以2-羟基-2-三氟甲基-2H-苯并吡喃-3-甲酸乙酯类化合物为原料, 在微波辅助和无溶剂的条件下进行再成环反应, 合成了一系列3-三氟乙酰基香豆素类化合物. 该方法具有反应时间短、产率高(73%~88%)、操作简单和环境友好等优点. 产物结构使用IR、NMR、HRMS和X射线单晶衍射仪进行确定.

关键词: 微波, 3-三氟乙酰基香豆素, 再成环反应, 无溶剂

A series of 3-(trifluoroacetyl)coumarins were synthesized by recyclization of ethyl-2-hydroxy-2-trifluoromethyl-2H-chromene-3-carboxylates under microwave assisted solvent-free conditions. This method has the advantages of short reaction time, high yields (73%~88%), easy operation and environmental friendliness. The synthesized compounds were characterized by IR, NMR, HRMS and X-ray studies.

Key words: microwave, 3-(trifluoroacetyl)coumarins, recyclization, solvent-free
