Redetermination and absolute configuration of 7α-hydroxyroyleanone
THE TITLE COMPOUND [SYSTEMATIC NAME: 7α,12-dihy-droxy-8,12-abietadiene,11,14-dione or (4bS,8aS,10R)-3,10-dihy-droxy-2-isopropyl-4b,8,8-trimethyl-1,4,4b,5,6,7,8,8a,9,10-deca-hydro-phenanthrene-1,4-dione], C(20)H(28)O(4), is an abietane diterpen-oid, which was isolated from the roots of Premna obtusifolia (Verbenaceae). Its crystal structure has been reported previously [Chen et al. (2000 ▶). Jie...

متن کاملRedetermination and absolute configuration of (+)-7-epiclusianone
The absolute configuration of 3-benzoyl-4-hy-droxy-6,6-dimethyl-1,5,7-tris-(3-methyl-but-2-en-yl)bicyclo-[3.3.1]non-3-ene-2,9-dione, C(33)H(42)O(4), isolated from Hypericum hypericoides, has been determined. The previous study [Xiao et al. (2007 ▶). J. Nat. Prod.70, 1779-1782] gave only the established relative configuration. The three stereogenic centers are now established as 1R, 5R and 7S on...
