hitherto unreported aminomethylation occurs at C-3 of imidazopyridines with morpholine in the presence of (diacetoxyiodo)benzene at ambient temperature in short reaction times. This methodology is also applicable to indolizine, imidazo[2,1-b]thiazole, benzo[d]imidazo[2,1-b]thiazole, and indole. Interestingly, the aminomethylation involving morpholine as a source of methylene group is a new phenomenon. This
在(二乙酰氧基碘)苯的存在下,在环境温度下以短的反应时间,在吗啉对咪唑并吡啶的C-3处发生了迄今未报道的氨基甲基化。该方法也适用于吲哚嗪,咪唑并[2,1- b ]噻唑,苯并[ d ]咪唑并[2,1- b ]噻唑和吲哚。有趣的是,涉及吗啉作为亚甲基来源的氨基甲基化是一种新现象。该方案对于在温和的反应条件下合成氨基甲基化衍生物具有很大的潜力。
