Process for the production of 6, 7 - dihydroxy steroid compounds by allylic oxidation of steroid - 5 - ene compounds to steroid - 5 - ene - 7 - one compounds followed by hydroboration and oxidation and intermediates of this process |
| abstract |
Steroids containing a cyclohexene moiety are efficiently oxidized to the corresponding .alpha., .beta.-unsaturated ketone using copper iodide and t-butyl hydroperoxide. A steroid compound containing the .alpha., .beta.-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. |
