  • Oxidation of unsaturated steroid ketones with hydrogen peroxide catalyzed by Fe(bpmen)(OTf)2. New methodology to access biologically active steroids by chemo-, and stereoselective processes
    作者:David Clemente-Tejeda、Alejandro López-Moreno、Francisco A. Bermejo
    DOI:10.1016/j.tet.2012.08.079
    日期:2012.11
    In this paper we describe a new environmentally friendly method to promote the oxidation of steroids. The chemo- and stereoselective aspects of the oxidation of conjugated enones, dienones, further unsaturated enones, estrone, and cholestane acetates were under study. The great facial stereoselectivity of the method has been shown on substrates 12, 14, and 18 improving some of the updated reported
    在本文中,我们描述了一种促进类固醇氧化的新型环保方法。正在研究共轭烯酮,二烯酮,其他不饱和烯酮,雌酮和胆甾烷乙酸酯的氧化反应的化学和立体选择性。 该方法的大的面部的立体选择性已显示在基片上12,14,和18改善了一些文献中报道的更新程序。与底物16的反应显示出C4–C5和C9–C11双键之间的竞争。C环周围的空间位阻通过形成烯丙醇17c激活C-12上烯丙基位置的C–H羟基化。 通过形成叔醇27,证明了C-5处的C–H活化在雄烷酮26的氧化反应中成功进行。
  • Approaches to the synthesis of triterpenoids. I. Methyl group migration to the 9β-position in steroids as a route to the cucurbitacins. A possible structural feature directing epoxide cleavage rearrangements
    作者:J. W. ApSimon、R. R. King、J. J. Rosenfeld
    DOI:10.1139/v69-321
    日期:1969.6.1
    steroidal 9α, 11α-epoxides has been studied in an attempt to induce migration of the C-10 methyl group to C-9. In the case of 9α,11α-epoxyandrost-4-ene-3,17-dione, cleavage with BF3 gas in benzene led to two major products. One of these was the required 3,11α-dihydroxy-9β-methylestra-1,3,5(10)-triene-17-one, thus leading to a novel class of steroids and possibly opening a route to the synthesis of compounds
    已经研究了 BF3 催化的一些甾体 9α、11α-环氧化物的裂解,试图诱导 C-10 甲基迁移到 C-9。在 9α,11α-epoxyandrost-4-ene-3,17-dione 的情况下,用 BF3 气体在苯中裂解产生两种主要产物。其中之一是所需的 3,11α-dihydroxy-9β-methylestra-1,3,5(10)-triene-17-one,从而产生一类新的类固醇,并可能开辟合成化合物的途径葫芦素类。另一个主要产品是 11α-羟基-9β-雄激素-4,8(14)-二烯-3,17-二酮。从其他环氧化物重排的研究中提出了一种可能的结构特征,将重排途径引导至这些材料,并在文献中有所报道。
  • Photochemical 6β-hydroxylation of 11β-hydroxy-4-androstene-3,17-dione
    作者:Alexander Kasal、Jorga Smolíková
    DOI:10.1135/cccc19842932

    The utilisability of the photochemical oxygenation of Δ3,5-enol ethers of the type III is limited in 11β-hydroxy derivatives which under the conditions of enol-etherification undergo dehydration to a considerable extent. A method for the protection of the 11β-hydroxy group in the form of a 11-keto group has been elaborated; after the enol-etherification the keto group can be reduced back to the 11β-hydroxy group.

    照片化学氧化Δ3,5-烯醇醚类型III的可利用性在11β-羟基衍生物中受到限制,在烯醇醚化条件下会发生脱水反应。已经制定了一种保护11β-羟基团的方法,以11-酮基团的形式进行保护;在烯醇醚化后,酮基团可以还原为11β-羟基团。
  • Oxidation of alkenes with non-heme iron complexes: suitability as an organic synthetic method
    作者:David Clemente-Tejeda、Francisco A. Bermejo
    DOI:10.1016/j.tet.2014.10.037
    日期:2014.12
    In the course of a preliminary study to determine the preparative value and the synthetic applications of the non-heme iron(II) complexes Fe(bpmen)(OTf)(2) and Fe(tpa)(OTf)(2), in particular the oxidation of alkenes by using hydrogen peroxide as the terminal oxidant, we have found significant differences in catalyst behavior. After several attempts it was clear that the preparative relevance of the oxidation processes was linked to the concentration of the catalyst and optimal results were obtained when the concentration value was 5 mol %. At that concentration, the Fe(bpmen)(OTf)(2) catalyst mostly gave rise to mixtures of the epoxide and the trans-dihydroxylation products formed by water-assisted hydrolytic cleavage of the epoxides. Furthermore, the use of the tripodal ligand tpa led to cis dihydroxylation products. When deactivated olefins were used as substrates for the oxidation reaction, the cis-diols were obtained exclusively, although with modest conversions, regardless of the catalyst used.
