An one-pot synthetic approach to the novel 3a,4,5,6-tetrahydro[1,2,4]oxadiazolo[4,5-a][1,5]benzodiazepine system, by 1,3-dipolar cycloaddition of benzonitriloxides to 1,5-benzodiazepine derivatives, is described. The structure and stereochemistry of the obtained adducts have been assigned by means of spectroscopic measurements.
通过1,3-偶极环加成苯并氮氧化物对一新的3a,4,5,6-四氢[1,2,4]恶二唑[4,5- a ] [1,5]苯并二氮杂系统进行一锅合成方法描述了1,5-苯并二氮杂卓衍生物。所获得的加合物的结构和立体化学已经通过光谱测量确定。
