(20S)-20-Acet-oxy-4-pregnene-3,16-dione from Commiphora wightii.

ABSTRACT: The title triterpene compound, C(23)H(32)O(4), isolated from Commiphora wightii features four trans-fused rings, among which the five-membered ring adopts an envelope conformation, the cyclo-hexene ring adopts a half-chair conformation and the two cyclo-hexane rings exist in chair conformations. The asymmetric unit contains two independent mol-ecules. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
