“…2-pyridone is considered a privileged heteroaromatic skeleton endowed with pharmaceutical properties and biological activities [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. They are also widely applicable in organic synthesis, materials science, and polymer chemistry, which are used as valuable building blocks for the synthesis of nitrogen-containing heterocycles like pyridines, quinolizidines, β -lactams, piperidines, and indolizidine alkaloids [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Owing to their multifarious and prominent properties, 2-pyridones often display promising therapeutical areas such as antifungal, anti-HIV, antibacterial, antiepileptic, anti-inflammatory, and antitumoral activities [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ].…”
