Synthesis of new 3-phenyl substituted dibenzo-1,4-diazepin-1-one derivatives

摘要

A new series of 3-phenyl substituted dibenzo-1,4-diazepin-1-one derivatives were synthesised by condensation of 5-phenylcyclohexane-1,3-dione, o-phenylenediamine and benzaldehydes. All the compounds were characterised by IR, MS, H-1 NMR and elemental analysis. The crystal structure of 3-phenyl-11-(2-chlorophenyl)-2,3,4,5,10,11-hexahydro-1H-dibenzo[b,e] [1,4]diazepin-1-one was determined by X-ray single-crystal diffraction.
