title: Intermolecular tandem addition-cyclization of bromoallenes: a facile synthesis of methylenecyclopropyl carboxylates and polysubstituted furans.
abstract: The base-mediated reactions of 1,3-dicarbonyl compounds with bromoallenes used as an allyl dication equivalent were explored. The corresponding dimethyl methylenecyclopropane-1,1-dicarboxylates and 2,3,4-trisubstituted furans were efficiently synthesized. [reaction: see text]
