Three new 1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one oximes were synthesized and characterized by the methods of 1H- and 13C-NMR, IR and elemental analysis. Along with previously described compounds bearing one additional methyl group on the 5th nitrogen atom, the new compounds were characterized in bulk by UV–Vis and fluorescence spectroscopy in various solvents. The influence of the nature
合成了三种新的1,3,4,5-四氢-2 H -1,5-苯并二氮杂-2-酮肟,并通过1H-和13C-NMR,IR和元素分析方法进行了表征。除了先前描述的在第5个氮原子上带有一个附加甲基的化合物外,这些新化合物还通过各种溶剂中的UV-Vis和荧光光谱进行了表征。研究并讨论了有机溶剂的性质对标题化合物光谱的影响。

20026 INTRODUCTION Benzodiazepines and their annelated derivatives ex-hibit a wide spectrum of biological activities andhave found applications in pharmaceutical chem-istry [1]. More recently, considerable efforts havebeen devoted to discover new biologically activecompounds in antitumor antibiotic group by the re-placement of the pyrrole fused ring of pyrrolo[2,1- c ][1,4]benzodiazepine system by thiazole
