Potential Bile Acid Metabolites. 7. 3,7,12-Trihydroxy-5β-cholanic Acids and Related Compounds
With this work, the complete set of the eight possible stereoisomeric (5β)-3,7,12-trihydroxy acids are now known and characterized.The key intermediates methyl 3α,7β-dihydroxy-12-oxo- and 3β,7β-dihydroxy-12-oxocholanate have been synthesized, and their reductions by tert-butylamine-borane complex and by NaBH4 are described.
