title: A convenient synthesis of 3-keto bile acids by selective oxidation of bile acids with silver carbonate-Celite.
abstract: A number of 3-keto bile acids were synthesized by the selective oxidation of bile acid methyl esters with silver carbonate-Celite in refluxing toluene. The pure 3-keto bile acids were isolated simply by filtering the reaction mixture and concentrating the filtrate. The relation of the bile acid structure to the oxidation rate is also discussed.
