Notes:
The 1H n.m.r. spectra of 3-mono-oxygenated and 3,7-dioxygenated N-acetyl-17-aza-D-homoandrost-5-enes show unequal populations of the amide rotational isomers in chloroform-d1 solution. The populations are dependent upon the orientation of the C-7 oxygen substituent but are independent of concentration. In pyridine-d5 solution the two rotameric states for each compound are almost equally populated.
