Methyl 2,6-diphenyl-1-p-tolyl-4-(p-tolyl- amino)-1,2,5,6-tetrahydropyridine-3- carboxylate

Abstract

In the title compound, C33H32N2O2, the tetrahydropyridine ring adopts a boat conformation with the carbonyl group in an s-cis conformation with respect to the C=C bond of the six-membered tetrahydropyridine ring. The molecular conformation is stabilized by intramolecular N-H...O, C-H...O and C-H...[pi] interactions. Formation of centrosymmetric head-to-head dimers is observed through pairwise intermolecular N-H...O hydrogen bonds. Additional weak C-H...O and C-H...[pi] interactions stabilize the three-dimensional molecular assembly.
