  阻转异构联芳基的催化对映选择性合成：阳离子定向的亲核芳香取代反应。

  摘要：

  已经开发出催化对映体选择性亲核芳族取代反应，该反应以优异的收率和高达97：3的er值产生轴向手性联芳基衍生物。该方法使用手性抗衡离子通过串联不对称化/动力学拆分机制将硫酚盐添加到前手性二氯嘧啶上。该产物可以衍生为一系列的阻转异构体结构，而对映体富集度没有任何降低，因此提供了未开发的手性联芳基结构的途径。

  The present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide or amine moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In additional embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between a nitrogen atom of an acyl hydrazine and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of a nitrogen-containing heteroaromatic, e.g., indole, pyrazole, and indazole, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-oxygen bond between the oxygen atom of an alcohol and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. The present invention also relates to copper-catalyzed methods of forming a carbon-carbon bond between a reactant comprising a nucleophilic carbon atom, e.g., an enolate or malonate anion, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. Importantly, all the methods of the present invention are relatively inexpensive to practice due to the low cost of the copper comprised by the catalysts.

  本发明涉及铜催化的碳-杂原子和碳-碳键形成方法。在某些实施例中，本发明涉及铜催化的方法，用于在酰胺或胺基团的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在其他实施例中，本发明涉及铜催化的方法，用于在酰基肼的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在另一些实施例中，本发明涉及铜催化的方法，用于在含氮杂环芳烃（例如吲哚、吡唑和吲哌）的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在某些实施例中，本发明涉及铜催化的方法，用于在醇的氧原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氧键。本发明还涉及铜催化的方法，用于在包含亲核碳原子的反应物（例如烯醇酸盐或丙二酸盐负离子）与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-碳键。重要的是，由于催化剂中铜的低成本，本发明的所有方法都相对廉价。

• A General and Mild Copper-Catalyzed Arylation of Diethyl Malonate
  作者：Edward J. Hennessy、Stephen L. Buchwald

  DOI：10.1021/ol017038g

  日期：2002.1.1

  GRAPHICSA general method for the synthesis of alpha-aryl malonates is described. The coupling of an aryl iodide and diethyl malonate in the presence of Cs2CO3 and catalytic amounts of copper(I) iodide and 2-phenylphenol affords the alpha-aryl malonate in good to excellent yields. The mild reaction conditions and high levels of functional group compatibility make this an attractive synthetic alternative to previous methods.
