields at ambient temperature.

A novel route for the synthesis of 1H-indene derivatives via the reactions of vinylidenecyclopropanes (VCPs) with the N-acyliminium cations generated from hydroxylactams is described.
