“…1 Therefore, the development of various synthetic methods to obtain this compound and its derivatives has become of great importance for organic chemists. 2 A cyclization reaction, with or without metals, is one way to produce N -alkylated 2-pyridones, which are starting materials devoid of pyridine and pyridone rings. 3 In addition to these techniques, methods such as migration, alkylation, addition, and rearrangement of the derivatives of pyridine and pyridone are commonly used to produce this skeleton.…”
