    the first time from a five-component Fe3O4@TDSN-Bi(III)-catalyzed reaction of aryl aldehydes, aryl amines, and ethyl acetoacetate. This magnetically separable catalyst enabled the selective incorporation of two different aryl amines or two different aryl aldehydes into the product, and provided excellent yields, short reaction times, mild reaction conditions, satisfactory catalyst recyclability, and

    Moreover, some of themhavebeenfoundtobeusefulasinhibitorsofaminopeptidaseandalpha-glucosidase. Numerous recent methods reported for the synthesis of highly substituted piperidines use various catalytic systems such as bismuth nitrate, molecular iodine, bromodimethyl-sulfonium bromide (BDMS), tetra(n-butyl)ammonium tribromide (TBATB), InCl3, 21 CAN, ZrOCl2.8H2O, 23 picric acid, ionic liquids, ZrCl4, 26
    磁性纳米粒子在催化领域的应用已成为一个有用的研究领域。功能化磁性纳米粒子 (MNPs) 已被用于有机合成,在氧化、氢化、C-C 偶联、烯烃的二羟基化和胺化反应中显示出优异的催化活性。目前,很多注意力都集中在通过在其周围涂覆二氧化硅壳来合成磁性核壳结构。MNPs 是一种高效、容易获得的多相催化剂,具有出色的稳定性。大多数负载型催化剂通过过滤或离心分离,这可能导致催化剂的损失。为了克服这种可能的复杂性,MNP 已成为有效的支持物,因为它们可以通过外部永磁体与反应混合物分离。功能化哌啶及其衍生物是一类非常重要的杂环化合物,因为它们具有多种生物活性。许多带有这种杂环单元的化合物已显示出多种有趣的生物活性,如抗炎、抗氧化、抗菌、抗疟疾和抗结核特性。此外,已发现其中一些可用作氨基肽酶和α-葡萄糖苷酶的抑制剂。最近报道的许多合成高取代哌啶的方法使用各种催化系统,如硝酸铋、分子碘、溴化二甲基溴化锍 (BDMS)、四(正丁基)三溴化铵

  • Synthesis, characterization and first application of keggin-type heteropoly acids supported on silica coated NiFe<sub>2</sub>O<sub>4</sub>as novel magnetically catalysts for the synthesis of tetrahydropyridines

    In this study, two heteroploly acids with Keggin structures (phosphotungestic acid (PWA) and phosphomolybdic acid (PMA)) have been supported on silica coated nickel ferrite nanoparticles (NiFe2O4@SiO2). The synthesized catalysts were characterized by several methods (FT-IR, SEM, TEM, VSM, XRD, BET and ICP-AES), and the catalytic activities of these new and magnetic catalysts in synthesis of tetrahydropyridine derivatives have been investigated. These new catalysts showed that they can carry out reactions at room temperature in a short time and under solvent-free conditions. Moreover, the obtained results indicated that PWA supported NiFe2O4@SiO2 is a stronger acid than PMA to run these reactions. More importantly, the catalysts were easily isolated from the reaction mixture by a magnetic bar and reused at least five times without significant degradation in their activities.
    在这项研究中,采用Keggin结构的两种异源多酸(磷钨酸(PWA)和磷钼酸(PMA))被负载在涂有二氧化硅的镍铁氧体纳米颗粒(NiFe2O4@SiO2)上。合成的催化剂采用多种方法进行表征(FT-IR、SEM、TEM、VSM、XRD、BET和ICP-AES),并研究了这些新型磁性催化剂在合成四氢吡啶衍生物中的催化活性。这些新催化剂表明,它们能够在室温下、短时间内及无溶剂条件下进行反应。此外,获得的结果表明,负载PWA的NiFe2O4@SiO2在进行这些反应时比PMA具有更强的酸性。更重要的是,催化剂可以通过磁棒轻松从反应混合物中分离出来,并在未显著降低活性的情况下重复使用至少五次。
