    Discovery of novel piperonyl derivatives as diapophytoene desaturase inhibitors for the treatment of methicillin-, vancomycin- and linezolid-resistant Staphylococcus aureus infections
    摘要:
    Inhibition of S. aureus diapophytoene desaturase (CrtN) could serve as an alternative approach for addressing the tricky antibiotic resistance by blocking the biosynthesis of carotenoid pigment which shields the bacterium from host oxidant killing. In this study, we designed and synthesized 44 derivatives with piperonyl scaffold targeting CrtN and the structure-activity relationships (SARs) were examined extensively to bring out the discovery of 21b with potent efficacy and better hERG safety profile compared to the first class CrtN inhibitor benzocycloalkane derivative 2. Except the excellent pigment inhibitory activity against wild-type S. aureus, 21b also showed excellent pigment inhibition against four pigmented MRSA strains. In addition, H2O2 killing and human whole blood killing assays proved 21b could sensitize S. aureus to be killed under oxidative stress conditions. Notably, the murine study in vivo validated the efficacy of 21b against pigmented S. aureus Newman, vancomycin-intermediate S. aureus Mu50 and linezolid-resistant S. aureus NRS271.

  • Heck Cross-Coupling of Aryldiazonium Tetrafluoroborate with Acrylates Catalyzed by Palladium on Charcoal
    作者:François-Xavier Felpin、Eric Fouquet、Cécile Zakri
    DOI:10.1002/adsc.200800539
    日期:2008.11.3
    relationship study of various palladium supported on charcoal (Pd/C) catalysts has been undertaken for the Heck reaction of aryldiazonium tetrafluoroborate with acrylates. The optimized protocol enables the cross-coupling with a low loading of palladium at room temperature in technical grade methanol. Although the catalyst could not be recycled at this time, measurement of the palladium content by inductively
    对于四氟硼酸芳基重氮鎓与丙烯酸酯的Heck反应,已经进行了各种负载在木炭(Pd / C)催化剂上的钯的性能-活性关系研究。经过优化的方案可以在室温下以工业级甲醇与低负载的钯进行交叉偶联。尽管此时催化剂无法循环使用,但通过电感耦合等离子体质谱法(ICP-MS)对钯含量的测量表明,钯对溶剂和产物的污染较低,与均匀条件相比,该方法对环境更安全。
  • Mizoroki–Heck Reaction of Unstrained Aryl Ketones via Ligand-Promoted C–C Bond Olefination

    Mizoroki–Heck reaction of unstrained aryl ketone with acrylate/styrene is accomplished via palladium-catalyzed ligand-promoted C–C bond cleavage. Various (hetero)aryl ketones are compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived aryl ketones demonstrate the synthetic utility
    未应变的芳基酮与丙烯酸酯/苯乙烯的Mizoroki-Heck反应是通过钯催化的配体促进的C-C键裂解实现的。各种(杂)芳基酮在反应中是相容的,从而以良好至优异的产率提供了烯烃产物。在某些药物,天然产物和香料衍生的芳基酮的后期烯烃聚合中的进一步应用证明了该方案的合成效用。通过采用酮作为导向基团和离去基团二者,1,2- bifunctionalization经由顺序实现邻-C-H的烷基化/本位-Heck烯。
  • Evidences of release and catch mechanism in the Heck reaction catalyzed by palladium immobilized on highly cross-linked-supported imidazolium salts
    作者:Cinzia Pavia、Francesco Giacalone、Lucia Anna Bivona、Anna Maria Pia Salvo、Chiara Petrucci、Giacomo Strappaveccia、Luigi Vaccaro、Carmela Aprile、Michelangelo Gruttadauria
    DOI:10.1016/j.molcata.2014.02.025
    日期:2014.6
    Palladium (10 wt%) on a highly cross-linked imidazolium-based material was used as catalyst in 0.1 mol% in the Heck reaction between several alkenes and aryl iodides. Products were obtained from good to high yields. Deeper investigations showed a release of Pd species in solution and their capture by the imidazolium-based support. When a sixfold amount of support was employed the re-captured Pd species
    在几种烯烃与芳基碘化物之间的Heck反应中,高度交联的咪唑基材料上的钯(10 wt%)以0.1 mol%的比例用作催化剂。从高产率到高产率获得产物。更深入的研究表明,溶液中Pd会释放,并被咪唑基载体捕获。当使用六倍量的载体时,重新捕获的Pd种类(0.5–0.6 wt%)不再具有催化活性。该结果代表了这项工作的一个新的有趣方面,因为高度交联的咪唑基材料还可以用作Pd清除剂,从而避免了溶液中金属的释放。当在清除载体存在下进行反应时,已经证明了Heck反应和Suzuki反应之间的重要差异。
  • Preparation of 2-Quinolones by Sequential Heck Reduction-Cyclization (HRC) Reactions by Using a Multitask Palladium Catalyst
    作者:François-Xavier Felpin、Jérôme Coste、Cécile Zakri、Eric Fouquet
    DOI:10.1002/chem.200900583
    日期:2009.7.20
    One‐pot sequential Heck reduction–cyclization (HRC) reactions leading to the synthesis of substituted 2‐quinolones have been developed by using a heterogeneous or mixed homogeneous/heterogeneous multitask palladium catalyst with charcoal as a support. The whole sequence occurs under very mild conditions without the need for additives (ligand or base) by taking advantage of the high reactivity of aryldiazonium
    通过使用木炭作为载体的异相或混合均相/非均相多任务钯催化剂,已经开发出了导致合成2-喹诺酮的单锅顺序Heck还原-环化(HRC)反应。通过利用芳基重氮盐的高反应活性作为“超级亲电子试剂”,整个序列在非常温和的条件下发生,而无需添加剂(配体或碱)。循环实验表明,重复使用的非均相Pd 0 / C催化剂不能促进另一个HRC序列,但是对于加氢,加氢脱卤以及氢解反应仍然具有很高的活性。

    renewable solvent. The intermediates of the Wittig reaction were analyzed by 31P NMR spectroscopy, and in situ NMR experiments confirmed phosphane oxide as the resting state of the catalyst. Further kinetic investigations revealed a striking influence of the base on the rate of phosphane oxide reduction.
    近来,磷氧化还原循环对于最初要求使用化学计量的磷试剂的许多转化已变得非常重要。尽管这些方法具有多种优势,但催化剂负载量高(≥10 mol%)和苛刻的反应条件(T≥100°C)通常会限制其通用性和适用性。在本文中,我们报道了不同取代的氧化膦作为有效的Wittig反应催化剂。磷脂骨架易于修饰,并且可以通过简单的两步合成获得多种催化剂。Wittig反应中的活性大大超过了先前报道的基于磷杂环戊烷的催化剂,并且即使在室温下,该反应也可以以低至1.0 mol%的催化剂负载量进行。此外,在这些温和条件下不再需要布朗斯台德酸添加剂即可实现高收率。甲基取代的氧化膦用于合成25种不同的烯烃,收率高达97%。该方法具有良好的官能团耐受性,该反应可以从烷基氯化物,溴化物,或碘化物。另外,可以在使用2-MeTHF作为可再生溶剂的催化Wittig反应中使用聚(甲基氢硅氧烷)作为末端还原剂。Wittig反应的中间体通过31
