, (2021/05/28)
The present invention relates to a process for producing bile acid derivatives having a protected hydroxyl group in the 3 position comprising contacting a bile acid derivative having an unprotected 3-alpha-hydroxyl group with a specific lipase. The present invention further relates to a bile acid derivative obtained or obtainable by the process, to the use of the bile acid derivative obtained or obtainable by the process for producing lithocholic acid and also to a process for producing lithocholic acid and to lithocholic obtained by the process. The invention further relates to the use of lithocholic acid obtained or obtainable by the process for producing ursodeoxycholic acid or ursodeoxycholic acid derivatives.

Obeticholic acid (OCA) is used to treatment for Primary Biliary Cholangitis and other Famesoid X Receptor related diseases. Through the palladium catalyzed Kumada-Tamao-Corriu cross-coupling reaction, a novel and efficient method for synthesis of OCA with satisfied yield was successfully developed. The absolute configuration of the key intermediate was confirmed by Single-crystal X-ray Diffraction. It affords good strategy for large-scale synthesis of OCA.
