  • Method for synthesizing 5beta, 6beta-epoxides of steroids by a highly beta-selective epoxidation of delta5-unsaturated steroids catalyzed by ketones

    A general, efficient, and environmentally friendly method is provided for producing mostly &bgr;-epoxides of &Dgr; 5 -unsaturated steroids using certain ketones as the catalyst along with an oxidizing agent, or by using certain dioxiranes. In another aspect of the invention, a method is provided for producing mostly 5&bgr;,6&bgr;-epoxides of steroids from &Dgr; 5 -unsaturated steroids having a substituent at the 3&agr;-position by an epoxidation reaction using a ketone along with an oxidizing agent under conditions effective to generate epoxides, or using a dioxirane under conditions effective to generate epoxides. A whole range of &Dgr; 5 -unsaturated steroids, bearing different functional groups such as hydroxy, carbonyl, acetyl or ketal group as well as different side chains, were conveniently converted to the corresponding synthetically and biologically interesting 5&bgr;,6&bgr;-epoxides with excellent &bgr;-selectivities and high yields.
    提供了一种通用、高效且环保的方法,用于利用某些酮作为催化剂以及氧化剂,或者使用某些二氧杂环丙烷,生产大部分为&Dgr; 5 -不饱和类固醇的&bgr;-环氧化物。在发明的另一个方面,提供了一种方法,通过使用酮以及氧化剂进行环氧化反应,或者在有效条件下使用二氧杂环丙烷,从3&agr;-位有取代基的&Dgr; 5 -不饱和类固醇中生产大部分为5&bgr;,6&bgr;-环氧化物。一整套带有不同官能团(如羟基、酮基、乙酰基或缩醛基)以及不同侧链的&Dgr; 5 -不饱和类固醇,方便地转化为相应的合成和生物学上有趣的5&bgr;,6&bgr;-环氧化物,具有优异的&bgr;-选择性和高产率。
  • Selective reactivity of 2-mercaptoethanol with 5β,6β-epoxide in steroids from Withania somnifera

    5beta,6beta-epoxy steroids isolated from Withania somnifera substituting the epoxide by a six-membered oxyethylene-2'-thio ring whereas it failed to show such reactivity on 6alpha,7alpha-epoxy withasteroids. The structure of the product has been elucidated by spectroscopic methods, especially applying extensive 2D NMR methods. The anticancer activity of withaferin A was lost in the reaction product indicating
    2-巯基乙醇选择性地与从Withania somnifera分离的5beta,6beta-环氧类固醇反应,用六元氧化乙烯-2'-硫代环取代环氧化物,而对6alpha,7alpha-环氧类固醇没有反应性。产物的结构已经通过光谱方法阐明,特别是应用了广泛的2D NMR方法。在反应产物中枯萎素A的抗癌活性丧失,表明其活性也与游离的5β,6β-环氧官能团有关。
