  Identification and structure-based optimization of novel dihydropyrones as potent HCV RNA polymerase inhibitors

  摘要：

  A novel class of non-nucleoside HCV NS5B polymerase inhibitors has been identified from screening. A co-crystal structure revealed an allosteric binding site in the protein that required a unique conformational change to accommodate inhibitor binding. Herein we report the structure-activity relationships (SARs) of this novel class of dihydropyrone-containing compounds that show potent inhibitory activities against the HCV RNA polymerase in biochemical assays.

  摘要：

  由苯胺在液体SO 2中的溴化速率常数确定的十一种取代衍生物的反应结构相关性，与在水中观察到的不同，表明该反应对取代基效应高度敏感（ρ= −7.1；ρ= −10.51）。该结果归因于甲氧基的溶剂化，与邻位取代的衍生物（ρ= -8.86）相比，其降低了对位取代的共轭（ρ= -9.70 ）。高度溶剂化的过渡态在反应坐标上与反应物相距甚远，在此状态下产生的正电荷几乎为1。

  reductive coupling for the synthesis of benzonitriles from aryl (pseudo)halides and an electrophilic cyanating reagent, 2-methyl-2-phenyl malononitrile (MPMN). MPMN is a bench-stable, carbon-bound electrophilic CN reagent that does not release cyanide under the reaction conditions. A variety of medicinally relevant benzonitriles can be made in good yields. Addition of NaBr to the reaction mixture allows for

  在此，我们报告了一种 Ni 催化的还原偶联，用于从芳基（伪）卤化物和亲电氰化试剂 2-甲基-2-苯基丙二腈 (MPMN) 合成苯甲腈。MPMN 是一种工作台稳定的碳键合亲电子 CN 试剂，在反应条件下不会释放氰化物。可以以良好的收率制备多种与药用相关的苯甲腈。将 NaBr 添加到反应混合物中可以使用更具挑战性的芳基亲电试剂，例如芳基氯化物、甲苯磺酸盐和三氟甲磺酸盐。机理研究表明，溴化钠在促进这些底物的氧化加成方面发挥作用。

  Although iodine-catalyzed reaction has rapid advances in recent years, examples on iodine-catalyzed bromination are rare and the mechanism of these reactions remains unclear. Herein, we reported an I2-catalyzed aromatic bromination of aryl ethers by NBS and presented the details of the mechanistic study including kinetic study and the study of kinetic isotope effects. The study revealed that the reaction
