(20S)-24,25-Dihydr-oxy-20,24-ep-oxy-3,4-secodammar-4(28)-en-3-oic acid from Aglaia smithii.

ABSTRACT: The title compound, C(30)H(50)O(5), was isolated from the bark of Aglaia smithii. There are two independent mol-ecules in the asymmetric unit that differ in the orientation of the isopropenyl group attached to the cyclo-hexane ring. The cyclo-hexane rings in both mol-ecules adopt chair conformations, whereas the cyclo-pentane and tetra-hydro-furan rings adopt envelope conformations. The independent mol-ecules are linked into a layer parallel to (010) by O-H?O hydrogen bonds.
