α-substituted 2-bromo-β-methoxystyrene derivatives and n-butyllithium generates α-substituted 2-lithio-β-methoxystyrene derivatives, which successfully react with a range of nitriles to afford the corresponding 1,4-disubstituted isoquinolines in reasonable yields.
已经发现α-取代的2-溴-β-甲氧基苯乙烯衍生物和正丁基锂之间的卤素-锂交换生成α-取代的2-锂-β-甲氧基苯乙烯衍生物,其成功地与一系列腈反应得到相应的1,4-二取代异喹啉的收率合理。
