| titleOfInvention | PROCESS FOR PREPARING 3-CARBOXY-3,4-SECO-STEROIDS |
| abstract | Microbial conversion of C & ind21! Steroids produces 3-carboxy-3,4-seco-steroids. In a culture of Gymnoascus reesii in growing or quiescent culture, the starting steroid is added in an organic solvent under defined growth and pH conditions. After completion of the fermentation, the culture medium is acidified. The formed products are extracted with a suitable solvent. The acid residue obtained after separation with sodium carbonate solution is purified by column chromatography and, if appropriate after recrystallization, pure 3-carboxy-4-oxo-3,4-seco-5Al-pregnan-20-one and / or 3-carboxy-3,4-seco 5Alpha-pregnan-4-ol-20-one. |
