We have developed an efficient copper‐catalyzed method for the synthesis of N‐alkylanthranilic acids. The protocol uses inexpensive copper(I) iodide/racemic 1,1′‐binaphthyl‐2,2′‐diol (rac‐BINOL) as the catalyst/ligand system, readily available 2‐halobenzoic acids and aliphatic amines as the starting materials, the coupling reactions were performed at room temperature, and various functionalities in
我们已经开发出一种有效的铜催化方法来合成N-烷基邻氨基苯甲酸。该协议使用廉价的碘化铜(I)/外消旋1,1'-联萘-2-2,2'-二醇(rac ‐BINOL)作为催化剂/配体体系,现成的2-卤代苯甲酸和脂肪族胺作为起始原料,偶联反应在室温下进行,并且可以耐受底物中的各种功能。
