Ethyl 4-hydroxy-2,6-diphenyl-1-[2-(piperidin-1-yl)acetyl]-1,2,5,6-tetrahydropyridine-3-carboxylate

Abstract

In the title compound, C27H32N2O4, the piperidine and tetrahydropyridine rings adopt chair and half-chair conformations, respectively. The dihedral angle between the two phenyl rings is 32.9 (1)°. The molecular structure is stabilized by a strong intramolecular O—H...O hydrogen bond, generating an S(6) motif. In the crystal, intermolecular C—H...O interactions form a ribbon-like structure along the a axis.
