Senecio oxyodontus senoxydene from

In 1979, Bohlmann and Zdero reported the isolation and an unusual sesquiterpene hydrocarbon from Senecio oxyodontus This substance was formulated as 766 on the basis of its spectral characteristics and called senoxydene. However, Galemmo and Paquette have recently prepared this particular compound and determined that it is not identical to the natural product. Their pathway, which is summarized in Scheme LXXXVII, begins by transforming 4,4-dimethylcyclopentenone into bicyclic... 

A new tricyclic hydrocarbon, senoxydene, which has been isolated from Senecio oxyodontus, has been assigned the structure (304) on the basis of its n.m.r. spectrum together with that of the corresponding epoxide.It is suggested that once again humulene could act as the precursor (Scheme 48) see, however, p. 104.
