An efficient, one-pot method for the synthesis of dibenzodiazepinone derivatives involving copper-catalyzed tandem C-N bond formation is reported. The use of various halo amide and 2-iodoaniline derivatives permitted the synthesis of an array of dibenzodiazepinone derivatives in moderate to good yields. Moreover, a dibenzodiazepinone derivative {2-(11-oxo-5H-dibenzo[b,e][1, 4]diazepin-10(11H)-yl)benzonitrile} was utilized to synthesize the triazapentacyclic ring derivative {12-chloro- 8,15,22-triazapentacyclo[13.7.0. 02,7.09,14.016,21]docosa-1(22),2,4,6,9(14),10, 12,16(21),17,19-decaene}.
