title: Carbon-CArbon bond formation by Lewis superacid catalysis.
abstract: Diverse intramolecular cyclizations involving the formation of CC bonds are described using catalytic methodologies based on Lewis superacids. Examples are presented on 1,6-diene cyclizations to gem-dimethylcyclohexane structures. Tandem cyclization of trienes are described to afford bicyclic structures in reactions involving rearrangements. Hydroarylation of olefins and of allenes is developed in catalytic FriedelCrafts-type coupling processes, which can give rise to tandem reactions. The olfactory evaluation of the series of prepared compounds is also presented.
