| titleOfInvention | The preparation method of deoxymetasone intermediate |
| abstract | The invention provides a method for preparing a didometasone intermediate, which starts with 21-hydroxypregnant-1, 4, 9(11), 16-tetraene-3, 20-diketone-21-acetate Material, goes through bromohydroxylation, epoxidation, methylation and hydrolysis successively, obtains deoxymetasone intermediate 9β, 11β-epoxy-21-hydroxy-16α-methylprogesterone-1,4-diene- 3,20-diketone. The preparation process route provided by the invention has fewer reaction steps, and the quality and yield of the product have obvious competitiveness, and does not involve dangerous chemical processes, is green and clean, and improves the atom economy; the preparation process has broad industrial application prospects . |
