Synthesis, biological evaluation and docking studies of novel benzopyranone congeners for their expected activity as anti-inflammatory, analgesic and antipyretic agents

8-Acetyl-7-hydroxy-4-phenyl-2H-benzopyran-2-one as starting material a number of 8-substituted derivatives (i.e., hydrazones 2a,b, imine 2c, chalcones 3, pyrazoles 4, 3-cyano-2-oxo-dihydropyridines 5, and/or 3-cyano-2-imino-dihydropyridines 6) were synthe

New Route to Synthesis of Some 8-(Dihydrocinnamoyl)dihydrocumarin Derivatives

The synthesis of 8-dihydrocinnamoyldihydrocoumarin derivatives starting from 8-acetyl-7-methoxy substituted coumarins involves: (i) aldol condensation with substituted benzaldehydes; (ii) partial demethylation of condensation products (AlCl3/acetonitrile)
