Abstract
This non-natural steroid compound bears an isopropenyl substituent at C3, a methoxycarbonyl group at C10 and a benzoyloxy group at C17. The relative stereochemistry is cis for the A/B ring junction, anti betwee n MeO2C-Cl0 and H-C9, trans for the B/C ring junction, syn between H-C 8 and HO-C14 and cis for the C/D ring junction, and a chair-boat-chair conformation is adopted.
