(4aS,10aS)-7-Hydr-oxy-8-isopropyl-1,1,4a-trimethyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthrene: a new diterpenoid compound.

ABSTRACT: The new title diterpenoid compound, C(20)H(30)O, is a natural product isolated from Tetra-clinis articulata wood via chloro-form extraction. The asymmetric unit contains four mol-ecules with the same S,S configuration, deduced from the chemical synthesis. Indeed, an overlay analysis, calculated using structure-matching software, shows that the four mol-ecules can be superimposed. The central ring has a half-chair conformation, whereas the saturated ring displays a chair conformation.
