Abstract

Abstract A new method for the aromatization of ring A 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.
