Isomerization by base under kinetic or thermodynamic control of the Diels-Alder adduct of 1,3,3-trimethyl-2-vinyl-1-cyclohexene with dimethyl acetylene dicarboxylate leads to two isomers which, after catalytic hydrogenation, give in high yield starting materials for synthesis of trans and cis drimanes.A short total synthesis of (+/-)-polygodial and (+/-)-drimenine from one of these isomers is desribed.
