(Received 23 June 2010; accepted 6 July 2010; online 14 July 2010)

In the title compound, C27H32N2O4, the piperidine and tetra­hydro­pyridine rings adopt chair and half-chair conformations, respectively. The dihedral angle between the two phenyl rings is 32.9 (1)°. The mol­ecular structure is stabilized by a strong intra­molecular O—H⋯O hydrogen bond, generating an S(6) motif. In the crystal, inter­molecular C—H⋯O inter­actions form a ribbon-like structure along the a axis.

Comment top

Piperidine class of compounds is the valued heterocyclic compounds in the field of medicinal chemistry. We are interested in the title compound as similar type of derivatives have been found to exhibit remarkable antibacterial and antitumor properties (Aridoss et al., 2008, 2010). Recently, we have reported the crystal structures of few tetrahydropyridine derivatives (Aridoss et al., 2009a, 2009b). As part of our ongoing studies on establishing the conformation of the compounds through X-ray studies, we herein report the crystal structure of the title compound.

In the present structure, the piperidine ring adopts a chair conformation and the tetrahydropyridine ring is in a half-chair conformation. The sum of the bond angles around atoms N1 (357.8 (9)°) and N2 (329.6 (6)°) indicate sp2 and sp3 hybridizations, respectively. The puckering parameters (Cremer & Pople, 1975) and the smallest displacement asymmetry parameters (Nardelli, 1983) for the piperidine/tetrahydropyridine ring are q2 = 0.022 (3)/0.354 (4) Å, q3 = -0.572 (3)/0.293 (2) Å, QT = 0.572 (3)/0.459 (2) Å, and θ = 179.2 (3)/50.4 (2)°. The dihedral angle between the two phenyl rings is 32.9 (1)°. The piperidine and tetrahydropyridine rings are connected by the ethanone. The ethyl acetate group shows an extended conformation [C27—C26—O4—C25 = -116.4 (5)°]. The molecular structure is stabilized by a strong O—H···O hydrogen bond, wherein, atom O2 acts as a donor to O3, generating an S(6) motif.

Atoms C2 and C10 act as donors to form hydrogen bonds with atom O1 as an aceptor. In the crystal structure, the molecules at (x,y,z), (-x,-y,-z) and (1 - x,-y,-z) are linked into a ribbon-like structure along the a axis by C—H···O hydrogen bonds; the ribbons contain R22(12) and R22(16) ring motifs.

Experimental top

A mixture of piperidine (1 equiv.), N-chloroacetyl-3-carboxyethyl-2,6-diphenylpiperidin-4-one (1 equiv.) and anhydrous potassium carbonate (2 equiv.) in benzene was refluxed on an oil bath until its completion (Aridoss et al., 2010). The crude product obtained after usual work-up upon purification by column chromatography followed by re-crystallization in ethanol yielded fine crystals.

Refinement top

H atoms were positioned geometrically (O–H = 0.82 Å and C–H = 0.93–0.98 Å) and allowed to ride on their parent atoms, with 1.5Ueq(C) for methyl H and 1.2Ueq(C) for other H atoms.

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.
