N,N′-(Phenylmethylene)diacetamide analogues which were simply prepared from the condensation reaction of an aldehyde with an amide or urea were found to be efficient ligands in copper-catalyzed coupling reaction of aryl halides with various azole nucleophiles. The newly developed ligand showed broad application scope in this conversion. Compounds including imidazoles, benzoimidazoles, pyrrole, indole, and benzotriazole were successfully arylated with diversified aromatic halides to give corresponding products in moderate to excellent yields.
N,N′-(苯亚甲基)二乙酰胺类似物是通过醛与酰胺或尿素的缩合反应简单制备而成的,发现其在铜催化的芳基卤化物与各种杂环核苷酸的偶联反应中是有效的配体。新开发的配体在该转化过程中显示了广泛的应用范围。包括咪唑、苯并咪唑、呋喃、吲哚和苯并三唑等化合物成功地与多样化的芳香卤化物发生芳基化反应,得到相应的产物,产率中等到优秀。
