Abstract: Synthesis of 1,5-benzodiazepines derivatives was achieved by Diazotization of 7-aminocephalosporanic acid (1) with sodium nitrite in presence of mineral acid form diazonium salt (2). The resulting product (2) was treated with different β-diketones (3a-c) to form new derivatives of various β-diketones(4a-c). The derivatives of β-diketones(4a-c) are finally treated with o-phenylenediamine (o-PDA) to obtained 1,5-benzodiazepines derivatives, (5a-c). All the newly synthesized compound were characterized by elemental analysis and spectral studies.
