bicyclic diterpene hydrocarbon δ-araneosene (4), endowed with the dolabellane skeleton, was prepared from geraniol in two different ways. The more efficient route involved 13 steps and proceeded with an overall yield of 3.6% (average: 77% per step). With this reference sample at hand, the hitherto elusive metabolite (−)-4, a likely biogenetic precursor of cycloaraneosene ((−)-3) and sordaricin ((−)-1),
由香叶醇以两种不同方式制备了具有多萘烷骨架的双环二萜烃δ-芳烃(4)的外消旋体。效率更高的路线涉及13个步骤,总产率为3.6%(平均:每个步骤77%)。有了这个参考样品,迄今可以从中分离出纯度≥≥99.5 %的迄今难以捉摸的代谢物(-)- 4,这可能是环芳烃((-)- 3)和索达霉素((-)- 1)的生物遗传前体。霉菌Sordaria araneosa CAIN(子囊菌)的中性馏分。
