The unusual bile acids 3 beta,12 alpha- (V), 3 beta,7 alpha- (XIIIa), and 3 beta,7 beta- (XIIIb) dihydroxy-5-cholen-24-oic acids were synthesized conveniently from the 3-oxo derivatives of deoxycholic (I) and lithocholic (VI) acids, respectively, to provide authentic samples for the gas chromatography-mass spectrometric determination of these bile acids in the abnormal metabolism of bile acids.
