A dual removable activating group enabled Povarov reaction of N-arylalanine esters was reported. N-Arylalanine ester was utilized as the sole carbon source to generate N-arylimine and its tautomer, enamine, in situ by aerobic oxidation of sp3 C–H bonds, and then the consecutive reaction delivered the desired quinoline-4-carboxylate esters in high yields.
报道了使N-芳基丙氨酸酯具有双重可移动活化基团的Povarov反应。N-芳基丙氨酸酯是唯一的碳源,可通过sp 3 C–H键的需氧氧化原位生成N-芳基丙氨酸及其互变异构体烯胺,然后连续反应将所需的喹啉-4-羧酸酯高产。
