5~ -Vinyl phenyl sulfone reacts with aldehydes to yield sulfonylated secondary allylic alcohols which are converted to either primary allylic bromides, or secondary allylic acetates. Both react highly regioselectively with lithium cyanocuprates, or enolates. We have recently reported the mUlticoupl
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
