  描述：

  3-氟苄胺 、 7-benzyloxy-2-(3-benzyloxy-4-methoxyphenyl)-5-trifluoromethanesulfonyloxy-4H-chromen-4-one 以 N-甲基吡咯烷酮 为溶剂， 反应 0.17h， 以63%的产率得到7-benzyloxy-2-(3-benzyloxy-4-methoxyphenyl)-5-(3-fluorobenzylamino)-4H-chromen-4-one

  名称：

  A convenient microwave-assisted 5-amination of flavones

  摘要：

  A few examples of 5-aminoflavones' syntheses exist in the literature and for those, which are described, the amino group is introduced before the formation of the flavone skeleton. We describe here an efficient method, which permits the access to 5-aminoflavones by a simple procedure Using all SNAr amination under microwaves irradiation. (C) 2008 Elsevier Ltd.
