This paper describes a method for the chemical synthesis of 7alpha,12alpha-dihydroxy-4-cholesten-3-one (1a) and its biological precursor, 7alpha-hydroxy-4-cholesten-3-one (1b), both of which are key intermediates in the major pathway of bile acidbiosynthesis from cholesterol. The principal reactions involved were (1) building of the cholesterol (iso-octane) side chain by 3-carbon elongation of the
