The nitration of 3 beta,17 beta-diacetoxy-7-norandrost-5-ene by fuming nitric acid leads to 3 beta,17 beta-diacetoxy-5 beta-nitroxy-6 alpha-nitro-7-norandrostane and to the rearrangement product 2. A number of minor products were also identified. The formation of these can be rationalized in terms of a Markownikoff directed diaxial (5 beta,6 alpha) addition to the Delta(5)-double bond of the B-norsteroid which contrasts with the 5 alpha,6 beta-diaxial addition found in the normal steroids.
