SYNTHESIS OF DIHYDRO-4-OXOPYRROLO[1,2-B]PYRIDAZINE-3-CARBOXYLIC ACIDSAND DIHYDRO-4-OXOIMIDAZO[1,5-B]PYRIDAZINE-3-CARBOXYLIC ACIDS AS POTENTIAL ANTIBACTERIAL AGENTS

To check the antibacterial potential of two families of aza analogues of the quinolones, dihydro-4-oxopyrrolo[1,2-b]pyridazine-3-carboxylic acids and dihydro-4-oxoimidazo[1,5-b]pyridazine-3-carboxylic acids, we have prepared a few derivatives in theses families using N-aminopyrro le and N-aminoimidazole derivatives as starting building blocks and th e classical pathways of the quinolone series. The compounds showed no interesting antibacterial activity.
