Four new unusual 19-nor-pimarane-type diterpenes were isolated from the tuber of Icacina trichantha (Icacinaceae, Oliv.). The structures were elucidated based on spectroscopic and HRMS analysis. The absolute configurations were determined by electronic circular dichroism. All four compounds are structural analogues of icacinol and humirianthol, but do not demonstrate the same cytotoxic activity. A plausible biogenetic pathway is proposed.

Icacina trichantha的19-nor-pimaranes。

从Icacina trichantha(Icacinaceae,Oliv。)的块茎中分离出四个新的不寻常的19-正-marmarane型二萜。根据光谱和HRMS分析阐明了结构。绝对构型由电子圆二色性确定。所有这四种化合物都是ICACANOL和Humirianthol的结构类似物,但没有表现出相同的细胞毒活性。提出了一条合理的生物遗传途径。
