Ethyl 4-anilino-2,6-bis­(4-fluoro­phen­yl)-1-phenyl-1,2,5,6-tetra­hydro­pyridine-3-carboxyl­ate

In the title compound, C₃₂H₂₈F₂N₂O₂, the tetra­hydro­pyridine ring adopts a distorted boat conformation. The two fluoro­phenyl groups are attached to the tetra­hydro­pyridine ring in a trans orientation. The dihedral angle between the planes of the fluoro-substituted rings is 57.0 (1)°. The amino group and carbonyl O atom are involved in intra­molecular hydrogen bonding. In the crystal, weak C—H...O, C—H...F and C—H...π inter­actions link the mol­ecules into columns along [010].

Methyl 4-(4-fluoro­anilino)-1,2,6-tris­(4-fluoro­phen­yl)-1,2,5,6-tetra­hydro­pyri­dine-3-carboxyl­ate

In the title mol­ecule, C₃₁H₂₄F₄N₂O₂, the tetra­hydro­pyridine ring adopts a distorted boat conformation. An intra­molecular N—H...O hydrogen bond is formed by the amino group and ccarboxyl C=O atom. The crystal structure features weak C—H...F and C—H...O inter­actions.

Ethyl 2,6-bis­(4-chloro­phen­yl)-4-(4-methyl­anilino)-1-(4-methyl­phen­yl)-1,2,5,6-tetra­hydro­pyridine-3-carboxyl­ate

In the title mol­ecule, C₃₄H₃₂Cl₂N₂O₂, the tetra­hydro­pyridine ring adopts a distorted boat conformation and both 4-chloro­phenyl substituents are in axial positions. An intra­molecular N—H...O hydrogen bond is formed by the amino group and carbonyl O atom. In the crystal, weak C—H...Cl inter­actions link the mol­ecules into chains along [010].

Ethyl 2,6-bis­(4-chloro­phen­yl)-4-(4-fluoro­anilino)-1-(4-fluoro­phen­yl)-1,2,5,6-tetra­hydro­pyridine-3-carboxyl­ate

In the title compound, C₃₂H₂₆Cl₂F₂N₂O₂, the tetra­hydro­pyridine ring adopts a distorted boat conformation. The chlorophenyl rings are inclined to one another by 55.2 (1)°, while for the fluorophenyl rings the dihedral angle is 80.7 (1)°. The amino group and carbonyl O atom are involved in an intra­molecular N—H...O hydrogen bond. In the crystal, weak C—H...O, C—H...F and C—H...Cl inter­actions link the mol­ecules into a three-dimensional network.
