A novel one-pot synthesis of 7- chloro – 4 - phenyl - 3,4 - dihydro-2H- 1,3 - benzoxazin- 2- one derivatives [1a-1i] by condensation of a variety of aromatic aldehydes with p-chlorophenol and urea in the presence of wet cyanuric chloride under solvent free condition. All synthesized compounds were characterized on the basis of IR,NMR spectroscopic data and Elemental Analysis. All the compounds have been screened for antimicrobial activity by the cup-plate method. The results reveal that some of the synthesized 1,3-benzoxazine derivatives were exhibited good to moderate antibacterial and antifungal activity.
