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

A facile and rapid synthesis of isocoumarin derivatives using a copper-catalyzed tandem C–C/C–O coupling strategy from readily available substrates is described. The reactions of a wide range of 2-iodo-N-phenyl benzamides and acyclic diketones as starting materials were investigated.

The synthesis of quinazolinone derivatives was achieved from 2-iodobenzamide derivatives and various benzylamines, allylamine, and cinnamylamine derivatives through a one-pot copper-catalyzed reaction. In this reaction, the amine component (benzylamine/allylamine/cinnamylamine) is N-arylated with 2-iodobenzamide derivatives through Ullman coupling, followed by an intramolecular C–H amidation in the
