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 the a-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.

Hantzsch 1,4-di­hydro­pyridines (DHPs) are an extensively studied class of compounds that are known predominantly for their L-type voltage gated calcium channel modulation. (Bossert et al. 1981, Triggle 2003) There have been extensive structure-activity relationship (SAR) studies done on DHPs that have revealed the basic structural requirements for robust binding affinity to calcium channels. (Triggle 2003) Other studies in the field have shown that DHPs bind to multiple receptors, most notably the multiple drug resistant protein 1 (MDR1) (Abe et al. 1995, Cole et al. 1989, Tasaki et al. 1995, Vanhoefer et al. 1999, Tolomero et al. 1994, Cindric et al. 2010). Using established SAR more selective compounds can be designed for greater selectivity resulting in more clinically relevant compounds.

The title compound, C25H27NO4, has very similar structural features as other DHPs. Such features include a flattened boat conformation of the 1,4-DHP ring and two ester groups coplanar to the double bonds in the 1,4-DHP, with one carbonyl being cis and the other carbonyl being trans to the double bonds (Figure 1). Although the phenyl group attached at C(3) is still orthogonal to the bottom [C(1)—C(2)—C(4)—C(5)] of the 1,4-DHP ring [81.05 (9)°], it twists away from the N(1)—C(3) at an angle of 47.77 (8)°. The next phenyl ring twists again, with 49.82 (8)° from the center phenyl group, and becomes almost orthogonal to the N(1)—C(3) axis [12.97 (9)°]. Inter­molecular hydrogen bonds between N(1) – H(1) and O(3), together with the inter­molecular C(6) – H(6) ··· O(3) inter­actions, link the molecules into chain motifs running along the a axis (Figure 2). Two inter­molecular C – H ··· O inter­actions both from O(2) cross link the molecules into sheet motifs running slightly off the 110 plane (Figure 3). These inter­ations form a three-dimensional network in the cyrstal packing (Figure 4). There are two intra­molecular H-bonds observed in the molecule, C(19) – H(19) ··· O(1) and C(13) – H(13B) ··· O(2).

Experimental top

Synthesis and crystallization top

An oven-dried 100 mL round bottom flask was charged with 1.90g of bi­phenyl-4-carbaldehyde, 2.86 g of ethyl aceto­acetate, 2.49 mL of 14.8M ammonium hydroxide, and a magenetic stir bar. The mixture was taken up in 50 mL of absolute ethanol, and the round bottom flask was fitted with a dean stark trap and heated to reflux while stirring. Reaction progress was monitored via TLC. Once the reaction was complete, excess solvent was removed via rotary evaporation. The solution was then purified via a silica column chromatography. The product was re-crystallized into white to yellow crystalline clumps with hexane and di­chloro­methane (yield = 1.24g , 3.06 mmol, 29.31%).

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. The methyl H atoms were constrained to an ideal geometry, with C – H = 0.98 Å and Uiso(H) = 1.5Ueq(C), and were allowed to rotate freely about the C – C bonds. The rest of the H atoms were placed in calculated positions with C – H = 0.95 ~ 1.00 Å and refined as riding on their carrier atoms with Uiso(H) = 1.2Ueq(C). The positions of amine H atoms were determined from difference Fourier maps and refined freely along with their isotropic displacement parameters. One low-angle reflection was omitted from the refinement because its observed intensity was much lower than the calculated value as a result of being partially obscured by the beam stop.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
