Abstract
The superacidic cyclization of aliphatic and partially cyclized C-15-C -25 terpenoid acids and their esters proceeds structure-selectively an d stereospecifically, affording a-isomers of completely cyclized epime ric beta,gamma-unsaturated acids of esters; the configuration of their carboxylic or ester groups is predetermined by the configuration of t he double bond conjugated with the carboxyl or ester groups in the sta rting compounds.
