  Straightforward Access to Pyrazines, Piperazinones, and Quinoxalines by Reactions of 1,2-Diaza-1,3-butadienes with 1,2-Diamines under Solution, Solvent-Free, or Solid-Phase Conditions

  摘要：

  The preparation of tetrahydropyrazines, dihydropyrazines, pyrazines, piperazinones, and quinoxalines by 1,4-addition of 1,2-diamines to 1,2-diaza-1,3-butadienes bearing carboxylate, carboxamide, or phosphorylated groups at the terminal carbon and subsequent internal heterocyclization is described. The solvent-free reaction of carboxylated 1,2-diaza-1,3-butadienes with the same reagents affords piperazinones, while phosphorylated 1,2-diaza-1,3-butadienes yield phosphorylated pyrazines. The solid-phase reaction of polymer-bound 1,2-diaza-1,3-butadienes with 1,2-diamines produces pyrazines.

  construction of polyfunctionalized quinoxalines has been developed. The key strategy includes the one‐pot domino N−H insertion, cyclization, and oxidation reactions. This protocol offers a safe and mild synthetic approach to access a variety of quinoxaline derivatives in high yields. This methodology also allows the formation of biologically interesting pyrazines and benzoquinoxalines.

  已经开发了一种新颖，简便的铁催化水中邻苯二胺和重氮羰基串联的方法，用于构造多官能化喹喔啉。关键策略包括一锅多米诺骨牌NH插入，环化和氧化反应。该方案提供了一种安全，温和的合成方法，可以高产率获得各种喹喔啉衍生物。这种方法还可以形成生物学上有趣的吡嗪和苯并喹喔啉。
