the cyclized products 4-9 in good yields. The regiochemistry was found to be dominated by the phenylsulfinyl group, but could be reversed by the presence of a Lewis acid. Deprotonation of 2 by BuLi, followed by the reaction with alkyl halides, gave the substituted 2-sulfolenes 10. A syntheticapplication of 10 was demonstrated by converting 10e to the bicyclic product 11.
