Abstract top

The asymmetric unit of the title compound, C21H25NO3, contains two crystallographically independent molecules (A and B). In both molecules, the piperidine ring adopts a chair conformation, with the methoxyphenyl rings attached equatorially. The dihedral angle between the two benzene rings in molecule A is 73.79 (8)°; the corresponding value in molecule B is 77.71 (8)°. The molecules are linked by N-H...O hydrogen bonds. In addition, C-H...[pi] interactions are also found in the crystal structure.

Comment top

2,6-Disubstituted 4-piperidones have various biological and pharmacological activities (Dimmock et al., 1990; Mutus et al., 1989). The crystal structure of r-2,c-6-bis(4-chlorophenyl)-t-3-isopropyl-1-nitrosopiperidin-4-one has been reported, in which the piperidine ring adopts a chair conformation (Gayathri et al., 2008).

The asymmetric unit of the title compound, C21H25NO3, contains two crystallographically independent molecules A and B. In both molecules, the piperidine ring adopts a chair conformation, with the methoxyphenyl rings and one of the methyl groups attached equatorially. The dihedral angle between the two benzene rings in molecule A is 73.79 (8)°; the corresponding value in molecule B is 77.71 (8)°. Both molecules are nearly identical, the r.m.s deviation of an overlay of all non-hydrogen atoms being 0.127 Å. The molecules are linked by N1A—H1A···O4B hydrogen bonds. Furthermore, C25B—H25B···π, C32A—H32B···π and C5B—H52B···π interactions are also found in the crystal structure (Fig. 3, Table 1).

Experimental top

Anisaldehyde (24.2 ml, 0.20 mol), 3-methyl-2-butanone (10.7 ml, 0.10 mol) and ammonium acetate (7.7 g, 0.10 mol) were dissolved in 80 ml of distilled ethanol and heated over a boiling water bath, with shaking until a yellow colour developed, which changed to orange. The solution was left undisturbed for 14 h. The precipitated solid was filtered and purified by recrystallization from ethanol. The yield obtained was 72.4% (24.6 g).

Refinement top

Atoms H1A at N1A and H1B at N1B were located in a difference Fourier map and refined isotropically; N1A—H1A = 0.92 (2) Å and N1B—H1B = 0.87 (2) Å. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.95, 0.98, 0.99 and 1.00 Å for Csp2, methyl, methylene and methine C, respectively; Uiso(H) = kUeq(C), where k = 1.5 for methyl and 1.2 for all other H atoms.

Special details top

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 > 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.
