, p. 286 - 288 (1983)
The roots of Ferula lapidosa Eug.Korov. have yielded lapiferinin, C26H36O8, mp 157-158 deg C, 21D +63 (c 1.3; chloroform) - a diester of a new carotane alcohol, lapiferinol, with veratric and acetic acid.On the basis of chemical transformations and spectral characteristics, the structure of 2α-acetoxy-6β-veratroyloxy-8α,9α-epoxy-trans-carotan-4β-ol is proposed for it.

The structure and stereochemistry of a new carotane ester, pallidin, isolated from the roots of Ferula pallida have been established by x-ray structural analysis.Its spectral characteristics and chemical properties have been studied.
The role of germacrene D as a precursor in sesquiterpene biosynthesis: Investigations of acid catalyzed, photochemically and thermally induced rearrangements
Buelow, Nils,Koenig, Wilfried A
, p. 141 - 168 (2007/10/03)
Germacrene D is considered as a precursor of many sesquiterpene hydrocarbons. We have investigated the acid catalyzed as well as the photochemically and thermally induced rearrangement processes of germacrene D isolated from several Solidago species, which contain both enantiomers of germacrene D. Enantiomeric mixtures of sesquiterpenes of the cadinane, eudesmane (selinane), oppositane, axane, isodaucane, and bourbonane group as well as isogermacrene D were identified as main products and made available as reference compounds for structure investigations and stereochemical assignments of plant constituents. δ-Amorphene, one of the rearrangement products, was identified as a natural product for the first time. The absolute configuration of γ-amorphene was revised by correlation with the absolute configuration of germacrene D. The mechanisms of the rearrangement reactions are discussed.

Lapiferin, C22H34O6, m.p. 137-138 deg C, 21D +63 (c 1.3; chloroform), a diester of the new carotane alcohol lapiferol with angelic and acetic acids, has been isolated from the roots of Ferula lapidosa Eug.Korov.On the basis of chemical transformations and spectral characteristics, the structure of 10α-acetoxy-6α-angeloyloxy-8α,9α-epoxy-trans-carotan-4β-ol has been proposed for it.
STABLE CARBOCATIONS FROM TERPENOIDS. II. MOLECULAR REARRANGEMENTS OF DIASTEREOMERIC CARBOCATIONS FROM SOME NATURAL SESQUITERPENES OF THE CADALENE TYPE
Polovinka, M. P.,Osadchii, S. A.,Korchagina, D. V.,Dubovenko, Zh. V.,Barkhash, V. A.
, p. 1081 - 1087 (2007/10/02)
The molecular rearrangements in the diastereomeric allylic cations generated from (-)-α-murolene, (-)-zonarene, (+)-γ-cadinene, and (-)-trans-isocadinene were investigated at temperatures between 20 and 70 deg C.A mechanism involning "rotation" of the saturated six-membered ring by 180 deg in relation to the ring of the allylic cation condensed with it is proposed for these transformations.Change in the configuration of the substituents at one of the asymmetric centers C6, C9, or C10 has a significant effect on the direction of the reactions.
