Article abstract of DOI:10.1016/S0040-4020(98)83049-4

The superacidic cyclization of aliphatic and partially cyclized C₁₀- C₂₀ terpenylphenylsulfones proceeds structure-selectively and stereospecifically, affording α- or mixtures of α- and γ-isomers of completely cyclized terpenylphenylsulfones. The configuration of the phenylsuffonylmethylene group in the cyclized products is predetermined by the configuration of the allylic double bond in the starting compounds.
