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 also disclosed.
本发明公开了一种新型的norpatchoulenol合成方法。合成的关键步骤是通过环内Diels-Alder缩合反应合成三取代硅氧基环己二烯酮衍生物。同时,本发明还公开了新型中间体,即三取代硅氧基甲基萘烯(下式V)和三取代硅氧基环己二烯(下式IV)。
