Abstract
In this work, a chalcone obtained from acetylcoumarin and vanillin was used as a starting compound for the synthesis of new effective antioxidants. A preparative method has been developed for the preparation of pyrazole and pyridine derivatives by the reaction of chalcone with hydrazine hydrate and malonodinitrile; the product yields were 29 and 61%. The synthesized substances were characterized by IR spectrometry, mass spectrometry and NMR spectroscopy. The antioxidant ability of the obtained substances was studied in comparison with 4-methyl-2,6-di-tert-butylphenol, including Fe-reducing ability and antiradical activity. The resulting compounds in both methods showed better results compared to the commercial antioxidant.
