title: Lewis Acid catalyzed reactions of vinylidenecyclopropanes with activated carbon-oxygen double bond: a facile synthetic protocol for functionalized tetrahydrofuran and 3,6-dihydropyran derivatives.
abstract: A number of functionalized tetrahydrofuran and 3,6-dihydropyran derivatives are prepared selectively in moderate to good yields by the reactions of vinylidenecyclopropanes with activated carbonyl compounds in the presence of Lewis acid.
