3-(P-Chlorobenzylidene)-5, 7-dimethyl-2, 3-dihydro-1H-cyclopenta[b]quinoline-9-(di-n-butylaminomethyl)methanol and 2-[beta-(p-chlorostyryl)]-6, 8-dimethylquinoline-4-(di-n-butylaminomethyl)methanol were synthesized from 6, -8-dimethyl-4-hydroxycarbostyril by 3, 3-dichlorination, dimethoxylation th the 3-ketal, basic hydrolysis to the glyoxal acetal, Pfitzinger condensation with cylopentanone or acetone
3-(对氯亚苄基)-5、7-二甲基-2、3-二氢-1H-环戊[b]喹啉-9-(二正丁基氨基甲基)甲醇和2-β-(对氯苯乙烯基)]由6,-8-二甲基-4-羟基卡斯蒂尔通过3,3-二氯化,3-甲氧基二甲氧基化,3-酮基的二甲氧基化反应合成了-6,8-二甲基喹啉-4-(二-正丁基氨基甲基)甲醇。 ,Pfitzinger与环戊烷酮或丙酮缩合为2,3-三亚甲基或2-甲基喹啉,与p-ClPhCHO在2-亚甲基或2-甲基缩合,水解为4-喹醛,亚甲基化为环氧化物,并与Bu2NH。两者均对小鼠伯氏疟原虫具有治愈作用。第一种是更有效的:在10 mg / kg时有活性,在40 mg / kg时完全治愈,对动物只有轻度的光毒性。
