The first example 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·OEt2mediated reactions of cyclopropenes

Methyl 2,3,3-triphenyl-, 3-methyl-2,3-diphenyl, and 2-methyl-3,3-diphenyl-cyclopropene-1-carboxylates isomerize quantitatively at 130-160 deg C to indene derivatives.The isomerization of the first two esters takes place strictly regioselectively with exclusive cleavage of the C1-C3 bond and the formation of methyl 2,3-diphenyl- and 3-methyl-2-phenylindene-1-carboxylates respectively.Isomerization of the third ester takes place in two directions, corresponding to cleavage both of the C1-C3 and of the C2-C3 bonds with the formation of methyl 2-methyl-3-phenylindene-1-carboxylate and 1-methyl-3-phenylindene-2-carboxylate in a ratio of 2.4:1.
