The reaction of phenyl vinyl sulfone with various aldehydes in the presence of a catalytic amount of DABCO furnishes in good yields teh corresponding 2-phenylsulfonyl-substituted alcohols which can be easily converted into their acetates or into their allylicallyrearrangedbromides . These reagents, in turn, react with nucleophides (ketone enolates and cuprates) with an allylicrearrangement (SN2′
