Abstract A simple synthesis of novel (E)-3-arylidene-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-ones from bromides of the Baylis--Hillman adducts using Fe/AcOH for the in situ reduction of nitro group, into an amino group, followed by the cyclization as a key step, has been described.
摘要 使用 Fe/AcOH 从 Baylis-Hillman 的溴化物中简单合成新型 (E)-3-亚芳基-2,3-二氢苯并[b][1,4] oxazepin-4(5H)-ones已经描述了硝基原位还原成氨基,然后环化作为关键步骤。
