• Synthesis of 3-glucuronides of unconjugated and conjugated bile acids.

  The 3-glucuronides of unconjugated, glyco- and tauro-conjugated bile acids have been prepared by an unequivocal route. Among three synthetic routes leading to the desired compounds, a method involving glucuronidation of the p-nitrophenyl ester by means of the Koenigs-Knorr reaction and subsequent conversion of the activated ester into the glyco-and tauro-conjugates was found to be most suitable. The nuclear magnetic resonance spectral data for bile acid glucuronides and related compounds are tabulated.

  非结合胆汁酸、糖结合胆汁酸和牛磺结合胆汁酸的 3-葡萄糖醛酸苷是通过一种明确的途径制备出来的。在获得所需化合物的三种合成路线中，通过柯尼希斯-克诺尔（Koenigs-Knorr）反应对硝基苯酯进行葡萄糖醛酸化，然后将活化的酯转化为糖型和牛磺酸型共轭物的方法最为合适。胆汁酸葡萄糖醛酸和相关化合物的核磁共振光谱数据已列表。
• Synthesis of N-acetylglucosaminides of unconjugated and conjugated bile acids

  3-N-Acetylglucosaminides of unconjugated, glycine- and taurine-conjugated bile acids have been synthesized. Bile acids appropriately protected were condensed with acetochloroglucosamine through the 3 alpha-hydroxyl group by means of the Koenigs-Knorr reaction using cadmium carbonate as a catalyst. Subsequent borohydride reduction and/or alkaline hydrolysis provided desired 3-N-acetylglucosaminides of unconjugated bile acids. Glycine-conjugates were obtained from N-acetylglucosaminides of unconjugated bile acids and ethyl glycinate by the carbodiimide method. The preparation of N-acetylglucosaminides of taurine-conjugates was attained by the Koenigs-Knorr reaction of bile acid p-nitrophenyl esters followed by condensation with taurine. 7-N-Acetylglucosaminides of ursodeoxycholates were prepared in a similar fashion. The convenient synthesis of 3-N-acetylglucosaminides of unconjugated bile acids is also described.
