(-)-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 converted into (+)-(4aR,7S,8aR)-4a,7-dimethyl-8-methylene-3,4,4a,5,6,7,8,8a-octahydronaphthalene-2(1H)-one (2), an intermediate ketone for synthesis of (-)-muzigadial.
