  CuI/N,N-Dimethylglycine-Catalyzed Coupling of Vinyl Halides with Amides or Carbamates

  摘要：

  The Cul-catalyzed coupling reaction of vinyl halides with amides or carbamates proceeds well at room temperature to 80 degreesC in dioxane to give enamides using NN-dimethylglycine as the promoter and Cs2CO3 as the base. The geometry of the C-C double bond is retained during the reaction course.

  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。
• Regioselective Hydrothiolation of Alkenes Bearing Heteroatoms with Thiols Catalyzed by Palladium Diacetate

  日期：2014.6.6

  examples of transition-metal-catalyzed hydrothiolation of alkynes, the corresponding catalytic addition of thiols to alkenes has remained undeveloped. However, a novel Pd-catalyzed addition of thiols to alkenes bearing a heteroatom, such as oxygen and nitrogen, is found to proceed under mild conditions to give the corresponding Markovnikov adducts, regioselectively, in good yields.

  与过渡金属催化的炔烃氢硫醇化反应的许多实例形成鲜明对比的是，尚未开发出相应的硫醇向烯烃的催化加成反应。然而，发现在温和的条件下，新型的钯催化的硫醇向带有杂原子的烯烃（如氧和氮）进行新型的Pd催化加成反应，可以区域选择性地以高收率得到相应的马尔可夫尼科夫加合物。
