Paragraph 0038-0039, (2021/06/26)
The invention provides a method for synthesizing deoxycholic acid. The method comprises the steps of esterifying cholic acid to obtain a compound I, oxidizing to obtain a compound II, performing protection to obtain a compound III, brominating to obtain a compound IV, reducing to obtain a compound V, eliminating to obtain a compound VI, reducing and hydrogenating to obtain a compound VII, and performing ester hydrolysis to obtain deoxycholic acid. The reaction formula is shown in the description, wherein R1 in the formula III, the formula VI, the formula V, the formula VI and the formula VII is selected from benzoyl or p-toluenesulfonyl; and R2 is selected from methyl, ethyl or tertiary butyl. The synthesis method overcomes the defects of long reaction steps, expensive used reagents, difficulty in purification, low yield and the like in the prior art, and provides a novel method which is rapid in reaction, easy in purification, high in yield and suitable for commercial mass production.
