The ring-opening reaction of <i>tran</i>s-2-aroyl-3-styrylcyclopropane-1,1-dicarboxylates was investigated with different Lewis acids. With SnCl<sub>4</sub>, the cyclopropane dicarboxylates afforded cyclopentene derivatives through ring opening followed by cyclization (vinylcyclopropane–cyclopentene rearrangement). With TiCl<sub>4</sub>, they furnished <i>E</i>,<i>E</i>-1,3-diene derivatives stereoselectively via ring opening followed by proton elimination
