Chemical synthesis of 3 alpha,6 beta,7 alpha,12 beta- and 3 alpha,6 beta,7 beta,12 beta-tetrahydroxy-5 beta-cholan-24-oic acids is described. 3 alpha,12 beta-Dihydroxy-5 beta-chol-6-en-24-oic acid used as the starting material in the synthesis was prepared via oxidation of 3 alpha,12 alpha-dihydroxy-5 beta-chol-6-en-24-oic acid 3-hemisuccinate at C-12 followed by reduction with potassium/tertiary amyl
