| titleOfInvention | Method for preparing epiandrosterone by using androstenedione as raw material |
| abstract | The invention relates to a method for preparing epiandrosterone by taking androstenedione as a raw material, which is characterized in that the target product epiandrosterone is obtained by performing four-step reactions of 3-carbonyl alkene esterification reaction, 17-carbonyl ketal protection reaction, hydrolysis, palladium-carbon catalytic reduction reaction, acidic hydrolysis reaction and the like on the androstenedione. Compared with the existing synthesis method, the method has the advantages of rich raw material source, low price, mild synthesis conditions, good catalyst reduction effect, high yield and lower production cost, and is suitable for industrial production. |
