✦ Synopsis

The title compound, C 22 H 18 FNO 3 , was synthesized by the reaction of 1-naphthol with ethyl cyanocaetate and 4-fluorobenzaldehyde in ethanol under microwave irradiation. The pyran ring adopts a flattened envelope conformation. The molecular conformation and the crystal structure are stabilized by N-HÁ Á ÁO hydrogen bonds.
