    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.

  • Intramolecular Diels-Alder reactions of 2(1H)-pyrazinones: Synthesis of new Furo/Pyrano-pyridinones and -pyridines
    作者:Kris J. Buysens、Didier M. Vandenberghe、Suzanne M. Toppet、Georges J. Hoornaert

    4-alkynyloxy side chain and 2(1H)-pyrazinones 9–10 carrying the corresponding 2- or 3-alkynyloxy(m)ethyl substituent are shown to undergo intramolecular Diels-Alder reaction. The formation of either fused pyridinones 13, 16, 20, 22 or 24 and/or pyridines 14, 17, 19 or 25 depends on the substitution pattern of the anchored pyrazinone and runs via the loss of either nitrile or isocyanate from the intermediate

    Furthermore, following hydrogenolysis of the 5-chloro substituent and regioselective 5-bromination, this palladium-catalysed cross-coupling approach could be extended to the synthesis of the analogous 5-substituted 2(1H)-pyrazinones.

  • A straightforward microwave method for rapid synthesis of N-1, C-6 functionalized 3,5-dichloro-2(1H)-pyrazinones

    A rapid and versatile one-pot, 2 × 10 min microwave protocol for the preparation of N-1 and C-6 decorated 3,5-dichloro-2(1H)-pyrazinones was developed. Comparable reaction sequences using classical conditions require about 1–2 days of heating. The α-aminonitrile was first generated in a Strecker reaction and thereafter cyclized under microwave heating. The microwave approach developed offers the possibility of efficiently generating and utilizing functionalized 3-amino-5-chloro-2(1H)-pyrazinone-N-1-carboxylic acids as β-strand inducing core structures in a medicinal chemistry context. To illustrate the usefulness of the method, the synthesis of two novel 2(1H)-pyrazinone-containing Hepatitis C virus NS3 protease inhibitors is reported.
    开发了一种快速且多功能的单锅法2×10分钟微波协议,用于制备N-1和C-6修饰的3,5-二氯-2(1H)-吡嗪酮。使用经典条件进行的可比反应序列需要大约1-2天的加热时间。首先通过斯特雷克反应生成α-氨基腈,然后在微波加热下环化。所开发的微波方法提供了高效生成和利用功能化的3-氨基-5-氯-2(1H)-吡嗪酮-N-1-羧酸作为药物化学背景下β-链诱导核心结构的可能性。为了说明该方法的实用性,报道了两个新型含有2(1H)-吡嗪酮的丙型肝炎病毒NS3蛋白酶抑制剂的合成。

    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.
