The intramolecular Pummerer rearrangement of 2-(2-alkyl-sulfinylphenyl)- 2-propanols (1a, 1c-1g) yielded 1,3-oxathianes (2a, 2c-2g) in the presence of p-toluenesulfonic acid and molecular sieves 3A. Alkyl halides were converted into 1,3-oxathiane derivatives in three steps via this rearrangement.

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.
