| titleOfInvention | Process for the preparation of 3-beta, 7-beta-dihydroxy-delta-5 steroids |
| abstract | A process for preparing a 3 beta ,7 beta -dihydroxy- DELTA 5-steroid of the formula <IMAGE> wherein Q is <IMAGE> and R1 is hydrogen, trimethylacetyl, tert-butyldimethylsilyl, dimethyl-2-(3-methylbutyl)silyl or tribenzylsilyl, comprises fermenting a 3 beta -hydroxy- DELTA 5-steroid of the formula <IMAGE> wherein Q is as defined above, and R2 is hydrogen or alkanoyl of 2-6 carbon atoms, with a culture of Botryodiplodia malorum to obtain the corresponding 3 beta ,7 beta -dihydroxy- DELTA 5-steroid; and, optionally, reacting the resultant product with trimethylacetic anhydride, tert-butyldimethylsilyl chloride, dimethyl-2-(3-methylbutyl)silyl chloride, or tribenzylsilyl chloride. |
