| titleOfInvention | A kind of 16-beta-methylpregnene steroid hormone intermediate and preparation method thereof |
| abstract | The invention relates to a 16-beta-methylpregnene steroid hormone intermediate and a preparation method thereof. The intermediate has a structure represented by formula (I). The invention uses mold fermented product as raw material, and adopts three steps of ketal protection, Grignard reaction and hydrolysis reaction to obtain the intermediate. The intermediate can be used for synthesizing betamethasone steroid hormone bulk drug, and using this substance as an intermediate can greatly shorten the synthesis route of betamethasone, reduce costs, and reduce the discharge of "three wastes". |
