  Synthesis of 6α-tritiated β-muricholic acid for use as a molecular probe

  摘要：

  Regioselective oxidation of methyl beta-muricholate to give the 6-ketoderivative is described. Stereoselective reduction of this ketone with tritiated NaBH4 furnishes labeled methyl beta-muricholate. The structure of all compounds was confirmed by infrared, H-1, and C-13 nuclear magnetic resonance spectroscopy. Data obtained by circular dichroism and mass spectroscopy were in agreement with the structure of the ketone 3.

  on analysis of beta-muricholic acid (3 alpha, 6 beta, 7 beta-trihydroxy-5 beta-cholan-24-oic acid) in biological samples by a method involving acid-catalyzed solvolysis of sulfate esters in acetone-methanol, followed by perchloric acid-catalyzed acetylation with acetic anhydride-acetic acid. These products have been identified by mass spectrometry and nuclear magnetic resonance as methyl 3-0,6-0-d
