A facile, efficient, and practical method for copper-catalyzed direct amination of maleimides and quinones with formamides in the presence of an oxidant KIO has been developed. It allows a facile access to a wide range of functionalized molecules with privileged scaffolds in drugs and natural products such as maleimides and quinones. A variety of substituted 3-amino-maleimides and 2-amino-quinones were synthesized with moderate to excellent yield.

在氧化剂 KIO3 存在下，铜催化马来酰亚胺和醌与甲酰胺的直接氧化胺化

开发了一种在氧化剂 KIO 存在下铜催化马来酰亚胺和醌与甲酰胺直接胺化的简便、高效且实用的方法。它可以轻松获得各种功能化分子，并在药物和天然产物（如马来酰亚胺和醌）中具有特殊的支架。合成了多种取代的3-氨基马来酰亚胺和2-氨基醌，产率中等至优异。
