摘要
３┐酰化苯并吡喃衍生物的合成尹升镇（延边医学院药学系，延吉１３３０００）摘要报道了由邻羟基苯乙酮合成中间体二甲氨基－１－（２－羟基苯基）－１－丙烯酮，再与酸酐反应得３－酰化苯并吡喃－４－酮衍生物。经元素分析，核磁共振谱等证实其分子结构。关键词苯并吡喃...
We report a two step synthesis of 3 acylated 4H 1 benzopyran 4 ones in good yield through reaction of anhydrides a 3 (dimethylamino) 1 (substituted 2 hydroxyphenyl) propen 1 ones intermediate which is readily available from o hydroxy acetophenone. The structures of all these prepared compounds were characterized by elemental analysis and 1HNMR spectra.
