AbstractAn efficient, one‐pot method for the synthesis of dibenzodiazepinone derivatives involving copper‐catalyzed tandem CN 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}.magnified image
