Summary:1. Field of the Invention Steroids containing a cyclohexene moiety are efficiently oxidized to the corresponding , -unsaturated ketone using copper iodide and t-butyl hydroperoxide. A steroid compound containing the , -unsaturated ketone structure is efficiently converted to the corresponding vicinal diol using a hydroborating reagent followed by oxidative workup, e.g., borane followed by sodium perborate. Benzoyl and substituted benzoyls are superior protecting groups for hydroxyl groups present in the compounds.
