Abstract:Glycoursodeoxycholic acid could be synthesized in an overall yield of 90.2% by the following procedures. Firstly,a mixed anhydride of ursodeoxycholic acid and ethyl chloroformate was synthesized. Secondly,reaction of the anhydride with ethyl glycinate hydrochloride afforded the ethyl ester of the ursodeoxycholic acid. Finally,hydrolysis of the ester in ethanolic sodium hydroxide produced the title compound. The product was confirmed with IR and 1H NMR. |
Key words:ursodeoxycholic acid;glycoursodeoxycholic acid;ethyl chloroformate;ethyl glycinate;synthesis |
