beta-Araneosene

β–Araneosene is a molecule first isolated in 1975 from the mold Sordaria araneosa by Borschberg. This unprecedented diterpene framework was given the name “araneosene”. In 1976, the skeletal class was renamed to “dolabellane” due to the isolation of several compounds containing this framework found from the sea hare Dolabella californica. Since their initial discovery, there are now more than 150 known dolabellanes, mostly isolated from marine sources.
