Autor: I. V. Zavarzin, Igor L. Dalinger, Elena I. Chernoburova, A. S. Shashkov, M. A. Shchetinina, A. Kh. Shakhnes
Publikováno v: Russian Chemical Bulletin. 67:1920-1926
Chemoselective methods for O- and N-nitration of steroids fused to the pyrazole ring were developed. The nitrating agents were acetyl, propionyl, and trifluoroacetyl nitrates generated from carboxylic acid anhydrides and either copper nitrate or nitr
