(Received 4 May 2010; accepted 6 May 2010; online 12 May 2010)

In the structure of the title compound, C27H39N3O3, each of the (4-oxopiperidin-1-yl)methyl residues adopts a flattened chair conformation (with the N and carbonyl groups being oriented to either side of the central C4 plane) and they occupy positions approximately orthogonal to the central benzene ring [Cbenzene—C—Cmethyl­ene—N torsion angles 103.4 (2), −104.4 (3) and 71.9 (3)°]; further, two of these residues are oriented to one side of the central benzene ring with the third to the other side. In the crystal packing, supra­molecular layers in the ab plane are sustained by C—H⋯O inter­actions.

Comment top

Piperidin-4-one and their analogous pyran and thiopyran species attract interest owing to their biological properties, viz. anti-viral, anti-tumour (El-Subbagh et al., 2000), central nervous system (Ganellin et al., 1965), local anesthetic (Hagenbach et al., 1952), anti-cancer (Ileana et al., 1985), and anti-microbial (Mokio et al., 1989; Pathak et al., 2007) activities. As a continuation of structural studies of piperidine-4-ones (Vijayakumar et al., 2010), the title compound, (I), was synthesised and characterised by X-ray crystallography.

In compound (I), Fig. 1, the (4-oxopiperidin-1-yl)methyl residues containing the N1 and N2 atoms lie to one side of the central benzene ring and that with the N3 atom to the other. Owing to the presence of methyl substituents on either side of each 4-oxopiperidin-1-yl)methyl residue, the piperidin-4-one rings adopt side-on conformations to minimise steric interactions so that the N atoms occupy positions approximately normal to the plane through the benzene rings. This is quantified by the C2–C1–C7–N1 [103.4 (2) °], C2–C3–C14–N2 [-104.4 (3) °], and C4–C5–C21–N3 [71.9 (3) °] torsion angles. Each of the six-membered piperidin-4-one rings adopts a slightly flattened chair conformation with the N and carbonyl groups lying to either side of the central C4 plane in each case. Only the amine-N3 atom forms a significant intra- or inter-molecular interaction, i.e. an intramolecular C–H···N contact, Table 1. In the crystal packing, molecules are sustained into layers by C–H···O interactions; Table 1. Layers are formed in the ab plane and stack along the c axis, Fig. 2.

Experimental top

To a suspension of 1.5 equiv. of 4-piperidone hydrochloride monohydrate in benzene (20 ml), 3.0 equiv of K2CO3 was added. After stirring well for 30 min, 2,4,6-tris(bromomethyl)mesitylene (0.5 equiv) in benzene (10 ml) was added, followed by refluxing for 10 h. The completion of reaction was monitored by TLC. The reaction mixture was then allowed to cool to room temperature, filtered to remove the insoluble solids and then the filter cake was washed with dichloromethane. Excess solvents were removed under reduced pressure and the obtained crude product was purified by crystallization using 1:1 ratio of chloroform and methanol; m.pt. 483 K.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.96 to 0.97 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2–1.5Uequiv(C).

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.
