Begioselective cyclopropanation of 2-phenylsulfonyl 13-dienes at either double bond was achieved by employing two different reagents. Sulfur ylide 1 cesulted in a regiospeciKc cyclopropanation at the electron deficient double bond whereas an iron carbene, thermally generated from Sn, gave cyclopropa
