摘要

报道了一种利用一锅三组分反应合成新型阴离子合成子4-（2'，2-三甲基甲硅烷基乙炔基苯氧基甲基）-2H-甲烯-2-酮的有效方法。三甲基甲硅烷基乙炔、邻碘苯酚和九种不同的溴甲基香豆素在THF溶剂中于80°C下在密封管条件下反应，得到九种新的4-（2'，2-三甲基甲硅烷基乙炔基苯氧基甲基）-2H-甲烯-2-酮，分离产率大于90%。通过元素分析、FT-IR、MS、1H-和13C-NMR技术对所有化合物进行了光谱表征。

One-pot synthesis of a new class of alkynyl anionic synthons: the 4-(2',2-trimethylsilylethynylphenoxymethyl)-2H-chromen-2-ones

An efficient approach for the synthesis of a new class of anionic synthons: the 4-(2',2-trimethylsilylethynylphenoxymethyl)-2H-chromen-2-ones employing a one-pot three-component reaction is reported. Reaction of trimethylsilylacetylene, o-iodophenol and nine different bromomethylcoumarins in THF solvent at 80 °C under sealed tube conditions gave nine novel 4-(2',2-trimethylsilylethynylphenoxymethyl)-2H-chromen-2-ones in greater than 90% isolated yields. All compounds were spectroscopically characterized by elemental analysis, FT-IR, MS, ¹H-, and ¹³C-NMR techniques.
