Dihydropyridine Ring

The title compound, C25H27NO4, has a flattened dihydropyridine ring. The benzene and phenyl rings are synclinal to one another, forming a dihedral angle of 49.82 (8)°; the axis of the biphenyl rings makes an 81.05 (9)° angle to the plane of the dihydropyridine ring. In the crystal, N—H...O hydrogen bonds link the molecules into chain motifs running along thea-axis direction. The chains are cross-linked by C—H...O interactions, forming sheet motifs running slightly off the (110) plane, together with an intermolecular interaction between head-to tail biphenyl groups, thus making the whole crystal packing a three-dimensional network. Intramolecular C—H...O hydrogen bonds are also observed.

In the title compound, C28H29N5O, the molecule adopts an approximate U-shape, a conformation imposed at least in part by an intramolecular π–π contact between the two five-membered rings, which display a centroid-to-centroid separation of 3.6522 (7) Å. The planes of these rings are inclined to one another by 66.12 (5)°. A weak intramolecular C—H...·N hydrogen bond is also found. The planes of the phenyl rings of the amine unit are inclined at a dihedral angle of 81.10 (4)°, while that of the 4,5-dihydrooxazole ring makes an angle of 11.74 (8)° with its phenyl substituent. The crystal packing is stabilized by C—H...N hydrogen bonds that form chains parallel to thebaxis. Several C—H...π(ring) contacts are also present.
