A shorter, alternative synthesis of 8-amino-2-methyl-3,4-dihydroisoquinolin-1-one is described in 32% overall yield, over three steps starting from commercially available 2-methyl-6-nitrobenzonitrile. The synthesis includes two ‘one-pot’ procedures in which the key process involves the microwave-assisted hydrolysis of a nitrile group followed by lactamization under elevated temperatures.
本研究介绍了一种 8-氨基-2-甲基-3,4-二氢异喹啉-1-酮的简短替代合成方法,该方法以市售的 2-甲基-6-硝基苯甲腈为原料,通过三个步骤合成,总收率为 32%。该合成包括两个 "一锅 "过程,其中的关键步骤是微波辅助水解腈基,然后在高温下进行内酰胺化。
