  Palladium-Catalyzed Alcoholysis of 3-Iodopropynamides: Selective Synthesis of Carbamoylacetates

  摘要：

  A novel and selective method for the synthesis of carbamoylacetates via the alcoholysis of 3-iodopropynamides has been developed. 3-Iodopropynamides react with alcohols in the presence of palladium(II) acetate and DABCO to afford the corresponding carbamoylacetates in moderate to good yields.

  iodoethynes with arylboronic acids under aerobic conditions has been developed. In the presence of palladium(II) acetate and cesium carbonate, a variety of iodoethynes underwent the Suzuki­-Miyaura cross-coupling reaction with arylboronic acids at room temperature to afford the corresponding internal alkynes in moderate to good yields. It is noteworthy that this protocol proceeds under mild and aerobic conditions

  在有氧条件下，开发了无配体钯催化的碘乙炔与芳基硼酸的铃木-宫浦交叉偶联。在乙酸钯（II）和碳酸铯的存在下，各种碘乙炔在室温下与芳基硼酸进行了Suzuki-Miyaura交叉偶联反应，以中等至良好的收率提供了相应的内部炔烃。值得注意的是，该方案在温和有氧条件下进行而无需配体的帮助。 钯-碘乙炔-芳基硼酸-铃木宫浦-交叉偶联-炔烃
