Structure of 3 beta-hydroxy-16-oxo-24-nor-17-azachol-5-eno-23-nitrile and its 20S epimer.
The structures of the title compounds have been investigated in solid state by X-ray and in solution by NMR methods. The configurations at C20 and the preferred conformations of both epimers were established. A full assignment of signals in 1H and 13C NMR spectra was done.
