Allylic sulfones as allyl anion equivalents: homoallylic alcohols from metal catalysed reactions of sulfones with aldehydes and ketones
Abstract
Reduction of allylic sulfones with diethylzinc, catalysed by palladium(0), gives nucleophilic organometallic species, which react in situ with carbonyl compounds to give homoallylic alcohols in high yield.
