ITALICENE AND ISOITALICENE, NOVEL SESQUITERPENE HYDROCARBONS FROM HELICHRYSUM OIL

From Helichrysum oil two new sesquiterpene hydrocarbons, italicene and isoitalicene were isolated.Their structure was confirmed by spectral data, degradation reactions and unambiguous synthesis starting from m-bromoanisole.

Terpenes and Terpene Derivatives, XVIII. - Concerning the Preparation of rac-γ-Curcumene

Preparation of pure γ-curcumene (3) described by Birch in 1949 via dehydratization of the alcohol 5 with SOCl2/pyridine was not reproducible.Mixtures of α-, β-, and γ-curcumene (1-3) were obtained even with POCl3/pyridine or Burgess reagent.Analogously the secondary alcohol 20 yielded mixtures of 3 and the 1,3-dienes 21 and (presumably) 22. - Li/NH3 reduction of the tert. benzyl alcohol 8 afforded after work-up directly the dienone 15 which with MeLi gave the dehydro derivative 16 of zingiberenol (17).
