, p. 874 - 877 (2013)
A novel expeditious and convenient synthesis of 5α-cholestano-[5,6-c] -isoxazolidin-5′-ones based on the reaction of 5α-6- hydroxyiminocholestanes with Vilsmeier-Haack reagent (DMF/POCl3) is described. The systems presented here, are novel scaffolds and have not been described before. Structural assignment of newly synthesized compounds was performed by IR, 1H NMR, 13C NMR, 2D 1H- 1H COSY, MS and analytical data.
Reduction of Steroidal Nitroolefins with Zinc-Acetic Acid without Added Water
Ahmad, M. S.,Raza, S. K.
, p. 579 - 580 (2007/10/02)
Zinc-acetic acid reduction (without added water) of steroidal nitroolefins (I-III) leads to the formation of respective N-acetylated enamines (X-XII) alongwith the parent ketones (IV-VI) and the oximes (VII-IX).These products have been identified on the basis of their spectral properties and by comparison with authentic samples where available.
