| titleOfInvention | Derivative of a kind of steroid compound and preparation method thereof |
| abstract | The invention provides a derivative of a steroid compound and a preparation method thereof, and the structural formula of the derivative is: It is prepared by using dydrogesterone as a raw material, and reacting under the action of sodium chlorite and hydrogen peroxide under acidic conditions to generate derivatives of the steroid compound. By using the method of the present invention, derivatives of steroid compounds can be produced in a targeted manner, and the conversion rate is high and the yield is high. The compound can be used as a reference substance or standard substance for the analysis and determination of impurities in dydrogesterone or its preparation, and plays an important role in the quality control and process optimization of dydrogesterone. |
