摘要:
本文发展了一种由六氟磷酸铵提供铵源，与两分子α-氨基芳乙酮在醋酸银的氧化作用下，经过缩合、脱胺、环化等串联反应合成2-芳甲酰基咪唑衍生物的新方法。在最优条件下，合成了8种2-芳甲酰基咪唑衍生物，收率为52%~93%。所有的产物结构通过IR、NMR和MS等手段表征。该方法具有原料简单易得、操作简便等优点。
A new method for AgOAc-oxidative cyclization of α-aminoacetophenones with NH4PF6 leading to 2-arylformylimidazoles derivatives has been developed. Under the optimal reaction conditions, a wide range of 2-arylformylimidazoles derivatives were synthesized in moderate to good yields ranging from 52% to 93%. These products were confirmed by IR, NMR and MS. The results show that this method has advantages such as the availability for raw materials and simple chemical operations.
