(Received 16 May 2013; accepted 9 July 2013; online 20 July 2013)

In the title compound, C29H32N2O2, the piperidine ring exists in a chair conformation (the bond-angle sum at the sp2-hybridized C atom is 359.79°). The phenyl rings and the methyl group substituted on the heterocyclic ring are in equatorial orientations. In the crystal, pairs of C—H⋯π inter­actions result in the formation of inversion dimers.

Comment top

Piperdin-4-one nucleus is an important pharmacophore due to its broad spectrum of biological actions ranging from antibacterial to anticancer (Parthiban et al., 2009; 2011). Hence, the synthesis and steriochemical analysis of piperdin-4-one nucleus based pharmacophores has gained much interest in the field of medicinal chemistry.

The bond distances and angles in the title compound (Fig. 1) agree very well with the corresponding bond distances and angles reported in closely related compounds (Park et al., 2012a; 2012b). The piperidone ring (N1/C1—/C5) adopts a chair conformation with puckering parameters: Q =0.575 (2) Å, θ = 174.3 (2)° and ϕ = 359 (2)° (Cremer & Pople, 1975). The molecule exists in its E-isomeric form.

The packing of the molecules within the crystal is shown in Fig. 2. The crystal structure is stabilized by intermolecular C11—H11···Cg1i hydrogen bonding interactions resulting in centrosymmetric dimers about inversion centers, where Cg1 is the center of gravity of the ring atoms (C16—C21) (Table 1).

Experimental top

3-Isopropyl-2,6-diphenylpiperidin-4-one was synthesized by Mannich condensation using benzaldehyde (2 mol), ammonium acetate (1 mol) and isobutyl methyl ketone (1 mol) in absolute ethanol, warmed for 30 min and stirred overnight at room temperature. The product was treated with methyl iodide (1.5 mol) in the presence of potassium carbonate (2 mol) in acetone (10 ml) and refluxed for two hours yielding (4E)-1-methyl-3-isopropyl-2,6-diphenylpiperidin -4-one. The oximation was done by hydroxylamine hydrochloride (2 mol) in the presence of sodium acetate (2 mol) in ethanol (10 ml) and refluxed for two hours. The resulting oxime (0.5 g, 1.55 mmol) was stirred with dry pyridine (5 ml), added 3-methylbenzoic acid (0.23 g, 1.7 mmol) followed by the dropwise addition of phosphorus oxychloride (0.21 mL, 2.3 mmol) and stirred at ambient temperature for 15 min; the progress of the reaction was monitored by thin layer chromatography. Upon completion of the reaction, saturated sodium bicarbonate solution (8 ml) was added to the reaction mixture. The product was filtered and dried to get a white solid (0.62 g, 91%) which was recrystallized from ethanol to yield crystals suitable for X-ray crystallographic studies.

Refinement top

H atoms were positioned geometrically (C—H = 0.93–0.98 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.5Ueq(C) for methyl H and 1.2Ueq(C) for other H atoms.

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.
