title: Tetrahydrothiophene-catalyzed synthesis of benzo[n.1.0] bicycloalkanes.
abstract: A catalytic intramolecular cyclopropanation for the preparation of benzobicyclic compounds with [n.1.0] units has been developed. In the presence of 20 mol % of tetrahydrothiophene, the reactions of compounds 2a-2h afford versatile benzo[n.1.0]bicycloalkanes with excellent stereoselectivity in moderate to good isolated yields.
