8. Diterpenoids from Sideritis arborescenssubsp. Paulii

Author

Garcia-Granados, Andrés, Martínez, Antonio, and Onorato, M.Esther

Abstract

Several ent-labda-13(16),14-dienes, ent-13-epi-manoyl oxides and the new natural products ent-6α,8α-dihydroxylabda-13(16),14-diene, ent-18-hydroxy-15(16)peroxylabd-13-ene,ent-16,18-dihydroxymanoyl oxide, ent-13-epi-16,18-dihydroxymanoyl oxide and ent-6α16,18-trihydroxymanoyl oxide have been isolated from Sideritis arborescenssubsp. paulii. The structures of these compounds have been established by spectroscopic means and chemical correlations.

13. Terpenoids from Sideritis varoisubs oriensis

Author

Garcia-Granados, Andrés, Martinez, Antonio, Molina, Antonio, and Onorato, M. Esther

Abstract

From the aerial parts of Sideritis varoisubs. oriensisthe previously known 1 β-hydroxy-6β-acetoxyeudesm-4(15)-ene, 1β-hydroxy-6β-acetoxyeudesm-3-ene,1β-hydroxy-6β-acetoxyeudesm-4-ene, 1β,4β-dihydroxy-6β- acetoxyeudesmane and the new 1 β,4α-dihydroxy-6β-acetoxyeudesmane, as well as the ent-8α-hydroxylabda-13(16), 14-dienes 6-deoxyandalusoic acid, 6-deoxyandalusal, 6-deoxyandalusol, 18-deoxyandalusol, andalusol, the ent-13-epi- manoyl oxide varodiol and the ent-kaur- 15-ene sideridiol were isolated. The stereochemistry at C-4 of the isolated eudesmanes, which has been under discussion for other similar compounds, was elucidated by chemical and spectroscopic means.
