    Synthesis and fungicidal activity of 3,5-dichloropyrazin-2(1H)-one derivatives
    摘要:
    We synthesized a family of 3,5-dichloropyrazin-2(1H)-one derivatives and assessed their in vitro fungicidal activity against Candida albicans. Compounds 11 and 20 were most active against C. albicans and induced accumulation of reactive oxygen species in this pathogen. Using a genome-wide approach in the yeast Saccharomyces cerevisiae, we demonstrated that genes involved in vacuolar functionality and DNA-related functions play an important role in cellular mechanisms underlying the fungicidal activity of these compounds.

  • Ag<sup>+</sup>-Mediated Synthesis of Substituted Furo[2,3-<i>b</i>]pyrazines
    作者:Erik Van der Eycken、Denis Ermolat’ev、Vaibhav Mehta
    DOI:10.1055/s-2007-992358
    日期:——
    A highly efficient method for the preparation of trisubstituted furo[2,3-b]pyrazines has been developed. Sonogashira coupling reaction with the readily available 1-(4-methoxybenzyl)-3,5-dichloropyrazin-2(1H)-ones was followed by silver-catalyzed heteroannulation to provide the corresponding 2-chlorofuro[2,3-b]pyrazines in excellent yields. The latter were subjected to Suzuki or Buchwald-Hartwig coupling reaction for further decoration.
    开发了一种制备三取代呋喃并[2,3-b]吡嗪的高效方法。首先使用易于获得的1-(4-甲氧基苄基)-3,5-二氯吡嗪-2(1H)-酮进行Sonogashira偶联反应,随后通过银催化的杂环化作用,以优异的产率得到了相应的2-氯呋喃并[2,3-b]吡嗪。后者再通过Suzuki或Buchwald-Hartwig偶联反应进行进一步修饰。

    the synthesis of diversely substituted furo[2,3-b]pyrazines has been elaborated. The Ag+- or iodine-mediated electrophilic cyclization of readily generated 5-chloro-3-substituted ethynyl-1-(4-methoxybenzyl)-pyrazin-2(1H)-ones affords substituted furo[2,3-b]pyrazines, which undergo various palladium catalyzed reactions to generate a library of difficult to attain diversely substituted furo[2,3-b]pyrazines
    精心设计了一种高效的合成不同取代的呋喃并[2,3- b ]吡嗪的方法。易产生的5-氯-3-取代的乙炔基-1-(4-甲氧基苄基)-吡嗪-2(1 H)-酮的Ag +或碘介导的亲电环化反应提供了取代的呋喃[2,3- b ]吡嗪,它们经历各种钯催化的反应以生成难以获得不同取代的呋喃并[2,3- b ]吡嗪的文库。
  • Alkylation of 3,5-dichloro-2(1H)-pyrazinones using malonate esters
    作者:Nigam M. Mishra、Vsevolod A. Peshkov、Olga P. Pereshivko、Sachin G. Modha、Erik V. Van der Eycken

    日期:2012.8
    3-alkylation of 3,5-dichloro-2(1H)-pyrazinones with various malonate esters is described. The method constitutes a simple example of a C–C bond forming process at the 3-position of the pyrazinone core allowing to attain 3-substituted pyrazinones in good to high yields. 3-Alkylation of 3,5-dichloro-2(1H)-pyrazinones with acetoacetic ester was accompanied by further retro-Claisen fragmentation.
    描述了有效的碱促进的3,5-二氯-2(1 H)-吡嗪酮与各种丙二酸酯的3-烷基化。该方法构成了吡嗪酮核心3位上C–C键形成过程的简单示例,可实现以高产率或高产率获得3-取代的吡嗪酮。3,5-二氯-2(1 H)-吡嗪酮与乙酰乙酸酯的3-烷基化反应伴随着进一步的克莱森反裂解。
  • Straightforward Functionalization of 3,5-Dichloro-2-pyrazinones under Simultaneous Microwave and Ultrasound Irradiation
    作者:Giancarlo Cravotto、Davide Garella、Silvia Tagliapietra、Vaibhav Mehta、Erik Van der Eycken

    日期:2010.1
    Heck reactions and Suzuki-Miyaura cross-couplings with relatively poorly reactive 3,5-dichloro-2-pyrazinones were studied at the same temperature under conventional heating, dielectric heating (MW) and simultaneous MW/US irradiation. This comparative study showed a synergic effect of combined MW and US irradiation resulting in a much higher reaction yield, at the same time avoiding side reactions and partial degradation that is otherwise observed under conventional heating.
    在传统加热、介电加热(MW)和 MW/US 同时辐照的相同温度下,研究了反应性相对较差的 3,5-二氯-2-吡嗪酮的赫克(Heck)反应和苏木-米亚乌拉(Suzuki-Miyaura)交叉耦合反应。这项对比研究表明,MW 和 US 联合辐照可产生协同效应,从而大大提高反应产率,同时避免了在传统加热条件下出现的副反应和部分降解。

    and efficient iodine-mediated intramolecular heteroannulation approach for the construction of the imidazo[1,2-a]pyrazinone core has been developed. Under ambient conditions, this metal-free protocol allows easy access to densely functionalized imidazo[1,2-a]pyrazinone-3-carbaldehydes or (aminomethyl)imidazo[1,2-a]pyrazinones from substrates containing terminal alkynes by cyclization and subsequent
