Abstract
The title compound: 2H-10,4a-(epoxy-methano)-phenantren-12-one-1,3,4,9,10,10a-hexahydro-5,6-dihydroxy-9α-etoxy-1,1-dirnethyl-7-(1-methylethyl), was isolated fromSalvia officinalis L. andHyssopus officinalis L. C22H30O5, orthorhombic, P212121, (No. 19)a=8.309(1),b=11.320(2),c=22.060(3) A,V=2075.0(9) A3,Z=4,D x=1.199 g·cm−3, λ(CuKα)=1.54184 A,μ=6.43 cm−1, F(000)=808,T=296(1) K. The structure was solved by direct methods and refined toR=0.047 for 1824 observed reflections collected on a CAD-4 diffractometer. In the course of structure refinement conformational disorder of the isopropyl moiety and the terminal methyl group pertaining to the ethoxy ligand was established. They result altogether in four different conformers.
