Abstract top

The asymmetric unit of the title compound, C22H23F2NO, contains two independent molecules, A and B. The bicyclic system adopts a twin-chair conformation in both molecules. The dihedral angles between the fluorophenyl rings are 55.27 (8) and 56.37 (7)° in molecules A and B, respectively. The NH groups are not involved in hydrogen bonding due to the steric hindrance of fluorophenyl groups. The crystal structure features weak C-H...O interactions.

Comment top

In a continuation of structural studies of 1,5-dimethyl-3-azabicyclo[3.3.1]nonan-9-one derivatives (Venkateswaramoorthi et al., 2013), herewith we present the title compound, (I).

Figure 1 shows the asymmetric unit, which consists of two molecules A and B of the title compound (I). The bicyclo ring adopts the twin-chair conformation in both molecules, with puckering parameters Q = 0.598 (2) Å, θ = 177.73 (19)° and φ = 37 (4)° for the piperidine ring N1/C7···C11, and Q = 0.548 (2) Å, θ = 11.9 (2)° and φ = 61.6 (11)° for the cyclohexanone ring C8···C14 in molecule A. Corresponding parameters for molecule B are Q = 0.605 (2) Å, θ = 177.12 (19)° and φ = 326 (4)° for the piperidine N2/C37/C33/C34/C29/C38 and Q = 0.543 (2) Å, θ=11.2 (2)°, and φ = 299.7 (12)° for the cyclohexanone ring C29···C34 (Cremer & Pople, 1975).

The two fluorophenyl rings substituting positions at C7 and C11 in molecule A and at C37 and C38 in molecule B are planar and are oriented at an angle of 55.27 (8)° and 56.37 (7)° to each other, respectively. In molecule A, the piperidine ring makes a dihedral angle of 74.37 (6)° with the fluorophenyl ring C17···C22 and 64.37 (6)° with the fluorophenyl ring C1···C6, whereas in molecule B, the corresponding angles are 64.71 (6)° and 74.90 (6)° with the fluorophenyl rings C23···C28 and C39···C44, respectively.

The methyl groups attached to the piperidine ring at C8 and C10 in molecule A are in equatorial orientation with torsion angles of -174.75 (16)° (N1—C7—C8—C15) and 176.82 (16)° (N1—C11—C10—C16) respectively. In molecule B methyl groups attached to the piperidine ring at C29 and C33 are also in equatorial orientation, with torsion angles of 174.67 (6)° (N2—C38—C29—C35) and -177.52 (16)° (N2—C37—C33—C36).

In the crystal structure of a closely related structure (Venkateswaramoorthi et al., 2012), NH groups are involved in hydrogen bonding, but in the present case, the steric hindrance of fluorophenyl groups avoids the formation of these expected hydrogen bonds. Such a situation was previously reported in the same bicyclic system substituted by difluorophenyl rings (Pham et al., 1998)·In the asymmetric unit of the title compound, atom C18 of molecule A acts as a donor for a weak intermolecular interaction. In molecule B, C44 acts as a donor for a weak C—H···O interaction via H44 with O1 of an adjacent molecule (Table 1, Fig. 2).

Experimental top

Dry ammonium acetate (0.05 mol) was dissolved in ethanol (50 ml) and the solution was mixed with 4-fluoro-benzaldehyde (0.1 mol) and 2,6-dimethyl-cyclohexanone (0.05 mol). The mixture was first refluxed and then allowed to stand at room temperature overnight. Conc. HCl (30 ml) was added and the hydrochloride salt was collected and washed with a mixture of ethanol and ether (1:5 ratio). A suspension of the hydrochloride salt in acetone was treated with strong liquid ammonia solution and the free base was obtained by pouring water. The product was recrystallized from ethanol.

Refinement top

The methyl H atoms were constrained to an ideal geometry (C—H = 0.96 Å) with Uiso(H) = 1.5Ueq(C), but methyl groups were allowed to rotate freely about the C—C bonds. All remaining H atoms bonded to C atoms were placed in geometrically idealized positions (C—H = 0.93–0.98 Å) and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C). N1—H1A and N2—H2A bond lengths were constrained to 0.85 Å using DFIX, and bond length C33—C34 was restrained using DELU restraint (Sheldrick, 2008).
