Antimicrobial evaluation of 3,1-benzoxazin-4-ones, 3,1-benzothiazin-4-ones, 4-alkoxyquinazolin-2-carbonitriles and N-arylimino-1,2,3-dithiazoles

Novel 3,1-benzoxazinones, 3,1-benzothiazinones and 4-alkoxyquinazolines have been synthesized viaN-aryl-1,2,3-dithiazoles derivatives. The antibacterial and antifungal activity of these compounds were measured; the dithiazoles are significantly active against fungi.
