bicyclic diterpenehydrocarbon 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),
