-
Paragraph 0035; 0061-0064, (2022/03/27)
The invention provides a palamethasone acetate and a preparation method of palamethasone, 16-methyl hydroxyl epoxy progesterone is used as an initial raw material, fluorination, bromination, debromination, iodination and replacement reaction are sequentially performed to obtain the palamethasone acetate, and then the palamethasone acetate is hydrolyzed to obtain the palamethasone. The preparation process route provided by the invention has fewer reaction steps, the quality and yield of the product have obvious competitiveness, dangerous chemical processes are not involved, the method is green and clean, and the atom economy is improved; the preparation process has a wide industrial application prospect.
