A stereoselective synthesis of enantiomerically enriched difluoromethyl tertiary alcohols by tuning the reactivity of difluoromethyl sulfoximines from electrophilic to nucleophilic difluoromethylating agents is reported. The key feature of this chemistry is the diastereoselective addition of the difluoromethyl sulfoximine to the prochiral carbon of the ketone. The present method was used to prepare enantiomerically enriched difluoromethyl secondary alcohols and difluorinated analogues of the natural products gossonorol and boivinian B, demonstrating the potency of the method.
