A novel norpatchoulenol synthesis is disclosed. The key step in the synthesis is an intramolecular Diels-Alder condensation of a trisubstituted silyloxy derivative of cyclohexadienone. Novel intermediates, namely trisubstituted silyloxy methanonaphthalenes (Formula V, infra) and trisubstituted silyloxy cyclohexadienes (Formula IV, infra) are prepared.
