A new series of benzo[f]indazole derivatives was synthesized via cyclo-condensation of β-ketoester with arylidenes derivatives in the presence of alcoholic sodium hydroxide to afford octahydronaphthalene-2-carboxylates. 1,3-Dipolar cycloaddition between these carboxylates and hydrazine hydrate to form benzo[f]indazole derivatives. New obtained compounds were characterized upon elemental and spectroscopic analyses. Antibacterial activity of selected derivatives was evaluated.
