| titleOfInvention | A kind of preparation method of ergosterol or its derivative |
| abstract | The invention discloses a preparation method of ergosterol or a derivative thereof, which is simple and easy to implement. The nucleophilic reaction of the 22-position carbonyl of the core nucleus of ergosterol is carried out by using a nucleophile with a unique structure, which improves the selectivity of the reaction and can greatly improve the The preparation yield of ergosterol or its derivatives; at the same time, by optimizing the base and solvent in the nucleophilic reaction, adding crown ethers can further greatly improve the E/Z ratio, which provides a new method for the preparation of ergosterol or its derivatives. well established synthetic route. |
