Farnesol (3a) is the precursor to the irregular C12 terpenoid (4S, 4aS, 8aS)-1,2,3,4,4a,5,8,8a-octahydro-4,8a-dimethylnaphthalen-4a-ol (= dehydrogeosmin; 1). The irregular C-backbone originates from the oxidative removal of a C3 side chain from a C15 eudesmane-type intermediate (Scheme 2). The bicyclic C-framework is assembled by a formal addition of H2O across the endocyclic double bonds of a monocyclic
