In this report a short and efficient synthesis of the dibenz[b,f]oxepin framework through intramolecular SNAr and McMurry reactions is described. The diaryl ethers required for the McMurry reaction have been obtained in good yields under microwave-assisted conditions of the reaction of salicylaldehydes with fluorobenzaldehydes without catalysts. Application of an intramolecular McMurry reaction to
在本报告中,描述了通过分子内 SNAr 和 McMurry 反应快速有效地合成 dibenz[b,f]oxepin 框架。McMurry 反应所需的二芳基醚在水杨醛与氟苯甲醛反应的微波辅助条件下,在没有催化剂的情况下以良好的收率获得。将分子内 McMurry 反应应用于在 THF 中使用 TiCl4/Zn 合成的二芳基醚以 53%-55% 的产率得到目标二苯并 [b,f]oxepin 系统。
