  • Water Soluble Steroids with Catalytic Substituents II. Synthesis of 3β-(4(5)-Imidazolyl)-5α-androstane-11β, 17β,-diamine and Comparison of its Catalytic Properties with Those of 17β-(4(5)-Imidazolyl)-5α-androstane-3β, 11β-diamine

    3β-(4(5)-Imidazolyl)-5α-androstane-11β,17β-diamine, 15, has been synthesized in a multistep process from adrenosterone, 2, starting with lithium ammonia reduction to give 11α,17β-dihydroxy-5α-androstan-3-one, 3, which was converted to its diacetate, 4. Ethynylation at the 3 keto group gave the ethynyl triol 5, purified as its11,17-diacetate 6. Acid catalyzed rearrangement of 6 gave 3-acetyl-5α-androst-2-ene-11α,17β-diol diacetate, 7. This was hydrogenated, and then subjected to base catalyzed hydrolysis and equilibration to give crystalline 3β-acetyl-5α-androstane-11α,17β-diol, 9, which was converted to 3β-acetoxyacetyl-5α-androstane-11α,17β-diol, 10, using lead tetraacetate. After hydrolysis to the triol, 11, the Weidenhagen reaction led to formation of 3β-imidazolyl-5α-androstane-11α,17β-diol, 12. Finally oxidation to the dione, 13, formation of the dioxime, 14, and hydrogénation give 15. As expected 15 is a better catalyst than 17β-(4(5)-imidazolyl-5α-androstane-3β,11β-diamine, 1, for the hydrolysis of aryl esters of acids with hydrophobic substituents, but the effect is small. With 1 there is a marked electrostatic rate enhancement or retardation when charged groups are present on the aryl esters; this effect is much smaller for 15.

    3β-(4(5)-咪唑基)-5α-雄烷-11β,17β-二胺,15,是从腺酮,2,经过多步合成的,首先进行锂氨还原得到11α,17β-二羟基-5α-雄甾-3-酮,3,然后转化为其二乙酸酯,4。在3酮基上进行乙炔基化得到乙炔三醇5,纯化为其11,17-二乙酸酯6。酸催化6的重排得到3-乙酰基-5α-雄烷-2-烯-11α,17β-二醇二乙酸酯,7。这经过氢化,然后经过碱催化水解和平衡得到结晶的3β-乙酰基-5α-雄烷-11α,17β-二醇,9,它被转化为3β-乙酰氧乙酰-5α-雄烷-11α,17β-二醇,10,使用四乙酸铅。水解为三醇后,11,魏登哈根反应导致形成3β-咪唑基-5α-雄烷-11α,17β-二醇,12。最后氧化为二酮,13,形成二肟,14,和氢化得到15。如预期的那样,15比17β-(4(5)-咪唑基-5α-雄烷-3β,11β-二胺,1,更好地催化含疏水取代基的芳基酯的水解,但效果很小。对于1,当芳基酯上存在带电基团时,会出现明显的静电速率增强或减缓;而对于15,这种效应要小得多。

    摘要 真菌 Cephalosporium aphidicola 已显示羟基化 5α,13α-androstan-3,17-dione 和 C-1α 和 C-7α 位置的 3β-醇,而正常 13β-甲基系列中的相应化合物在 C-11α 和 C-14α 位被羟基化。两个系列均在 5α 位被羟基化。轴向 3α-醇与赤道 3β-差向异构体发生了一些差向异构化。© 1997 Elsevier Science Ltd. 版权所有

    a rare reduction to 11α-hydroxy-5β-dihydrotestosterone. The experiments have demonstrated that the Baeyer–Villiger monooxygenase produced by the strain catalyzes solely oxidation of C-20 or C-17 ketones with 11α-hydroxyl group. 17-Oxo steroids, beside the 11α-hydroxylation and Baeyer–Villiger oxidation, also underwent reduction to 17β-alcohols; activity of 17β-hydroxysteroid dehydrogenase (17β-HSD)
    本文首次证明了最常用的全细胞生物催化剂球孢白僵菌(Beauveria bassiana)将一系列17-氧代甾族底物(表雄酮,脱氢表雄酮,雄烯二酮)转化为11α-羟基-17a-氧杂d-均一-17种产物,按以下反应顺序进行:11α-羟基化和随后的Baeyer-Villiger氧化成环D内酯。孕酮代谢第一阶段的产物11α-羟基孕酮沿两种途径进一步转化:羟基化为6β,11α-二羟基孕酮或17β-乙酰基链降解,从而导致11α-羟基睾酮(底物的主要代谢产物)。11α-羟基睾丸激素的一部分罕见地还原为11α-羟基-5β-二氢睾丸激素。实验表明,该菌株产生的Baeyer-Villiger单加氧酶仅催化带有11α-羟基的C-20或C-17酮的氧化。除11α-羟基化和Baeyer-Villiger氧化外,17-氧代类固醇也被还原为17β-醇。17β羟基类固醇脱氢酶(17β-HSD)的活性对所形成的环-的量显著冲击d
  • New Preparation Methods for Organic–Inorganic Polymer Hybrids
    作者:Yoshiki Chujo、Ryo Tamaki
    DOI:10.1557/mrs2001.92
    日期:2001.5

    Nano-ordered composite materials consisting of organic polymers and inorganic compounds have been attracting attention for their use in creating high-performance or high-functionality polymeric materials. The term “polymer hybrid” describes blends of organic and inorganic components with molecular-level dispersions.

    由有机聚合物和无机化合物组成的纳米有序复合材料因其用于制造高性能或高功能聚合材料而受到关注。术语“聚合物混合物”描述了有机和无机成分的混合物,具有分子级分散。
  • The hydroxylation of Δ5-androstenes by Cephalosporium aphidicola
    作者:Caroline M Bensasson、James R Hanson、A.Christy Hunter
    DOI:10.1016/s0031-9422(98)00312-4
    日期:1998.12
    Whereas the major hydroxylation product of 3 beta-hydroxy-5 alpha-androstan-17-one by Cephalosporium aphidicola is the 11 alpha-alcohol, the presence of a Delta(5)-double bond in the substrate leads to nonstereospecific allylic hydroxylation at C-7. Hydroxylation at C-11 became a minor transformation and there was no detectable hydroxylation at C-14. (C) 1998 Elsevier Science Ltd. All rights reserved.
