nitro group in nitrooximes by other nucleophiles was used to prepare various 2-(hydroxyimino)methyl- and 2-(methoxyimino)methyl-1,4-benzodiazepines. These compounds were converted to imidazo[1,5-a][1,4]benzodiazepines bearing a tertiary amine, methoxy or thiomethyl group in the 3-position.
其他亲核试剂取代硝基肟中的硝基被用来制备各种2-(羟基亚氨基)甲基-和2-(甲氧基亚氨基)甲基-1,4-苯并二氮杂s。这些化合物被转化为在3-位带有叔胺,甲氧基或硫代甲基的咪唑并[1,5- a ] [1,4]苯并二氮杂。
