Comment top

Piperidine heterocycles play an important role in the field of medicinal Chemistry (Balamurugan et al., 2006,2007). In the title compound, (I), N1 shows a pyramidal geometry (Fig. 1). The piperidine ring adopts a chair conformation. The phenyl group at C3 and the furyl rings at C2 and C6 are in equatorial positions. In the solid state, the symmetry-related molecules are linked by C23—H23···O4 (x + 1, -y + 1/2, z - 1/2) hydrogen bonds to form chains along the c axis (Fig. 2).

Experimental top

A mixture of ammonium acetate (38.5 g, 0.5 mol), furfuraldehyde (82.84 ml, 1 mol) and benzyl acetone (38.5 ml, 0.5 mol) in distilled ethanol was heated first to boiling. After cooling, the viscous liquid obtained was dissolved in ether (200 ml) and shaken with 10 ml of concentrated hydrochloric acid. The precipitated hydrochloride of 3-benzyl-2,6-di-furylpiperidin-4-one was removed by filtration and washed first with 40 ml mixture of ethanol and ether (1:1) and then with ether to remove most of the coloured impurities. The base was liberated from an alcoholic solution by adding aqueous ammonia and then diluted with water. It was recrystallized from mixture of petroleum ether. The yield of the compound was 70%.

Refinement top

Atom H1 at N1 was located in a difference Fourier map and refined isotropically. Remaining H atoms were positioned geometrically and allowed to ride on their parent atoms with C–H = 0.93–1.00 Å and Uiso = 1.2Ueq(parent atom). The furyl ring at position 6 is disordered. The site occupancy of the two atom positions C65A and C65B were refined (0.604:0.396).

Experimental. Solvent used: petroleum ether Cooling Device: Oxford Cryosystems Cryostream 700 Crystal mount: glued on a glass fibre Mosaicity (°.): 0.421 (1) Frames collected: 637 Seconds exposure per frame: 15 Degrees rotation per frame: 1.0 Crystal-Detector distance (mm): 35.0

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
