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
