| 摘要 |
Steroido[3.2-c]pyrazoles, having endocrinological, including anabolic, activities, are prepared by interacting 2-(1-hydroxyalkylidene)-3-oxo steroids with hydrazine or a substituted hydrazine. The intermediate 2-(1-hydroxyalkylidene)-3-oxo steroids are in turn prepared by interacting a 3-oxo steroid with a lower-alkyl lower-alkanoate in the presence of a strong base.
