Chalcone Ditosylates as Potent Precursor for Synthesis of Some 4,5-Disubstituted Isoxazoles with Antioxidant and Anti-inflammatory Activities

The present work emphasizes on the synthesis of a series of 4,5-disubstituted isoxazole derivatives of α,β-chalcone ditosylates which were synthesized by the reaction of α,β-chalcone ditosylates with hydroxylamine hydrochloride. Various α,β-chalcone ditosylates were prepared by the reaction of respective chalcones with hydroxyl (tosyloxy)iodobenzene.The synthesized compounds were characterized and subsequently evaluated for anti-inflammatory and antioxidant properties.
