The reaction of 2-acetylnaphtho[2,1-b]furan 1with different aromatic aldehydes afforded corresponding chalcones 2(a-f). These chalcones 2(a-f) on reacting with o-phenylenediamine in presence of a base produced 4-(naphtho[2,1-b]furan-2-yl)-2-(substituted)phenyl-2,5-dihydro-1H-1,5-benzodiazepines 3(a-f). The structures of newly synthesized compounds have been established by elemental analysis and spectral studies. Some of the newly synthesized compounds 3a-f exhibited potent antibacterial, antifungal, antiinflammtory, diuretic, anthelmintic and antipyreticactivities.
