- Facial synthesis of key intermediate of obeticholic acid via Pd-catalyzed Kumada-Tamao-Corriu cross-coupling reaction
-
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.

- A Facile Route to Ursodeoxycholic Acid Based on Stereocontrolled Conversion and Aggregation Behavior Research
-
A facile route to ursodeoxycholic acid (UDCA) and its aggregation behavior in aqueous phase solution, which is rarely known, are reported. The starting material, hyodeoxycholic acid (HDCA), is a relatively less expensive material and more easily obtained compared with chenodeoxycholic acid (CDCA). A facile route was developed to synthesize UDCA from HDCA with a Shapiro reaction as the key step and in 26% overall yield. A new strategy using organosilane reagent considering its stability, nontoxicity, and abundance in nature was carried out for a more rapid route and higher yield. It was found that the critical micelle concentration value, which is a critical value for surfactants of bile salts, was influenced by the number of hydroxyl groups.

- An efficient synthesis of 4β and 6α-hydroxylated bile acids
-
An efficient method for the preparation of 4β- and 6α-hydroxylated bile acids has been developed.It involved a highly stereoselective acetoxylation at the 4β and 6α positions of 3- and 7-oxo bile acids, respectively, with lead tetraacetate in the presence of boron trifluoride etherate in acetic acid.Reduction of the resulting α-acetoxy ketones with sodium borohydride or tert-butylamine borane complex, and alkaline hydrolysis, provided the desired bile acids in good yields. Keywords: sterols; bile acid; 4β-hydroxylated bile acid;6α-hydroxylated bile acid; acetoxylation; lead tetraacetate oxidation
