efficient Fe/Cu relay-catalyzed domino protocol has been developed for the synthesis of 2-phenylquinazolin-4-amines from commercially available ortho-halogenated benzonitriles, aldehydes, and sodium azide. This elegant domino process involved consecutive iron-mediated [3 + 2] cycloaddition, copper-catalyzed SNAr, reduction, cyclization, oxidation, and copper-catalyzed denitrogenation sequences. The formed structure
已经开发了一种高效的Fe / Cu中继催化多米诺协议,用于从可商购的邻卤代苄腈,醛和叠氮化钠合成2-苯基喹唑啉-4-胺。这种优美的多米诺骨牌工艺涉及连续的铁介导的[3 + 2]环加成,铜催化的S N Ar,还原,环化,氧化和铜催化的脱氮序列。形成的结构是药物和生物活性分子中的特权核心。
