Preparation method of palace progesterone

The invention relates to the technical field of preparation of pharmaceutical active pharmaceutical chemicals, in particular to a preparation method of palace progesterone. To the preparation method, 17 α - hydroxyl progesterone is used as a substrate, and nucleophilic addition reaction is carried out in sequence. An epoxidation reaction, an open-loop addition reaction, an elimination reaction, an esterification reaction and a hydrolysis reaction are adopted to obtain the toecliptin progesterone, and a precious metal catalyst and a carcinogenic solvent are not used in the preparation process simultaneously. ≥ 91%.
