Abstract

Electrophilic additions of Broensted acids to 1, 5-dimethylcycloocta-1, 5-diene yield syn-8- substituted 1, 5-dimethylbicyclo [3.2. 1] octanes via parallel π-cyclization and subsequent Wagner-Meerwein type rearrangements. The corresponding anti-isomers are synthesized by nucleophilic substitution in the 8-position. The classical or nonclassical structure of the cationic intermediates is discussed.
