4-Aryl-9,10-dihydronaphtho[2,1-b]-4H-pyran derivatives have been synthesized by the reaction of α,-unsaturated nitriles or α,-unsaturated carboxylate with 7-methoxy-1,2,3,4-tetrahydronaphtha- len-2-one catalyzed by KF/Al2O3. The structures of products were characterized by IR and 1H NMR spectra, and further confirmed by X-ray analysis.

Key words: synthesis, naphthopyran, KF/Al2O3
