A series of 3‐cyano‐2‐pyridone derivatives were synthesized by one‐pot four‐component condensationreaction involving a benzaldehyde derivative, alkyl cyanoacetate, acyclic or cyclicketones, and ammonium acetate in reflux condition. The X‐ray structure of the products 5a and 5d confirm symmetric dimers via hydrogen bonding interactions between individual pyridine molecules showing, in addition, also

antifungal, and antiviral activities. N‐propargyl and N‐allyl derivatives 23 and 25 showed significant anti‐SARS‐CoV. The N‐butylacetate and O‐allyl derivatives 18 and 26 showed potent antibacterial activities against both Gram‐positive (Staphylococcus aureus, Micrococci luteus) and Gram‐negative (Pseudomonas aeruginosa, Escherichia coli) bacterial strains. The N‐glucoside derivative 8 showed significant
