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 described
1,3,3-三甲基-2-乙烯基-1-环己烯的1,3,3-三甲基-2-乙烯基-1-环己烯的Diels-Alder加合物在动力学或热力学控制下通过碱进行异构化与二甲基乙炔二羧酸酯反应生成两种异构体,这些异构体在催化氢化后可提供高收率的原料用于合成反式和顺式drimanes。描述了由这些异构体之一的短的全合成(±)-多聚体和(±)-豆蔻碱。
