in androsta-1,4-diene-3,17-dione, available from sterols by means of the microbiological degradation of the side chain, was developed. The method consists of the reduction of androsta-1,4-diene-3,17-dione to the corresponding dienediol followed by double C,O-deprotonation of ring A, accompanied by expulsion of the 19-methyl group and formation of estradiol in a high yield.
开发了一种新方法,用于通过侧链的微生物降解从甾醇中获得的 androsta-1,4-diene-3,17-dione 中的 A 环芳构化。该方法包括将 androsta-1,4-diene-3,17-dione 还原为相应的二烯二醇,然后对 A 环进行双 C,O-去质子化,同时排出 19-甲基并在其中形成雌二醇。高产。
