Synthesis of New 3-(Furan-2-yl)-Substituted Dibenzo-Diazepin-1-one Derivatives: Synthesis of 3-(Furan-2-yl)-Substituted Dibenzo-Diazepin-1-ones

A new series of 3-(furan-2-yl) dibenzo-diazepin-1-one derivatives were synthesized by condensation of 5-(furan-2-yl)-1,3-cyclohexanedione, o-phenylenediamine, and aromatic aldehydes, in which in some of them existed two very close isomer compounds. All the compounds were characterized by IR, MS, 1H NMR, and elemental analysis. Also presented were the crystal structures of , and , which were obtained and determined by X-ray single-crystal diffraction.
