    在微波辅助下,2-氰乙酰胺与芳香醛发生非催化缩合反应,并与丙烯酰胺发生由烯酸酯介导的迈克尔式加成反应,随后发生氧化环化反应,从而以良好至极佳的收率生成 2-吡啶酮。不对称酮会产生两种烯醇异构体,因此丁-2-酮和戊-2-酮的热力学和动力学产物已被分离出来并完全定性。

  • Cascade Synthesis of 2-Cyanoacrylamides through Deacetalization and/or Knoevenagel Condensation followed by Selective Monohydration of Acetals and Aldehydes over Solid Acid Ferrites
    作者:Sumit B. Kamble、Chandrashekhar V. Rode
    DOI:10.1002/cctc.201600426
    日期:2016.8.22
    involving deacetalization and/or Knoevenagel condensation followed by selective monohydration of nitriles starting from acetals (5) and aldehydes (2) with malononitrile (3). A series of aldehydes, dimethyl and diethyl acetals, along with some heterocyclic aldehydes were successfully transformed to 2‐cyanoacrylamides with >95 % yields. TEM images confirmed the coating of the PVP over nanosized Fe3O4
    提出了一种新的生物活性2-氰基丙烯酰胺级联合成的方案(1)。该反应在回流条件下,在AcOH-H 2 O介质中,通过一种新型的可磁性回收的固体酸复合物进行,该复合物是氧化铁,聚(乙烯基吡咯烷酮)和磷钨酸(Fe 3 O 4 / PVP-PWA)。通过单中心布朗斯台德酸催化的级联反应(包括脱缩醛和/或Knoevenagel缩合反应,然后由乙缩醛(5)和醛(2)与丙二腈(3)选择性地单水合腈),可以促进这种转化。)。一系列醛,二甲基和二乙基乙缩醛以及一些杂环醛已成功转化为2-氰基丙烯酰胺,收率> 95%。TEM图像证实了PVP在纳米Fe 3 O 4上的涂层。NOESY实验证明了2-苄叉基丙二腈(4)立体选择性单水合为E异构体。由于使用了缩醛和醛,因此该催化剂具有磁性,因此可以有效地循环使用七次。

    日期:——
    efficient synthesis of biologically active (E)-2-cyanoacrylamides and 3-substituted azetidine-2,4-diones has been reported with 64–94% yields under metal-free conditions. The reaction proceeds through sequential Knoevenagel condensation/stereoselective in situ monohydration of nitrile or C–N cyclization protocol in one-pot. The attractive features of this tandem process are moderate reaction conditions

  • Arylcyanoacrylamides as inhibitors of the Dengue and West Nile virus proteases
    作者:Christoph Nitsche、Christian Steuer、Christian D. Klein
    DOI:10.1016/j.bmc.2011.10.061
    日期:2011.12
    The 3-aryl-2-cyanoacrylamide scaffold was designed as core pharmacophore for inhibitors of the Dengue and West Nile virus serine proteases (NS2B-NS3). A total of 86 analogs was prepared to study the structure-activity relationships in detail. Thereby, it turned out that the electron density of the aryl moiety and the central double bond have a crucial influence on the activity of the compounds, whereas the influence of substituents of the amide residue is less relevant. The para-hydroxy substituted analog was found to be the most potent inhibitor in this series with a K(i)-value of 35.7 mu M at the Dengue and 44.6 mu M at the West Nile virus protease. The aprotinin competition assay demonstrates a direct interaction of the inhibitor molecule with active centre of the Dengue virus protease. The target selectivity was studied in a counterscreen with thrombin and found to be 2.8:1 in favor of DEN protease and 2.3:1 in favor of WNV protease, respectively. (C) 2011 Elsevier Ltd.
