(Received 28 June 2012; accepted 3 July 2012; online 7 July 2012)

In the title compound, C33H32N2O2, the tetra­hydro­pyridine ring adopts a boat conformation with the carbonyl group in an s-cis conformation with respect to the C=C bond of the six-membered tetra­hydro­pyridine ring. The mol­ecular conformation is stabilized by intra­molecular N—H⋯O, C—H⋯O and C—H⋯π inter­actions. Formation of centrosymmetric head-to-head dimers is observed through pairwise inter­molecular N—H⋯O hydrogen bonds. Additional weak C—H⋯O and C—H⋯π inter­actions stabilize the three-dimensional mol­ecular assembly.

Comment top

Piperidine iminocyclitols have shown significant pharmacological results against HIV and in cancer therapy. Two deoxynojirimycin derivatives have already found clinical applications in treatment of type-II diabetes and Gaucher's disease (Pearson et al., 2005). Alkaloids containing the piperidine nucleus exhibited a promising wide range of biological activities such as antimicrobial, antiparasitic, cytotoxicity, anti-inflammatory, pesticidal and anti-HIV-1 properties (Sakai et al., 1986; Mishra & Ghosh, 2011). We have been investigating conformational and packing features of on tetrahyropyrimidine derivatives of compound (Nayak et al., 2011). In the extension of our recent work, we have been focusing on the synthesis and biological properties of piperidine analogues. Here, we determined and analyzed the single-crystal structure of the title compound

In the title molecule, the tetrahydropyridine ring adopts a boat conformation. The Cremer & Pople (1975) parameters are Q = 0.603 (2)Å, θ = 98.16 (15)° and φ = 65.53 (15)° respectively. The carbonyl group is in a s-cis conformation with respect to the CC bond of the six-membered tetrahydropyridine ring. The molecular conformation is stabilized by intramolecular N—H···O, C—H···O and C—H···π [C27—H27···Cg1 (centroid of C29—C34)] interactions (Fig.1, Table 1). Bifurcated N—H···O hydrogen bond patterns are observed with both intra- and intermolecular interactions. Pairwise intermolecular N—H···O interactions lead to formation of centrosymmetric head to head dimers (Fig. 2a). Further, weak C—H···O and C—H···π [C13—H13B···Cg2 (centroid of C7—C12); C21—H21C···Cg3 (centroid of C22—C27)] interactions stabilize the 3-dimensional molecular assembly (Fig. 2b).

Experimental top

To a mixture of p-toluidine (0.01 mol), methylacetoacetate (0.005 mmol), ZnCl2 (0.01 mol) and ethanol (10 ml) in a 50 ml round bottom flask was added benzaldehyde (0.01 mol). The reaction mixture was stirred at room temperature for 16 h, as monitored by TLC and then cooled to room temperature. The solid precipitate obtained was filtered and washed with aqueous ethanol to obtain a crude product (Yield 60 %; m. p. 222 (2) °C). Suitable crystals for X-ray analysis were grown from a mixture of ACN:THF (V/V;1:1) solvent by slow evaporation at room temperature.

Refinement top

All H atoms were positioned geometrically, C—H = 0.95 Å, 0.98 Å, 0.99 Å, 1.0 Å for aromatic, methyl, methylene and methine hydrogen respectively and N—H = 0.88 Å, and were refined using a riding model with Uiso(H)= 1.2 Ueq(C, N) for aromatic, methylene, methine and amine hydrogens, and 1.5 Ueq(C) for methyl H atoms respectively.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
