  • SmCl<sub>3</sub>-Catalyzed <i>C-</i>Acylation of 1,3-Dicarbonyl Compounds and Malononitrile
    作者:Quansheng Shen、Wen Huang、Jialiang Wang、Xigeng Zhou
    DOI:10.1021/ol701961z
    日期:2007.10.1
    A recyclable, convenient, and efficient catalytic system for C-acylation of 1,3-dicarbonyl compounds and malononitrile with acid chlorides has been developed, giving moderate to excellent yields under mild conditions. This is the first catalytic example of such reactions. In addition, by applying this protocol as the key step, 3,5-disubstituted-1H-pyrazole-4-carboxylate can easily be synthesized in
    已开发出一种可回收,方便且有效的催化体系,用于用酰氯对1,3-二羰基化合物和丙二腈进行C-酰化,在温和条件下产生中等至极好的收率。这是这种反应的第一个催化实例。另外,通过将该方案用作关键步骤,可以轻松地以一锅法高收率合成3,5-二取代-1H-吡唑-4-羧酸酯。
  • Pd-catalyzed carbonylation for the construction of tertiary and quaternary carbon centers with sp3 carbon partners

    The first examples of a Pd-catalyzed carbonylation of aryl boronic acids with sp3 carbon partners are presented. Various boronic acids were shown to react with 1,3-diesters and 1,3-diketones to afford structurally unique carbonyl compounds. By employing 2-substituted 1,3-diesters, synthetically-challenging quaternary carbon centres were accessed. In total, 42 examples of aryl carbonyl compounds were prepared in moderate to good yields. The catalytic system features the use of a bidentated phosphine ligand and a relatively low CO pressure (5 atm), providing an easy, alternative method for the preparation of triketones.
    展示了使用Pd催化的芳基硼酸与sp3碳伙伴进行羰基化的首个示例。各种硼酸与1,3-二酯和1,3-二酮反应,生成了结构独特的羰基化合物。通过使用2-取代的1,3-二酯,成功获得了合成上具有挑战性的四级碳中心。总共合成了42种芳基羰基化合物,产率中等到良好。该催化系统采用了双联磷配体和相对较低的CO压力(5个大气压),为合成三酮提供了一种简单的替代方法。
  • Enol elimination reactions. Part IV. Some improvements to the synthesis of conjugated acetylenic acids
    作者:Ian Fleming、C. R. Owen
    DOI:10.1039/j39710002013
    日期:——
    avoided altogether by using arenesulphonic anhydrides as sulphonating agents. The result is that the synthetic sequence: acylmalonate → enol sulphonate → acetylenic acid is now a useful one for the synthesis of conjugated acetylenic acids. For some purposes the use of t-butyl esters in place of ethyl esters has advantages.
    酰基丙二酸酯的烯醇盐(2)与戊烯磺酰卤的反应产生的烯醇磺酸盐收率低,部分原因是竞争性卤化产生了α-卤代酮(6)。卤化是可逆的,并且由于逆反应导致重新建立​​原始的磺化条件,因此可以由α-卤代酮与戊二酸根离子的反应制备烯醇磺酸盐。该反应是Perkow反应的硫当量,但没有制备价值。通过使用芳烃磺酸酐作为磺化剂可以完全避免卤化反应。结果是合成顺序为:酰基丙二酸酯→烯醇磺酸盐→乙炔酸现在是用于合成共轭乙炔酸的有用的一种。出于某些目的,使用叔丁基酯代替乙基酯具有优势。

    combinations of IonWorks and Q-patch assays successfully identified the nicotinamide derivative 4. Its increasing decay time constant (tau) of Nav1.1 currents at 0.03 μM along with significant selectivity against Nav1.2, Nav1.5, and Nav1.6 and acceptable brain exposure in mice was observed. Compound 4 is a promising Nav1.1 activator that can be used to analyze pathophysiological functions of the Nav1
    电压门控钠通道Nav1.1主要在小白蛋白阳性快速加标中间神经元中表达,并与Dravet综合征遗传相关。从高通量筛选命中的异恶唑衍生物5开始,通过结合IonWorks和Q-patch分析对5进行修饰,成功鉴定出烟酰胺衍生物4。其Nav1.1电流在0.03μM时的增加的衰减时间常数(tau)以及显着的选择性小鼠对Nav1.2,Nav1.5和Nav1.6的抵抗力和可接受的大脑暴露情况都可以观察到。化合物4是一种很有前途的Nav1.1激活剂,可用于分析Nav1.1通道的病理生理功能,以治疗各种中枢神经系统疾病。
  • Substitution controlled aryne insertion: synthesis of diarylmethane/chromones
    作者:Jadhav Rahul Dhanaji、Polasani Samatha、Silver Raju、Prathama S. Mainkar、Raju Adepu、Srivari Chandrasekhar
    DOI:10.1039/d2cc05992d
    日期:——
    Aryne insertion reaction with 2-aroyl malonates/cyanoesters lead to the formation of diarylmethane or chromones depending on the substitution on the aryne ring. The presence of an electronegative atom at the ortho position of arynes generates chromones, whereas other arynes lead to the formation of diarylmethanes, via a cascade double aryne insertion.
