The nonmetal catalytic oxidation system I2/tert-butyl hydroperoxide (TBHP) has been unprecedentedly applied to a three-component domino reaction and simultaneously a simple and efficient protocol has been developed to newly synthesize 2-aryl-N-substitutied quinazoline-4-amines in one pot from isatoic anhydride, aromatic amine, and another amine containing methylene adjacent to nitrogen. This protocol
非金属催化氧化系统 I2/叔丁基过氧化氢 (TBHP) 已前所未有地应用于三组分多米诺骨牌反应,同时开发了一种简单有效的方案来新合成 2-芳基-N-取代的喹唑啉-4-胺在一个锅中,由靛红酸酐、芳香胺和另一种含有与氮相邻的亚甲基的胺组成。该协议是新的和实用的,因为在胺 2 或 3 上取代的给电子和吸电子基团都可以存活并以合理的产率提供相应的产品。与逐步程序不同,碘对于三组分一锅反应至关重要。
