  优化芳霉素抗生素活性的初步努力

  摘要：

  虽然大多数临床使用的抗生素来自天然产物，但新的广谱天然产物的分离变得越来越罕见，而且由于其支架或靶标的内在限制，通常认为窄谱药物不适合开发。然而，天然产物抗生素的谱可能会受到某些细菌特定耐药机制的限制，例如靶点突变，并且这种“潜在”抗生素的谱可能会通过衍生化重新优化，就像之前所做的那样临床部署的抗生素。我们最近展示了 arylomycin 天然产物抗生素的谱系，它们通过抑制 I 型信号肽酶的新机制起作用，比以前认为的更广泛，并且几种关键人类病原体的耐药性是由于目标肽酶中存在特定的 Pro 残基，该残基破坏了与抗生素脂肽尾部的相互作用。为了开始测试这种天然抗性是否可以通过衍生化来克服，我们合成了脂肽尾部改变的类似物，并确定了几种具有增加的抗金黄色葡萄球菌。数据支持了芳霉素是潜在抗生素的假设，表明它们的谱可以通过衍生化进行优化，并确定了未来优化工作可能会关注的有前途的支架。

• Generation and Cross-Coupling of Organozinc Reagents in Flow
  作者：Ananda Herath、Valentina Molteni、Shifeng Pan、Jon Loren

  日期：2018.12.7

  formation of organozinc reagents and subsequent cross-coupling with aryl halides and activated carboxylic acids is reported. Formation of organozinc reagents is achieved by pumping organic halides, in the presence of ZnCl2 and LiCl, through an activated Mg-packed column under flow conditions. This method provides efficient in situ formation of aryl, primary, secondary, and tertiary alkyl organozinc reagents

  报道了一种通用的流动合成方法，用于原位形成有机锌试剂，然后与芳基卤化物和活化的羧酸进行交叉偶联。有机锌试剂的形成是通过在流动条件下将有机卤化物在ZnCl 2和LiCl的存在下泵送通过活化的Mg填充柱来实现的。该方法可有效地原位形成芳基，伯，仲和叔烷基有机锌试剂，随后将其在下游进行Negishi或脱羧Negishi交叉偶联反应的伸缩。所描述的方法提供了使用有机锌试剂获得各种C–C键的方法，这些试剂否则在商业上是不可用的，或者在传统的间歇反应条件下难以制备。

  for the preparation of homologated derivatives suitable for amination in the presence of silver (I) trifluoroacetate to afford the corresponding β-ketoamides is discussed. In particular Wadsworth-Emmons coupling reactions of (2) with various carbonyl compounds gave good yields of E-substituted products. Many of the β-ketoamides were shown to be suitable precursors for 3-acyltetramic acids using a Dieckmann

  3-氧代丁氧硫醇叔丁酯（1）和4-二乙基氧代-3-氧杂丁硫醇叔丁酯（2）的制备适合于在三氟乙酸银（I）存在下进行胺化的同系化衍生物，得到相应的β讨论了β-酮酰胺。特别地，（2）与各种羰基化合物的Wadsworth-Emmons偶联反应给出了良好的E-取代产物收率。使用Dieckmann环化反应，以四正丁基氟化铵为环化碱，发现许多β-酮酰胺是3-酰基四酸的合适前体。这些新的反应应用于多烯3-酰基四酸富叶红素A的全合成。
