| titleOfInvention | Preparation method for progesterone intermediate |
| abstract | The invention relates to a preparation method for a progesterone intermediate. According to the method the progesterone intermediate III is prepared from a compound I through two steps of calcium hypochlorite oxidation and chromic anhydride oxidation. And the product progesterone intermediate III can be synthesized into progesterone through two steps of reaction. The reaction route is shown in the specification. According to the method, stigmasterol is taken as raw material, and the method has the characteristics that the resources are more abundant, the synthesis time is short, the efficiency is high, and the synthesized intermediate is high in purity. |
