20‐Hydroxy­imino‐5α‐pregna‐9(11),16‐dien‐3β‐yl acetate and 17‐oxo‐5α‐androst‐9(11)‐en‐3β‐yl acetate

In the title compounds, C23H33NO3 and C21H30O3, respectively, the ester linkage in ring A is equatorial. In these steroids, the six-membered rings A and B have chair conformations, but ring C can be better described as a half-chair. The five-membered ring D adopts a 14α-envelop conformation. The A/B, B/C and C/D ring junctions are trans.
