A novel expeditious and convenient synthesis of 5 alpha-cholestano-[5,6-c]-isoxazolidin-5'-ones based on the reaction of 5 alpha-6-hydroxyiminocholestanes with Vilsmeier-Haack reagent (DMF/POC1(3)) 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, H-1 NMR, C-13 NMR, 2D H-1-H-1 COSY, MS and analytical data. (C) 2012 Elsevier Ltd. All rights reserved.
