Optically active (E,S)-γ-hydroxy-α,β-unsaturated sulfones and (S)-Îµ-hydroxy-(E,E)-α,γ-dienyl sulfones have been prepared in a one-pot dehydration procedure from β,γ-dihydroxy sulfones and δ,Îµ-dihydroxy allyl, sulfones, respectively, via an elimination reaction of the corresponding cyclic sulfites or carbonates formed in situ by treatment with thionyl chloride or carbonyldiimidazole.
