Abstract top

In the title compound, C32H37NO3, the central dihydropyridine ring adopts a nearly planar flattened-boat conformation, whereas both cyclohexenone rings adopt half-chair conformations. The mean and maximum deviations from the mean plane of the dihydropyridine ring are 0.1252 (9) and 0.188 (1) Å, respectively. The 4-ethoxyphenyl and phenyl rings form dihedral angles of 75.20 (4) and 82.14 (5)° with the dihydropyridine mean plane, respectively.

Comment top

Acridine derivatives with a dihydropyridine unit belong to a special class of compounds, because of their wide range of applications in the pharmaceutical and dye industries. They are also well known as therapeutic agents (Wysocka-Skrzela & Ledochowski, 1976; Nasim & Brychcy,1979; Thull & Testa, 1994; Reil et al., 1994; Mandi et al., 1994).

The central dihydropyridine ring is almost planar with a mean deviation from the mean plane of 0.1252 (9) Å and with a maximum deviation of 0.188 (1) Å for C9. The planar 4-ethoxyphenyl and phenyl rings form dihedral angles of 75.20 (4)° and 82.14 (5)° with the dihydropyridine mean plane. The rings A (C1–C6), B (N1/C3/C4/C9/C10/C11) and C (C10–C15) show total puckering amplitudes Q(T) of 0.506 (2) Å, 0.307 (1) Å and 0.470 (2) Å, respectively. The cyclohexenone rings A and C adopt half chair conformation, whereas the central ring B adopts flattened boat conformation. This can be understood from the Cremer & Pople (1975) puckering parameters: φ = = -7.10 (2)° and θ = 62.2 (2)° (for A); φ = 166.5 (2)°, and θ = 77.4 (2)° (for B) and φ = -163.97 (3)°, θ = 56.9 (2)° (for C), respectively. In the title compound, the bond lengths (Allen et al., 1987) and angles are generally within normal ranges. In the dihydropyridine ring C10=C11 and C4=C3 are double bonds (C10—C11 = 1.3489 (18) Å and C4—C3 = 1.3540 (18) Å), as indicated by the bond distances. The C11—C10—C15 [120.39 (13)°] and C3—C4—C5 [119.51 (13)°] angles are almost the same. In this conformation C1 and C13 may be described as flap atoms being away from the plane of the ring. The observed carbonyl bond lengths (C15—O1 = 1.2232 (17) Å and C5—O2 = 1.2275 (17) Å) are also normal.

Experimental top

The title compound was prepared in two stages. In the first stage, a mixture of 4-ethoxybenzaldehyde (1.2 g, 8 mmol), 5,5-dimethylcyclohexane-1,3-dione (2.24 g, 16 mmol) and 20 ml of ethanol was heated to 70°C for about 10 minutes. The reaction mixture was allowed to cool to room temperature and the resulting solid intermediate, 2,2'-((4-ethoxyphenyl)methylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-enone) was filtered and dried (m.p.: 411 K, yield: 78%). In the second stage about 0.8 g of this intermediate was dissoloved in 25 ml of acetic acid. The solution was refluxed together with benzylamine (0.33 g, 3 mmol) for 8 h with the reaction being monitored by TLC. After completion of the reaction, the reaction mixture was poured into crushed ice and stirred well. The solid that separated was filtered and dried and then recrystallized from ethanol to yield yellow crystals of the title compound (m.p.: 433 K, yield: 82%).

Refinement top

All the hydrogen atoms were fixed in calculated positions and allowed to ride on their parent atom with d(C—H) = 0.96 Å and Uiso(H) = 1.5 Ueq(C) for CH3, d(C—H) = 0.97 Å and Uiso(H) = 1.2 Ueq(C) for CH2, d(C—H) = 0.98 Å and Uiso(H) = 1.2 Ueq(C) for aliphatic CH and with d(C—H) = 0.93 Å and Uiso(H) = 1.2 Ueq(C) for aromatic CH.

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.
