coupling of azine N-oxides and oxazoles has been developed. The C–C bond-forming process proceeds, accompanied by the removal of the oxygen atom from the azine core, to directly afford the azine–oxazole biaryl linkage. Moreover, this system requires no noble transition metals such as palladium and rhodium, which are common promotors in the related dehydrogenative couplings with the azine N-oxide. Thus, the
已经开发了一种铜介导的N-氮杂嗪和恶唑的形式上正式的脱水联芳基偶联。进行C–C键形成的过程,伴随着从嗪核心中除去氧原子,直接得到嗪-恶唑联芳基键。而且,该系统不需要贵族过渡金属,例如钯和铑,它们是与嗪N-氧化物相关的脱氢偶联中的常见促进剂。因此,本方案可以为药物和药物化学中备受关注的含嗪双杂芳基化合物提供独特且便宜的方法。
