摘　　要：嘧啶芳基醚衍生物因具有多样的生物活性和药理学特性而受到化学家的广泛关注.利用2-(三甲基甲硅烷基)苯基三氟甲烷磺酸酯作为苯炔源,与2-羟基嘧啶发生加成反应,以中等至良好的产率合成了一系列2-芳氧基嘧啶类衍生物.与传统的方法相比,该方法具有无需过渡金属催化,嘧啶底物易于制备,底物官能团兼容性强和产物产率高等优点.Pyrimidine aryl ether derivatives have attracted widespread attention from chemists for their diverse biological activity and pharmacological properties.In this paper,a series of pyrimidine-2-arylether derivatives were synthesized with moderate to good yield by using 2-(trimethylsilyl)phenyl trifluoromethanesulfonate as a source of benzyne to react with 2-hydroxypyrimidine.Compared with the traditional method,this method has the advantages of transition-metal-free,easy preparation of 2-aryloxypyrimidine derivatives,wide functional group compatibility and high yield.
