This study demonstrates the efficient eco-friendly synthesis of a series of isoxazole derivatives 5a-h through (3+2) annulation of chalcones 3a-h and hydroxylamine (4) in citrus juice medium. The synthesized compounds were characterized by spectroscopic and CHN analysis, and assessed in vitro for their antioxidant susceptibilities by DPPH and hydroxyl radical scavenging assays. The result shows that compounds 5a, 5b, 5d and 5h have excellent DPPH and hydroxyl radical scavenging activity in both assays and therefore these molecule could serve as potent antioxidant agents.
