Ethyl 1-benzoyl-4-hydroxy-2,6-diphenyl-1,2,5,6-tetrahydropyridine-3-carboxylate

Abstract

In the title compound, C27H25NO4, the tetrahydropyridine ring adopts a half-chair conformation. The three phenyl rings form dihedral angles of 66.33 (7), 87.36 (8) and 36.90 (7)° with the least-squares plane through the tetrahydropyridine ring. The molecular conformation is stabilized by an intramolecular O—H...O hydrogen bond, generating an S(6) motif.
