A green and efficient one-pot method has been developed for the synthesis of 2-pyridone and functionalized azaxanthone frameworks using indium triflate as an environmentally friendly, reusable catalyst. In this one-pot reaction, 3-formylchromones display a diverse pattern of reactivity upon reaction with different classes of alkenes. An indium triflate-promoted reaction with (Z)-N-methyl-1-(methyl
已经开发了一种绿色高效的一锅法,该方法使用三氟甲磺酸铟作为环境友好的可重复使用的催化剂来合成2-吡啶酮和功能化的氮杂蒽酮骨架。在这种一锅法反应中,3-甲酰基色酮与不同种类的烯烃反应后显示出多种反应模式。与(Z)-N-甲基-1-(甲硫基)-2-硝基乙胺的三氟甲磺酸铟促进的反应通过显着方便的色酮开环将3-甲酰基色酮环化为2-吡啶酮和类似物。与N,N'-二甲基-2-硝基乙烯-1,1-二胺的类似反应导致通过合成形成有用的功能化氮杂黄嘌呤 6π-电环化反应。
