Syntheses of 9-acridine- and 2-phenanthridinemethanols as potential antimalarials
摘要:
alpha-(1-Piperidinylmethyl)-9-acridinemethanol (3), alpha-[(dibutylamino)ethyl]-9-acridanmethanol (4a), and alpha-[(dibutylamino)methyl]-2-phenanthridinemethanol (5) have been made and all are ineffective as antimalarials against Plasmodium berghei in mice. 9-Acridinyloxirane showed no significant mutagenicity for strains TA 98 or TA 100 of Salmonella typhimurium.

Treatment of quinolines bearing methyl, fluoro, chloro, bromo, acetyl, methoxycarbonyl, trifluoromethyl, or cyano groups with Na2S2O8 in a mixture of methanol and water at 70 °C for 4 h gave the corresponding hydroxymethylated compounds in good to moderate yields. The hydroxymethyl group of the product was transformed into aldehyde, ester, amide, aminomethyl, cyano, and tetrazole groups.
在甲醇和水的混合物中,用Na 2 S 2 O 8在70°C下处理带有甲基,氟,氯,溴,乙酰基,甲氧基羰基,三氟甲基或氰基的喹啉4小时,得到相应的羟甲基化化合物中等产量。产物的羟甲基被转化为醛,酯,酰胺,氨甲基,氰基和四唑基。
Visible light-induced hydroxymethylation and formylation of (iso)quinolines with alcohols
Herein, a mild and effective hydroxymethylation and formylation of quinolines or isoquinolines with methanol in the absence of external acids and transition metals is described using the coupling reaction promoted by PhIFA and visible light. A variety of substituted quinolines or isoquinolines proceed the reaction smoothly, providing the corresponding products in moderate-to-good yields. Control experiments
