Abstract
The superacidic cyclization of aliphatic and partially cyclized C 10C 20 terpenylphenylsulfones proceeds structure-selectively and stereospecifically, affording α- or mixtures of α- and γ-isomers of completely cyclized terpenylphenylsulfones. The configuration of the phenylsulfonylmethylene group in the cyclized products is predetermined by the configuration of the allylic double bond in the starting compounds.
