Synthesis of azosteroid 3-aza-A-homo-cholestane-4-one, 3-aza-A-homo-coprostane-4-one and 3-aza-A-homo-cholestane-4-one from corresponding oxim and keto-steroid by means of Beckmann's and Schimdt's rearrangement by perphosphoric acid have been evaluated.

An efficient synthetic route to the trisubstituted cyclopentane as an useful synthetic intrermediate for carbaprostacyclin is described. Ireland Claisen rearrangement of a hydroxylactone has been employed as a key reaction.

The hydrazones of 2-acetylfuran, 2-acetylthiophene, and 2-acetylpyrrole, were allowed to react with S-methylthioacetimidate hydroiodide (8) to give azinoureas 10, and the reaction of 10 with Appel's dehydration conditions (triphenylphosphine/carbon tetrachloride/triethylamine) led to the corresponding azinocarbodiimides 11, which underwent thermal rearrangement under the reaction conditions to give 1,1-diheteroaryl ethylenes 13.
