  studies on anti-helicobacter pylori agents. part 2: new cephem derivatives

  摘要：

  The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of cephem derivatives are described. Introduction of thio-heterocyclic groups containing N- and S-atoms to the 3-position and phenyl or thienyl acetamido groups to the 7-position of the cephem nucleus dramatically improved the activity. From this series of derivatives, compound 13i was Found to have extremely potent in vitro anti-H. pylori activity, superior therapeutic efficacy compared to AMPC and CAM, no cross-resistance between CAM or MNZ and low potential for causing diarrhea due to instability to beta-lactamase.

  一种通过二氮杂苯吡唑-3-酮的简单方法

  摘要：

  描述了从首先被转化成相应的酰肼的丙烯酸开始有效地进入吡唑-3-酮。酰肼的氧化产生了二氮烯，并且在用ZrCl 4处理时将其环化成吡唑-3-酮。在温和的反应条件下，容易除去吡唑啉酮衍生物的N-1的甲氧基羰基保护基。

• A simple approach to pyrazol-3-ones via diazenes

  An efficient entry into pyrazol-3-ones is described starting from propenoic acids that were first transformed into the corresponding hydrazides. Oxidation of the hydrazides gave the diazenes and the latter cyclized to pyrazol-3-ones on treatment with ZrCl4. The methoxycarbonyl protection of the N-1 of the pyrazolone derivatives was easily removed under mild reaction conditions.

  general strategy for the intermolecular synthesis of polysubstituted cyclopentenones using palladium catalysis. Overall, this reaction is achieved via a molecular shuffling process involving an alkyne, an α,β-unsaturated acid chloride, which serves as both the alkene and carbon monoxide source, and a hydrosilane to create three new C-C bonds. This new carbon monoxide-free pathway delivers the products

  我们描述了使用钯催化分子间合成多取代环戊烯酮的一般策略。总体而言，该反应是通过涉及炔烃、α,β-不饱和酰氯（作为烯烃和一氧化碳来源）和氢硅烷的分子改组过程实现的，以产生三个新的 CC 键。这种新的无一氧化碳途径提供了具有优异产量的产品。此外，区域选择性是对环戊烯酮合成常规方法的补充。此外，还提出了一组区域和化学发散反应，以强调这种新策略的合成潜力。

  在这里，我们报告说，容易获得的基于甲硅烷基和硼的路易斯酸与手性铜催化剂结合能够克服未活化的烯酰胺（被称为反应性最低的羧酸衍生物）对有机镁试剂进行烷基化的反应性问题。在催化不对称共轭加成到烯酰胺中允许无与伦比的化学反应性和立体控制，该方法以其前所未有的反应范围而著称，即使是最具挑战性和合成上重要的甲基化也能以良好的产率和出色的对映选择性完成。该催化协议可耐受较宽的温度范围（-78 °C 至环境温度）和放大（10 g），而手性催化剂可以重复使用而不会影响整体效率。
