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

A one-pot procedure for the transformation of a 1,3-diene into the corresponding 2-(phenylsulfonyl)-1,3-diene was developed. The reaction involves a 1,2-selenosulfonation-oxidation sequence. 2-( Phenylsulfonyl)-1,3-dienes have recently been shown to be versatile synthons in organic transformations.
