The invention discloses a method for synthesizing ursodeoxycholic acid. The plant-derived compound BA is used as a raw material, and the ursodeoxycholic acid is synthesized through the steps of ethylene glycol protection, oxidation, extension of side chain reaction, deethylene glycol protection, reduction, hydrolysis and the like. Ursodeoxycholic acid. The raw materials used for synthesizing ursodeoxycholic acid in the invention are cheap and easy to obtain, the synthesis steps are simple and easy to operate, the yield is high, the environment is friendly, and the industrial production is convenient. |
