  摘要：

  由于容易发生不希望的副反应，通过过渡金属催化的无保护基起始原料的偶合反应获得2,2'-二氨基联芳基衍生物的策略的开发是一项具有挑战性的任务。已经描述了利用Ni催化的未保护的2-卤代苯胺类似物的直接均偶联以产生具有容易获得且廉价的联吡啶配体的2,2'-二氨基联芳基。该方法具有高度的化学选择性，广泛的底物范围和官能团相容性，从而突显了该方法。机理和计算研究表明，Ni（0），Ni（I），Ni（II）和Ni（III）物种可能参与催化循环。

  N1修饰的咪唑并喹啉激动剂的设计与合成，以选择性激活Toll样受体7和8

  摘要：

  合成了一系列N1修饰的咪唑并喹啉，并筛选了Toll样受体（TLR）7和8的活性，以识别赋予高亲和力结合和选择性的识别元件。这些受体是免疫调节剂开发中的关键靶标，这些信号指示NF-κB介导的促炎性趋化因子和细胞因子的转录。结果表明，TLR7 / 8活化与N1-取代高度相关，TLR8选择性是通过在该位置包含乙基，丙基或丁基氨基来实现的。虽然结构-活性关系分析表明TLR7活性对N1-修饰不那么敏感，但氨基烷基链长度扩展到戊基和p-甲基苄基引起高亲和力的TLR7结合。还报道了细胞因子谱，表明纯的TLR8激动剂[4-氨基-2-丁基-1-（2-氨基乙基）-7-甲氧基羰基-1 H-咪唑[4,5- c ]喹啉]诱导更高水平的IL与TLR7选择性或混合TLR7 / 8激动剂相比，-1β，IL-12和IFNγ。该结果与先前的研究结果一致，表明TLR8激动剂具有Th1极化作用，可能有助于促进细胞介导的免疫力。

• Synthesis of [3.4]‐Spirooxindoles through Cascade Carbopalladation of Skipped Dienes
  作者：Hamid Azizollahi、Marta Pérez‐Gómez、Vaibhav P. Mehta、José‐Antonio García‐López

  DOI：10.1002/adsc.202000111

  日期：2020.4.27

  route to [3.4]‐spirooxindoles based on cascade carbopalladation reactions of 1,4‐dienes is described. While carbopalladation of alkenes have been used to access mainly [4.4]‐ or [4.5]‐spirocycles, 4‐exo‐trig carbopalladation has not been yet applied to the synthesis of relevant [3.4]‐spirooxindole scaffolds bearing a cyclobutyl ring. In addition, the cascade reaction generates an exocyclic double bond

  描述了基于1,4-二烯级联碳car反应的合成[3.4]-螺毒素的合成途径。虽然烯烃的碳链共轭主要用于获得[4.4]-或[4.5]-螺环，但4- exo - trig碳链共轭尚未用于合成带有环丁基环的[3.4]-螺氧并恶唑骨架。另外，级联反应产生环外双键，该环外双键可以用作进一步使螺氧并吲哚核的取代方式多样化的平台。

  We report herein a two‐step one‐pot strategy for the synthesis of benzoxazoles from amides by using cesium fluoride/copper as catalysts. This approach involves the in situ generation of acyl fluorides from the corresponding amides, and the acyl fluorides undergo transamidation and cyclization to give benzoxazoles in good yields. In this work, the amide C−N bonds are activated by CsF to form the acyl

  我们在此报告一种通过使用氟化铯/铜作为催化剂由酰胺合成苯并恶唑的两步一锅策略。该方法涉及从相应的酰胺中原位生成酰基氟，并且该酰基氟经过转酰胺基化和环化以良好的收率得到苯并恶唑。在这项工作中，酰胺C-N键被CsF活化形成酰基氟中间体，该中间体进一步与邻溴代苯胺反应以有效生成苯并恶唑。值得注意的是，该方法论证了广泛的底物范围，因为伯/仲苯甲酰胺具有很好的耐受性，并且该过程可能有助于酰胺一锅转化的发展。
