A novel series of 1,4-benzoxazinone derivatives were synthesized and characterized using FT-IR , 1H-NMR, 13C-NMR and Mass spectroscopy. These compounds were in vitro screened against several bacterial species gram positive and gram negative as well as Candida albicans and found exhibiting moderate to potent activity. The antioxidant study was confirmed for the synthesized derivatives against 1,1‐d...
