Synthesis of Steroidal Pyrazoles

Stigmast-4-en-6-one (I) reacts with phenylhydrazine to afford the pyrazole (VI) whereas with 6-oxostigmast-4-en-3β-yl acetate (II) and stigmast-4-ene-3,6-dione (III) the same pyrazole (VII) is obtained.Cholesta-2,4-dien-6-one (IV) gives the pyrazole (VIII).The epoxyketone (V) provides the pyrazole (IX).The structures of the products are supported by their elemental analyses and spectral data.
