| titleOfInvention | Synthesis method for 16alpha-hydroxyprednisolone |
| abstract | The invention provides a synthesis method for 16alpha-hydroxyprednisolone. According to the method, 16alpha-hydroxyprednisolone is prepared by taking 21-acetoxypregna-1,4,9(11),16(17)-tetrene-3,20-dione acetate as a reaction raw material through the four steps of preparation of an intermediate 1, preparation of an intermediate 2, preparation of an intermediate 3 and preparation of 16alpha-hydroxyprednisolone. According to the method, a synthetic route is innovated, and the advantages of being few in reaction steps, high in product yield, low in production cost, simple in unit operation, short in single batch production cycle, suitable for industrial scale production and the like are achieved. |
