One-Pot Four-Component Synthesis of Substituted N-Methyl 5-Охо-1,4,5,6,7,8-hexahydroquinoline-3-carboxamides. Biological Activity of the Obtained Compounds

A one-pot four-component solvent-free reaction of N-methyl acetoacetamide with dimedone, aromatic aldehyde and ammonium acetate leads to new substituted N-methyl 1,4,5,6,7,8-hexahydroquinoline-3-carboxamides. The structures of the products were proved using IR, 1H and 13C NMR spectroscopy. The synthesized compounds were tested for antimicrobial and antinociceptive activities. The resulting compounds have shown antinociceptive activity greater than that of metamizole sodium.
