Abstract
2-Acetylbenzimidazole (1) on condensation with various aldehydes yields the chalcones (2a-1) which on cyclization with thiourea/urea in alc. KOH furnish the corresponding 2-imino-4-(benzimidazol-2'-yl)-6-aryl-6H-2,3-dihydro-1,3-thiazines/1,3-oxazines (3a-1, 4a-1). The compounds have been evaluated for their antibacterial and antifungal activities.
