Several γ, δ-unsaturated sulfinyl compounds were prepared and their reactions with p-toluenesulfonic acid were examined. Conformationally rigid γ, δ-unsaturated sulfinyl compounds such as endo-(alkylsulfinyl)norbornene or 1-(alkylsulfinyl)-2-isopropenylbenzene derivatives afforded 1, 3-oxathianes through intramolecular Pummerer rearrangement.
