Abstract
The synthesis of bile acid-3-beta-D-monoglucuronides has been 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 as melting points, elemental analyses, IR-spectra, isobutane-chemical ionization mass spectra and, in case of the derivative of 3alpha-hydroxy=5beta-cholanoate, NMR-spectra were recorded and can serve as a means of identification of these recently detected naturally occurring derivatives of bile acids in isolation procedures from biological sources.
