Nucleophilic substitution of hydrogen followed by intramolecular electrophilic aromatic substitution in nitro drevitavies of indazole has been used as a key step in the one pot synthesis of newfluorescent heterocyclic compounds 3H-pyrazolo[4,3-a]acridin-11-carbonitriles.

The new heterocyclic system isoxazolo[4,3-e]indazole was synthesized via the nucleophilic substitution of a hydrogen in 1-methyl-5-nitro-1H-indazole with different aryl acetonitriles in basic medium. The fluorescence properties and antibacterial activities of the new compounds against Gram-positive and Gram-negative bacterial species were also studied.
