Abstract:
Novel series of substituted 2-[3-(2,6-halophenyl)-5-methyl-isoxazolyl]-chromen-4-ones were synthesized by microwave irradiation method. The antioxidant activity of the synthesized compounds 5a-j was evaluated using free radical scavenging method (DPPH method) and reducing power assay. The antioxidant activity of synthesized chromenones with respect to the standard used, ascorbic acid is reported here
