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.
