Investigations on Steroids. II. Spectral Properties of Androstano [3, 2-b] pyridine.

Abstract

From the ultraviolet, infrared, and nuclear magnetic resonance spectra of androstano-pyridines which were previously prepared, the structure of the ring fusion was confirmed to be androstano [3, 2-b] pyridine. Comparison of the ultraviolet absorptions of 6'-substituted and 5', 6'-disubstituted androstano [3, 2-b] pyridines with those of the corresponding dimethylpyridine derivatives was described.
