(−)-Dihydrocarvone was converted into (−)-(4aR, 8aR)-3,4,4a,5,6,7,8,8a-octahydro-4a, 8,8-trimethylnaphthalene-2(H)-one (1) via an efficient route in which a Wolff-Kishner reduction, accompanied with a double bond isomerisation brought on a major simplification. Ketone 1 is a suitable intermediate for the syntheses of the insectantifeedants (−)-polygodial and (−)-warburganal. (+)-Dihydrocarvone was
(-)-二氢香芹酮被转化为(-)-(4aR,8aR)-3,4,4a,5,6,7,8,8a-八氢-4a,8,8-三甲基萘-2(H)- (1)通过沃尔夫-基什纳(Wolff-Kishner)还原并伴有双键异构化的有效途径,大大简化了反应。酮1是合成昆虫抗饲料(-)-多头体和(-)-warburganal的合适中间体。(+)-二氢香芹酮转化为(+)-(4aR,7S,8aR)-4a,7-二甲基-8-亚甲基-3,4,4a,5,6,7,8,8a-八氢萘-2(1H)-一(2),是合成(-)-穆济加迪尔的中间体酮。
