取代水杨醛与5,5-二甲基-1,3-环己二酮(达米酮)在KF/Al2O3催化下反应生成一系列苯并吡喃的衍生物. 产物的结构通过红外光谱、核磁共振氢谱和元素分析进行表征, 并通过X单晶衍射分析进一步证实产物的结构.

关键词: 苯并吡喃, 水杨醛, 合成, KF/Al2O3

The benzopyran derivatives have been synthesized by the reaction of substituted salicylaldehydes with dimedone catalyzed by KF/Al2O3. The product structures 3 were characterized by IR, 1H NMR spectra and elemental analyses, and the structure of 3f was confirmed by X-ray analysis.

Key words: benzopyran derivative, KF/Al2O3, synthesis, salicylaldehyde
