10,13-Dimethyl-16-oxo-4,5,6,7,8,9,10,11,12,13,14,15,16,17-tetra-deca-hydro-1H-cyclo-penta-[a]phenanthren-17-yl acetate.


ABSTRACT: In the title compound, C(21)H(30)O(3), the five-membered ring adopts an envelope conformation, the cyclo-hexene ring displays a half-chair conformation and the two cyclo-hexane rings have normal chair conformations. In the crystal structure, weak inter-molecular C-H?O hydrogen bonding links the mol-ecules into supra-molecular chains running along [100].
