An unprecedented stereospecific substitution reaction of enantioenriched allylic alcohols with sodium sulfinates has been developed for the asymmetric synthesis of allylic sulfones with excellent ee. A range of highly enantioenriched allylic alcohols smoothly underwent palladium diacetate/racemic 2,2'-bis(diphenylphosphino)-1,1'-binaphthylcatalyzed substitution with sodium sulfinates to give structurally diverse a-chiral allylic sulfones in moderate to excellent yields with complete retention of configuration. This study paves the way for the direct stereospecific substitution of enantioenriched allylic alcohols with sulfur nucleophiles.
