Unsubstituted and 7- or 8-substituted 4-aryl-1H-1,5-benzodiazepin-2(3H)-ones 3a-t have been synthesized by the condensation of 3-aryl-5(4H)-isoxazolones 1a-e and parent 4-substituted 1,2-benzenediamines 2a-d under acidic conditions.
在酸性条件下,通过缩合 3-芳基-5(4H)-异恶唑酮 1a-e 和母体 4-取代的 1,2-苯二胺 2a-d 合成了未取代的和 7-或 8-取代的 4-芳基-1H-1,5-苯并二氮杂卓-2(3H)-酮 3a-t。
