Abstract
- In the title compounds, C<subscript>23</subscript>H<subscript>33</subscript>NO<subscript>3</subscript> and C<subscript>21</subscript>H<subscript>30</subscript>O<subscript>3</subscript>, 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.
