Synthesis and spectral characterization of novel 1,5-benzodiazepine oxime derivatives

Abstract

Three new 1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-2-one oximes were synthesized and characterized by the methods of 1 Hand 13 C-NMR, IR and elemental analysis. Along with previously described compounds bearing one additional methyl group on the 5 th nitrogen atom, the new compounds were characterized in bulk by UV-Vis and fluorescence spectroscopy in various solvents. The influence of the nature of the organic solvent on the spectra of the title compounds was investigated and is discussed.
