专利号:US-2005085452-A1 优先权日:2002-09-03 标 题:Process for the synthesis of pharmacologically active (z/e)-guggulsterones 发明人:GOKARAJU GANGA R; GOKARAJU RAMA R; GOTTUMUKKALA VENKATA S; SOMEPALLI VENKATESWARLU 摘要:The invention relates to an improved process for producing pharmacologically active synthetic stereoisomeric mixture of guggulsterones (4) in the three steps. The mixture of gugguisterones consists of Z-guggulsterone [4,17(20)-trans-pregnadiene-3,16-dione] and E-guggulsterone [4,17(20)-cis-pregnadiene-3,16-dione] and could be in any relative ratio. This improved process comprises (a) epoxidation of 16-dehydropregnanolone acetate (1) with hydrogen peroxide (b) reduction of the so obtained epoxide (2) with hydrazine hydrate and (c) oxidation of the diol (3).
