Abstract
Novel 1,2-azaphosphole and 1,3,2-diazaphosphinines containing a chromene ring have been obtained from the treatment of 2-imino-2H-chromene-3-carboxamide (1) with some phosphorus halides. The compounds were evaluated for antioxidant and cytotoxic activities. Among the synthesized compounds, compound 4 exhibited the most potent antioxidant agents in comparison with ascorbic acid as standard antioxidant. Also, compound 4 recorded potentially cytotoxicity against all four cell lines.
