3-[4-(2-bromoacetyl)phenyl]-1-methylquinolin-2(1H)-one. The latter reacted with pyridine, 4-methylpyridine, quinoline, benzo[f]quinoline, and triphenylphosphine to afford the corresponding quaternary salts, and its reactions with thioacetamide, thiourea, 2-aminopyridine, and 2-aminopyrimidine led to the corresponding thiazole, imidazo[1,2-a]pyridine, and imidazo[1,2-a]pyrimidine derivatives containing a 2-oxoquinoline
1-甲基喹啉-2(1 H)-one与4-乙酰基苯重氮的Meerwein反应得到3-(4-乙酰苯基)-1-甲基喹啉-2(1 H)-溴化为3- [4-( 2-溴乙酰基)苯基] -1-甲基喹啉-2(1 H)-一。后者与吡啶,4-甲基吡啶,喹啉,苯并[ f ]喹啉和三苯基膦反应,得到相应的季盐,其与硫代乙酰胺,硫脲,2-氨基吡啶和2-氨基嘧啶的反应生成相应的噻唑,咪唑含有2-氧代喹啉片段的[1,2- a ]吡啶和咪唑并[1,2- a ]嘧啶衍生物。3-(4- 2- [2-(芳基亚甲基)肼基] -1,3-噻唑-4-基}苯基)-1-甲基喹啉-2(1ħ) -酮通过3- [4-(2-溴乙酰基)苯基]缩合得到-1-甲基喹啉-2(ħ醛) -酮与氨基硫脲和芳族的。
