Novel tricyclic substituted 5,6-dihydro-4H-[1,2,4]oxadiazolo[4,3-a][1,5]benzodiazepin-1-one derivatives were prepared by the thermal intramolecular cyclization of tetrahydro-1,5benzodiazepin-2-one O-(ethoxycarbonyl)oximes. The latter were obtained from the corresponding hydroxyimino-1,5-benzodiazepines and ethyl chloroformate.
通过四氢-1,5苯并二氮杂环热分子内环化制备新型三环取代的5,6-二氢-4H-[1,2,4]恶二唑并[4,3-a][1,5]苯并二氮杂-1-酮衍生物-2-one O-(乙氧基羰基)肟。后者是从相应的羟基亚氨基-1,5-苯二氮卓类和氯甲酸乙酯中获得的。
