A series of 2-fluoro-6H-chromeno[4,3-b]quinoline derivatives 2a~2d were synthesized by the Friedländer condensation of substituted (unsubstituted) o-aminobenzaldehyde with 6-fluorochroman-4-one in alkaline ethanol solutions. In addition, the expected products can give 2-(3-(ethoxymethyl)quinolin-2-yl)- 4-fluorophenol derivatives 3a~3d by nucleophilic substitution reaction in alkaline solutions. The structures of the title compounds 2a~2d and 3a~3d were characterized by elemental analysis, IR, 1H NMR and MS techniques. The compound 3d was confirmed by X-ray single crystal diffraction analysis.

Key words: Friedländer condensation, nucleophilic substitution reaction, 6-fluorochroman-4-one, crystal structure
