Benzylcopper reagents derived by transmetallation between benzylmagnesium chloride and Cu(I) species are shown to undergo conjugateaddition - elimination with acyclic and cyclic α -oxoketene dithioacetals to afford the corresponding β-benzyl vinylogous thiolesters in highly stereo- and chemoselective manner.
