  用溴丙二酸二乙酯对噻吩/呋喃进行 C3-乙氧羰基甲基化的简单方法

  摘要：

  以2-取代噻吩/呋喃和溴丙二酸二乙酯为起始原料，开发了一种温和高效的可见光诱导自由基方法制备C3-丙二酸五元杂环化合物。各种2-取代的(苯并)噻吩/呋喃适用于C3-乙氧基羰基甲基化。根据对照实验、循环伏安实验和发光猝灭实验的结果，提出了自由基机理。我们认为杂配卤素桥接的铱（III）二聚体可能在该系统中发挥重要作用。

  羧酸作为铑（III）催化的脱羧C ？的无痕导向基团 噻吩的芳基化

  摘要：

  已开发出铑（III）催化的羧酸与羧酸与噻吩的直接脱羧CH / CH交叉偶联。在基于底物的性质对反应条件进行轻微调整的情况下，具有多种取代基的芳基羧酸可以用作合适的偶联伴侣，并且可以耐受多种官能团。该方法提供了直接使用具有不同取代模式的联芳基支架的方法，其中许多取代模式通常是通过冗长的合成序列进行合成的。一个说明性的例子是通过目前的方法一步法克级合成具有生物活性的3,5-取代的2-芳基噻吩。

  日期：2012.2

  The reaction of thiophene derivatives with Grignard reagent (EtMgCl) and a catalytic amount of amine (Cy2NH) induced the metalation at the α-position. Following addition of several aryl halides in the presence of a nickel or palladium catalyst afforded C–H arylated products in good to excellent yields. The method was successfully applied to facile synthesis of differently-substituted 2,5-diarylthiophenes

  噻吩衍生物与格氏试剂（EtMgCl）和催化量的胺（Cy 2 NH）的反应诱导了α位的金属化。在镍或钯催化剂存在下添加几种芳基卤化物后，可以很好地获得优异收率的CHH芳基化产物。该方法已成功应用于不同取代的2,5-二芳基噻吩的简便合成。

  A series of terarylenes incorporating benzothiophene (BT)/benzofuran (BF) as the central ethene unit was synthesised by using sequential Pd‐catalysed CH activation reactions. This new methodology allows the easy modification of the nature of the pendant heteroarene groups. Diaryl ethene (DAE) derivatives with thiophene, thiazole, pyrrole, isoxazole and pyrazole rings were prepared. A large number
