We report here a simple and efficient copper catalyzed oxidative C–C bond cleavage of stable aromatic cyclic-fused and acyclic 1,2-diketones to deliver amides and imides in high yields. This newly developed protocol provides an excellent tool to transform structurally different 1,2-diketones into different products under the same reaction conditions. The key synthetic features of this methodology are
我们在这里报告了一种简单而有效的铜催化稳定的芳香族环状稠合和非环状1,2-二酮铜的氧化C–C键裂解,以高产率提供酰胺和酰亚胺的方法。该新开发的方案提供了一种出色的工具,可以在相同的反应条件下将结构不同的1,2-二酮转化为不同的产物。该方法的关键合成特征是高产量形成1,8-萘二甲酰亚胺和联苯-2,2'-二甲酰胺基序。还进行了1,8-萘二甲酰亚胺衍生物的荧光研究,以显示这些支架的潜在应用。
