摘要

A simple and efficient method has been developed for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives through a one-pot three-component condensation reaction of 2-chloro-3-formyl quinolines, malononitrile/ethyl cyanoacetate and 2,3-dihydro-1,4-phthalazinedione using a catalytic amount of piperidine in refluxing ethanol. All the synthesized compounds were screened for their antibacterial activity against a panel of pathogenic strains of bacteria and fungi.
