The title compound, C 30 H 32 ClNO 3 , was synthesized by the reaction of dimedone with 4-methoxybenzaldehyde and 4chlorobenzenamine in water. The dihydropyridine ring is in a boat conformation. Both cyclohexene rings adopt envelope conformations. The chlorophenyl and methoxyphenyl rings form dihedr
The title compound, C 23 H 25 BrO 3 , was synthesized by the reaction of p-bromobenzaldehyde with dimedone and HClO 4 / SiO 2 in EtOH. In the molecule, the dihydropyran ring adopts a boat conformation and the two cyclohexene rings are in a trans conformation.
The asymmetric unit of the title compound, C 19 H 16 FN 5 O 4 , contains two independent molecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4) . Weakstacking interactions may be effective in the stabilization of the crystal
