Lithiation of the sulfones 1-3 in THF at -78° with lithium diisopropyl amide (LDA) is regioselective, since deuteration of the α-lithiosulfone 4 results in formation of the α-monodeuteriated sulfone 7. Higher temperature causes an intramolecular 1,4-addit
SYNTHESIS OF Δ3-DIHYDROTHIAPYRAN-1,1-DIOXIDES AND THEIR RAMBERG-BAECKLUND CONVERSION TO CYCLOPENTADIENES.

Treatment of Z-sulfone 1 with n-BuLi gives complete conversion to the cyclized anion 3.The anion 3 is protonated to 4.Reaction of 3 with hexachloroethane leads to a mixture of 4, 5 and 6.Ramberg-Baecklund rearrangement of 5 with one equivalent of n-BuLi a
