Ethyl 1-[2-(1H-benzotriazol-1-yl)acetyl]-4-hydroxy-2,6-diphenyl-1,2,5,6-tetrahydropyridine-3-carboxylate
Abstract
In the title compound, C28H26N4O4, the tetrahydropyridine ring adopts a boat conformation. The two phenyl rings form dihedral angles of 88.64 (8) and 59.28 (10)° with the best plane through the tetrahydropyridine ring. The dihedral angle between the two phenyl rings is 82.55 (10)°. The benzotriazole ring system is essentially planar, with a maximum deviation of 0.009 (1) Å from the least-squares plane. The molecular conformation is stabilized by an intramolecular O—H...O hydrogen bond, generating an S(6) motif.
