Abstract
The synthesis of bile acid-3-.beta.-D-monoglucoronides was accomplished via the Koenigs-Knorr condensation reaction using methyl 2,3,4-tri-O-acetyl-1-deoxy-.alpha.-bromo-D-glucopyranuronate as coupling reagent. Chemical characteristics such as melting points, elemental analyses, IR-spectra, isobutane-chemical ionization mass spectra and, in the case of the derivative of 3.alpha.-hydroxy-5.beta.-cholanoate, NMR-spectra were recorded and can identify these recently detected, naturally occurring derivatives of bile acids in isolation procedures from biological sources. These bile acids may be useful in the diagnosis of intrahepatic cholestasis.
