Abstract
Procedure for the obtaining of 3alfa, 7beta-dihydroxy-5-beta-colan-24-oic acid. It consists in the oxidation of the 3alfa, 7beta-dihydroxy-5-beta-colan-24oic acid to 3,7 dioxo-5-beta-colan-24-oico oxidization by an adequate oxidizer. Subsequently, a stereoselective reduction of the intermediate 3,7-dioxide derivative to obtain the desired product is possible. Oxidizing agents are used to use bromine or chlorine in alkaline medium, potassic dichromate chromium anoyidide or reagent of jones. The reaction is carried out in the presence of an inert solution, which suele to be acetone. The oxidation process has place at a temperature comprised between 20 and 25gc. This compound has pharmacological application and is used to decrease the litogenic index of the bilis. T (Machine-translation by Google Translate, not legally binding)
