  • A novel bi-functional surfactant-based paramagnetic deep-eutectic catalyst for improved benzoin condensation and multi-component synthesis of pyrrole derivatives
    作者:Fatemeh Tamaddon、SeydEhsan Tadayonfar

    日期:2019.4
    for improved benzoin condensation and three-component synthesis of substituted pyrroles with the highest turnover number (TON) and turnover frequency (TOF) that ever reported for this purpose. The superior activity of MGSFe is due to its amphiphile properties, the synergistic effects between GS2+ and 2FeCl4− as hydrogen-bond-donor and magnetic hydrogen-bond-acceptor components of this novel magneto-responsive
    通过制备的阳离子双基表面活性剂(GS)与两摩尔FeCl的优化反应,合成了一种新型的专业磁性表面活性剂基深共熔(DE)和粘胶液化催化剂(GS 2 + ·2FeCl 4,MGSFe)。3 ·6小时2O. GS和MGSFe的结构通过NMR,FT-IR,紫外可见光,CHN,pH,表面张力(ᵞ)和振动样品磁强度(VSM)分析进行了表征。MGSFe是> 50°C时的高粘稠棕褐色液体,已成功测试作为高活性顺磁性催化剂,可改善安息香的缩合反应和三组分合成取代吡咯的最高周转数(TON)和周转频率(TOF) )为此目的进行了报道。MGSFe的优良的活性是由于其两亲性质,GS之间的协同效应2+和2FeCl 4 -作为这种新颖的磁响应DE的氢键供体和磁性氢键受体组分,即使在合成吡咯的四个结果循环中,其重用性也不会丧失活性。这种基于GS的磁性DE可用作油溶混性添加剂,污染物吸附剂和目标物质毒物的生物材料载体。

    pyrroles were synthesized via three-component condensation reaction of benzoin derivatives, 1,3-dicarbonyl compounds, and ammonium acetate using acidic Al2O3 as an efficient and reusable heterogeneous catalyst in refluxing ethanol in high yields. Also, acidic alumina was catalyzed 1,4-dihydro-tetraarylpyrazines by the condensation reaction of benzoins and ammonium acetate in refluxing ethanol in high
    摘要利用酸性Al 2 O 3作为高效可重复使用的多相催化剂,通过苯偶姻衍生物,1,3-二羰基化合物和乙酸铵的三组分缩合反应,合成了一些新的2,3,4,5-四取代的吡咯。高产。同样,通过苯甲酸酯和乙酸铵在回流的乙醇中的缩合反应,可以高产率地催化酸性氧化铝催化1,4-二氢-四芳基吡嗪。当用于连续反应运行时,氧化铝显示出几乎相同的效率。 图形概要酸性氧化铝用作非均相酸性催化剂,用于在回流的乙醇中合成四取代的吡咯。催化剂可以循环使用几次。

    日期:2012.4
    Molybdate sulfuric acid (MSA) has been found as an efficient and reusable solid acid catalyst for the synthesis of new 2,3,4,5-tetrasubstituted pyrroles via a novel [2+2+1] strategy. Thus, one-pot three-component reaction of benzoin derivatives, 1,3-dicarbonyls, and ammonium acetate afforded the desired products in high yield under solvent-free conditions.
    硫酸(MSA)已被发现是一种有效且可重复使用的固体酸催化剂,可通过新颖的[2 + 2 + 1]策略合成新的2,3,4,5-四取代的吡咯。因此,安息香生物,1,3-二羰基化合物和乙酸铵的一锅三组分反应在无溶剂条件下以高收率提供了所需的产物。
  • Divergent copper-catalyzed syntheses of 3-carboxylpyrroles and 3-cyanofurans from <i>O</i>-acetyl oximes and β-ketoesters/nitriles
    作者:Wilfrido E. Almaraz-Ortiz、Aldahir Ramos Orea、Oscar Casadiego-Díaz、Agustín Reyes-Salgado、Arturo Mejía-Galindo、Rubén O. Torres-Ochoa

    The reaction between O-acetyl oximes and β-ketoesters/nitriles catalyzed by copper generated polysubstituted pyrroles and furans, respectively, under redox–neutral reaction conditions. Using this protocol, pyrroles or furans could be obtained simply by choosing an appropriate active methylene compound. Although both transformations occur essentially under the same reaction conditions, control experiments
    在氧化还原中性反应条件下,催化的O-乙酰和 β-酮酯/腈之间的反应分别生成多取代的吡咯呋喃。使用该协议,只需选择适当的活性亚甲基化合物即可获得吡咯呋喃。尽管这两种转化基本上发生在相同的反应条件下,但对照实验表明它们遵循不同的机制途径。
  • Improved Catalyst-Free Synthesis of Pyrrole Derivatives in Aqueous Media
    作者:Fatemeh Tamaddon、Farideh Amirpoor
    DOI:10.1055/s-0033-1339294
    日期:——
    An improved catalyst-free, three-component reaction of ammonium acetate, 1,3-dicarbonyl compounds, and aromatic a-hydroxycarbonyl compounds has been carried out in water-ethanol (50:50) under reflux conditions. The improvement of yield in this aqueous medium is attributed to a combination of increased association of the reactants by hydrophobic interactions and precipitation of the product during the reaction. This operationally simple procedure is less laborious and provides a better scope and chemoselectivity than previously reported procedures.
