The crystal structure of the title compound, C~14~H~5~F~4~NO~3~, which was synthesized by the condensation of tetrafluorophthalic anhydride with 2-aminophenol, is stabilized by an intermolecular O—H...O hydrogen bond. The dihedral angle between the phthalimide and hydroxyphenyl planes is 56.88 (6)°.
The title compound, C 18 H 20 ClNO 2 , has been synthesized by the reaction of 4-chlorobenzaldehyde, Meldrum's acid, dimedone and CH 3 NH 3 Cl(NaOAc) in ethanol under microwave irradiation. The pyridone ring adopts a screw-boat conformation and the cyclohexenone ring an envelope conformation.
