The synthesis of hitherto unreported 5-amino-7-alkoxy2-methyl-2,4-aryl-1,2-dihydro-1,6-naphthyridine-8-carbonitriles (4) was accomplished by a one-pot pseudo five-component reaction using aryl methyl ketones or alkyl methyl ketones, malononitrile, and alcohols in the presence of sodium hydroxide under reflux conditions. By following an identical reaction procedure, various 5-amino-2-methyl-2,4
迄今为止未报道的 5-amino-7-alkoxy2-methyl-2,4-aryl-1,2-dihydro-1,6-naphthyridine-8-carbonitriles (4) 的合成是由一锅伪五组分完成的在回流条件下,在氢氧化钠存在下使用芳基甲基酮或烷基甲基酮、丙二腈和醇进行反应。通过遵循相同的反应程序,各种 5-amino-2-methyl-2,4
