Rapid preparation of tritium-labeled bile acids by enolic exchange on basic alumina containing tritiated water
When a 3-keto bile acid methyl ester was chromatographed on basic alumina inactivated with tritiated water, the enolic hydrogen atoms at C-2 and C-4 exchanged with tritium atoms. The 3H-labeled keto ester was reduced with borohydride, and the resultant mixture of 3α- and 3β-hydroxy epimers was resol...
