Abstract
In methyl xa-7-norandrosta-4,14-dien-1-yl-methylcarboxylate, C27H34O5, several C-C bonds and C-C-C angles deviate significantly from their e xpected values, The two six-membered rings, A and C, have slightly dis torted sofa and boat conformations, Two of the five-membered rings, B and D, have half-chair and envelope conformations, and the terminal fi ve-membered ring is nearly planar. The structure is stabilized by van der Waals interactions.
