    octane (DABCO)-catalyzed Knoevenagel condensation reactions, which showed better catalytic activity compared to other ionic liquid (IL) that had no hydroxyl group attached to the IL scaffold. The effect of hydrogen bond formation between the hydroxyl group of [HyEtPy]Cl and the carbonyl group of aldehyde played an important role in the Knoevenagel condensation reaction. In the [HyEtPy]Cl–H2O–DABCO
    合成并探索了N -(2-Hydroxy-ethyl)-pyridinium chloride ([HyEtPy]Cl) 作为 1,4-二氮杂双环 [2.2.2] 辛烷 (DABCO) 催化的 Knoevenagel 缩合反应的新型促进剂。与没有羟基连接到 IL 支架上的其他离子液体 (IL) 相比的催化活性。[HyEtPy]Cl的羟基与醛的羰基之间形成氢键的作用在Knoevenagel缩合反应中起重要作用。在 [HyEtPy]Cl–H 2在O-DABCO复合体系中,Knoevenagel缩合反应进行得平稳、干净,在所有考察的情况下,相应的Knoevenagel缩合产物均以良好至优异的收率获得。该协议提供了一种通用的溶剂-催化剂系统,具有生态友好、易于处理和离子液体方便重复使用等显着优势。

    A new, fast and straightforward method for the one-pot reaction of aromatic and aliphatic aldehydes and dialdehydes with ethyl cyanoacetate and cyanogen bromide was developed to afford stereoselectively diethyl 1,2-dicyano-3-alkyl/arylcyclopropane-1,2-dicarboxylate in excellent yields and short reaction time (about 5 s). The structures were characterized by IR, 1H NMR and 13C NMR spectroscopy. The reaction mechanism was discussed.

  • Simple, Efficient, and Green Method for Synthesis of Trisubstituted Electrophilic Alkenes Using Lipase as a Biocatalyst
    作者:Bhushan Nanasaheb Borse、Sanjeev Ramchandra Shukla、Yogesh Ashok Sonawane
    DOI:10.1080/00397911.2010.525334
    日期:2012.2.1
    Abstract A simple and efficient Knoevenagel condensation method for the synthesis of trisubstituted electrophilic alkenes was developed using lipase as a biocatalyst. Knoevenagel condensation was performed using the conventional method and using lipases (Aspergillus oryzae or Rhizopus oryzae) as biocatalysts, and reaction time, reaction temperature, yield, and recyclability were compared. Using a lipase
    摘要 以脂肪酶生物催化剂,开发了一种简单高效的Knoevenagel缩合方法,用于合成三取代亲电烯烃。Knoevenagel缩合采用常规方法,以脂肪酶(米曲霉或米根霉)为生物催化剂,比较反应时间、反应温度、收率和可回收性。使用脂肪酶作为生物催化剂消除了对哌啶吡啶等碱的需求。多种芳香醛和酮容易与活性亚甲基化合物缩合。后处理程序也非常简单,反应产率在75%到95%之间。两种生物催化剂都有效地循环了四次,产品的产率没有显着降低。脂肪酶显着的催化活性和可重复使用性扩大了其在 Knoevenagel 缩合中的适用性,在合成三取代的亲电烯烃时具有良好的收率。图形概要

    作者:Kaushik Naskar、Suvendu Maity、Himadri Sekhar Maity、Chittaranjan Sinha
    DOI:10.3390/molecules26175296
    日期:——

    [Cu(CPA)(BDC)]n (CPA = 4-(Chloro-phenyl)-pyridin-4-ylmethylene-amine; BDC = 1,4-benzenedicarboxylate) has been synthesized and structurally characterized by single crystal X-Ray diffraction measurement. The structural studies establish the copper (II) containing 2D sheet with (4,4) square grid structure. The square grid lengths are 10.775 and 10.769 Å. Thermal stability is assessed by TGA, and subsequent PXRD data establish the crystallinity. The surface morphology is evaluated by FE-SEM. The N2 adsorption−desorption analysis demonstrates the mesoporous feature (∼6.95 nm) of the Cu-MOF. This porous grid serves as heterogeneous green catalyst with superficial recyclability and thermal stability and facilitates organic transformations efficiently such as, Click and Knoevenagel reactions in the aqueous methanolic medium.
