A method was developed for the synthesis of 4-alkyl-3,4-dihydronaphtho[2,3-f]quinoxaline-2,7,12-(1H)-triones starting from 1-chloroacetylamino-2-halo-9,10-anthraquinones and primary and secondary amines. The reactions of 1-amino-2-alkylamino-9,10-anthraquinones with chloroacetyl chloride afforded 3-alkyl-5-arylamino-2-chloromethyl-3H-anthra[1,2-d]-imidazole-6,11-diones. The reaction products contain chloroalkyl groups, which can undergo further modifications.
以 1-氯乙酰氨基-2-卤代-9,10-蒽醌和伯胺、仲胺为起始原料,开发了一种合成 4-烷基-3,4-二氢萘并[2,3-f]喹喔啉-2,7,12-(1H)-三酮的方法。1-氨基-2-烷基氨基-9,10-蒽醌与氯乙酰氯反应,可得到 3-烷基-5-芳基氨基-2-氯甲基-3H-蒽并[1,2-d]-咪唑-6,11-二酮。反应产物含有氯烷基,可进行进一步修饰。
