An efficient synthesis of imides has been developed through a Pd-catalyzed decarboxylative amidation of α-oxocarboxylic acids with secondaryamides. The reactions of N-substituted N-heteroarene-2-carboxamides with 2-oxo-2-arylacetic acids proceeded smoothly to generate the corresponding products in good yields in the presence of Pd(OAc)2 and K2S2O8.
通过α-氧代羧酸与仲酰胺的Pd催化脱羧酰胺化,已开发出一种有效的酰亚胺合成方法。在Pd(OAc)2和K 2 S 2 O 8的存在下,N-取代的N-杂亚芳基-2-羧酰胺与2-氧代-2-芳基丙烯酸的反应进展顺利,生成了相应的产物,收率很高。
