A rapid and efficient synthesis of amino-substituted 2-pyridones was demonstrated by palladium-catalyzedamination reaction under microwave irradiation. This high-speed synthesis provided a number of amino-substituted 2-pyridones from the corresponding bromo-2-benzyloxypyridines viapalladium-catalyzedamination followed by hydrogenolysis of benzyl ether.
Copper catalyzed 1,2-diol promoted amination at electron-rich C-5 position of unprotected 2-amino/2-hydroxy-5-halopyridine and selective amination at C-5 in 2-bromo-5-iodopyridine provided excellent yields.
