protocol for the synthesis of 2-arylquinolines via tandem reaction of 2-aminostyryl nitriles with arylboronic acids has been developed with good functional group tolerance. The presented approach offers a new synthetic pathway toward the core structures of 2-arylquinolines compared to classical condensation reaction of (E)-2-aminostyryl aryl ketones. Moreover, the present synthetic route could be readily
通过2-氨基苯乙烯基腈与芳基硼酸的串联反应合成2-芳基喹啉的新型钯催化方案已被开发出来,具有良好的官能团耐受性。与(E)-2-氨基苯乙烯基芳基酮的经典缩合反应相比,本方法为2-芳基喹啉的核心结构提供了一条新的合成途径。而且,本合成路线可以容易地按比例放大至克量而没有困难。初步的机械实验表明,这种转化涉及芳基钯物质向腈的亲核加成,以生成芳基酮中间体,然后进行分子内环化和脱水成喹啉环。
