Softly does it: The title reaction, catalyzed by a AgPF6/(R)‐biphep‐type ligand/DBU complex, is described (see scheme). This protocol gives efficient access to syn‐configured α‐sulfanyl‐β‐hydroxy lactones in a highly enantioselective manner. In one particular case, the sulfide group was stereospecifically replaced with a hydroxy group to afford an enantioenriched tertiary alcohol, which upon further
