Synthesis of regioisomeric 17β-N-phenylpyrazolyl steroid derivatives and their inhibitory effect on 17α-hydroxylase/C17,20-lyase

The reaction of 3β-hydroxy-21-hydroxymethylidenepregn-5-en-3β-ol-20-one (1) with phenylhydrazine (2a) affords two regioisomers, 17β-(1-phenyl-3-pyrazolyl)androst-3-en-3β-ol (5a) and 17β-(1-phenyl-5-pyrazolyl)androst-5-en-3β-ol (6a). The direction of the r
