In previous papers we have reported that treatment of several steroidal nitroamines with acetic anhydride and pyridine leads to nitrogen free-products. In the study of the denitroamination of the (20R)-nitroaminopregnane derivative (1) we found that, in addition to substitution and β-hydrogen elimination products, the arearranged compounds (2) and (4) were formed.
