METHOD OF PRODUCING 16α, 17α-CYCLOHEXANOPREGN-5-EN-3β-OL-20-ONE ACETATE Russian patent published in 2013 - IPC C07J53/00

Abstract RU 2495047 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 16α, 17α-cyclohexanopregn-5-en-3β-ol-20-one acetate of formula I , by hydrogenating 16α, 17α-cyclohex-3',4'-enopregn-5-en-3β-ol-20-one acetate in the medium of a polar organic solvent in the presence of a palladium catalyst on a support made from highly porous high-strength material based on the gamma-form of aluminium oxide, on which palladium is deposited in amount of 0.2-5%; the process is carried out at hydrogen pressure of 2-10 atm.

EFFECT: simple and considerably shorter duration of the process.
