The nucleus of 2-pyridone occurs widely in the structures of biologically natural alkaloids [1]. Many derivatives of 2-pyridone are frequently used as intermediates for the construction of alkaloids [2]. Even some derivatives of 4, 6-diaryl-2-pyridone, such as the simple structural related 2-pyridones, are recognized as potent LTB4 antagonist [3]. Numerous methods [4] have been reported for the synthesis of 2-pyridone derivatives, because of the biological ...
