中文摘要：
以I2／KI为氧化剂，甲苯为乳化剂，对硝基苯胺（2）和巴豆醛（3）经环合反应合成了6-硝基喹哪啶（1）。最佳反应条件为：28．92mmol，甲苯10mL，混酸45．5mL[V（AcOH）：V（HCl）=1：90]，n（2）：n（12／KI）=1：1，于100℃反应4h，收率达93．1％。1的结构经1^H NMR，IR和元素分析表征。
英文摘要：
6-Nitrylquinaldine（ 1 ） was synthesized by cyclization of p-nitroaniline（2） with crotonalde- hyde（3） using I2/KI as the oxidant and toluene as the emulsifier. The structure was characterized by 1^ H NMR, IR and elemental analysis. The optimum reaction conditions at 100 ℃ for 4 h were as follows： 2 was 8.92 mmol; toluene was 10 mL; mixed acid[ V（AcOH） ： V（HCl） = 1：90] was 45.5 mL; n（2） ： n（I2/KI） = 1 ： 1. The yield of 1 can reach 93.1% under the conditions.
