Antimicrobial Evaluation of 3,1‐Benzoxazin‐4‐ones, 3,1‐Benzothiazin‐4‐ ones, 4‐Alkoxyquinazolin‐2‐carbonitriles and N‐Arylimino‐1,2,3‐ dithiazoles.

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