Germacrene D is considered as a precursor of many sesquiterpene hydrocarbons. We have investigated the acid catalyzed as well as the photochemically and thermallyinducedrearrangement processes of germacrene D isolated from several Solidago species, which contain both enantiomers of germacrene D. Enantiomeric mixtures of sesquiterpenes of the cadinane, eudesmane (selinane), oppositane, axane, isodaucane
Germacrene D 被认为是许多倍半萜烃的前体。我们研究了从几种一枝黄花物种中分离出的锗烯 D 的酸催化以及光化学和热诱导的重排过程,其中含有锗烯 D 的两种对映异构体。 cadinane、eudesmane (selinane)、oppositane、axane、异十二烷和波旁烷组以及异热菌烯 D 被确定为主要产品,并可作为参考化合物用于植物成分的结构研究和立体化学分配。重排产物之一的 Delta-amorphene 首次被确定为天然产物。γ-阿吗啡的绝对构型通过与锗烯 D 的绝对构型的相关性进行了修正。

Epicubebol has been isolated from the methanol extracts of the brown alga Dictyopteris divaricata as the major constituent. Cadinane-type sesquiterpenes, cubebenes, δ-cadinene, cubenol, and epicubenol, as well as two sesquiterpene methyl ethers as minor constituents have also been obtained from the extracts.
