| titleOfInvention | Synthetic method of 16,21-cyclic hemiacetal of 17-deoxyprednisolone |
| abstract | The present invention provides a method for preparing the 16,21-cyclic hemiacetal of 17-deoxyprednisolone using budesonide. The synthetic method has the advantages of simple process route, convenient operation and high yield; the 16, 21-cyclic hemiacetal of the synthesized budesonide impurity 17-deoxyprednisolone can be used as a control for the detection and research of budesonide It is used for quality control of budesonide and its related preparations, and to control the purity of budesonide raw materials or its preparations. |
