| titleOfInvention | PROCESS FOR OBTAINING 16α,17α-CYCLOHEXANO-5α,6α-EPOXYPREGN-3β-OL-20-ONE ACETATE |
| abstract | The invention relates to the chemistry of natural and physiologically active substances and especially, to a process for obtaining an intermediate product in the synthesis of steroid hormones of the pregnane series. The process for obtaining 16α,17α-cyclohexano-5α,6α-epoxypregn-3β-ol-20-one acetate comprises treatment of 16α,17α-cyclohexanopregn-5-en-3β-ol-20-one acetate with an organic peracid in the medium of a polar organic solvent, its particular characteristic is that p- carbomethoxyperbenzoic acid is used as the organic peracid, and the process is carried out at the temperature of 25 - 30°C and at the molar ratio of 16α,17α-cyclohexanopregn-5-en-3β-ol- 20-one acetate : p-carbomethoxyperbenzoic acid 1 : 1.1 - 1.5. The technical result is the security and simplifying of the proposed process and the improved specificity of the process for providing generation of a a-isomer of the desired product; the process can be used in the manufacture of an intermediate product for the synthesis of. steroid hormones of the pregnane series, which represent valuable hormonal products used in medicine. |
