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 concise route for the synthesis of indenoisoquinoline derivatives from 2-iodobenzamide and 1,3-indanedione derivatives in the presence of copper(II) chloride and cesium carbonate in acetonitrile solvent is reported. A wide variety of 2-iodobenzamide derivatives and indandiones could be used to synthesize indenoisoquinoline derivatives and other fused indenoisoquinoline in moderate to good yields

In 2-iodo-N-(2-nitrophenyl)benzamide, C(13)H(9)IN(2)O(3), the molecules are linked into a three-dimensional framework structure by a combination of a C-H...O hydrogen bond, and iodo-nitro, carbonyl-carbonyl and aromatic pi-pi stacking interactions. In the isomeric compound N-(2-iodophenyl)-2-nitrobenzamide, the framework structure is built from N-H...O, C-H...O and C-H...pi(arene) hydrogen bonds and an iodo-nitro interaction.
