Four novel diterpenes were isolated from the brown alga Bifurcaria bifurcata collected off the Atlantic coast from Morocco, and their structures established by spectral and chemical methods. These compounds are acyclic diterpenes derived from (S)-12-hydroxygeranylgeraniol. One of them is its dehydration product at C-12, while the others are its oxidation derivatives: the methyl ester of the acid at
从摩洛哥大西洋沿岸采集的褐藻 Bifurcaria bifurcata 中分离出四种新型二萜,并通过光谱和化学方法建立了它们的结构。这些化合物是衍生自(S)-12-羟基香叶基香叶醇的无环二萜。其中之一是其C-12位的脱水产物,而其他则是其氧化衍生物:C-1位酸的甲酯和C-1位醛的两种立体异构体(Z和E)。这些结果是从化学分类学的角度进行讨论的。
