摘　　要：在KF/Al2O3催化下,α,β-不饱和腈或α,β-不饱和羧酸酯和7-甲氧基-1,2,3,4-四氢-2-萘酮反应,生成了一系列4-芳基-9,10-二氢萘并[2,1-b]-4H-吡喃衍生物.产物的结构通过红外光谱和核磁共振氢谱进行表征,并通过X单晶衍射分析进一步证实产物的结构.4-Aryl-9,10-dihydronaphtho[2,1-b]-4H-pyran derivatives have been synthesized by the reaction of a,fl-unsaturated nitriles or α,β-unsaturated carboxylate with 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one catalyzed by KF/Al203. The structures of products were characterized by IR and ^1H NMR spectra, and further confirmed by X-ray analysis.
