A facile and elegant syntheses of linear and angular phenyl‐substituted dibenzonaphthyridines from 2,4‐dichloroquinolines through anilinoquinolines have been developed. The substituents in the 4th position of the anilinoquinoline and the temperature were found to play a vital role in the regulation of the yield towards the synthesis of the final compounds. The methyl group in the 7th position of the
已经开发了一种简便而优美的方法,可从2,4-二氯喹啉到苯胺喹啉合成线性和角苯基取代的二苯并萘啶。发现在苯胺喹啉的第4位上的取代基和温度在最终化合物合成的产率调节中起着至关重要的作用。发现萘啶11-11位的7位上的甲基在空间上阻碍N-甲基化反应,因此比其他衍生物增加了反应时间。
