Copper-catalyzed amination of aryl bromides and iodides under mild conditions has been developed with 2-dimethylaminoethanol as ligand and water as solvent. A variety of hydrophilic and hydrophobic aryl halide substrates have been aminated in good yield with a variety of amino acids, amino alcohols and peptides. This method has successfully N-arylated some hydrophilic amino compounds not available
以2-二甲基氨基乙醇为配体,水为溶剂,在温和条件下进行了铜催化的芳基溴化物和碘化物的胺化反应。各种亲水性和疏水性芳基卤化物底物均已与各种氨基酸,氨基醇和肽以高收率胺化。该方法已成功地使一些其他方法无法获得的亲水性氨基化合物N-芳基化。
