(Anthracen-9-yl)(piperidin-1-yl)methanone

H.-Y. Hu, Y.-C. Huang, H.-T. Yu and Y. Zhang

Abstract top

The title compound, C20H19NO, is a substructure of CP-640186, a potent inhibitor of mammalian acetyl-coenzyme A carboxylases. In the crystal structure, the amide group forms a dihedral angle of 87.0 (1)° with the plane of the anthracene unit and the piperidine ring adopts a chair conformation. Molecules are arranged into layers parallel to (100) and adjacent anthracene units within layers form dihedral angles of 13.2 (1)°. C-H...O interactions from the piperidine rings to the C=O group of the amide are observed between layers.

Comment top

Inhibition of acetyl-CoA carboxylase (ACC), with its resultant inhibition of fatty acid synthesis and stimulation of fatty acid oxidation, has the potential to affect favourably the multitude of cardiovascular risk factors associated with the metabolic syndrome. Recent findings reported by Pfizer researchers show that the isozyme-nonselective ACC inhibitor CP-640186 inhibits both the lipogenic tissue isozyme (ACC1) and the oxidative tissue isozyme (ACC2) (Harwood et al., 2003). The title compound is a sub-structure of CP-640186 (see Zhang et al., 2004).

Experimental top

A mixture of 9-carbonyl anthracene (1 mmol) and piperidine (1.2 mmol) with 1.5 mmol DCC (DCC = N,N'-dicyclohexyl-carbodiimide) was stirred in 5 ml CH2Cl2 at room temperature for 1 h to yield the title compound. Crystals were obtained from acetone/petroleum ether.

Refinement top

H atoms were positioned geometrically and refined using a riding model with C—H = 0.93–0.97 Å and with Uiso(H) = 1.2Ueq(C).

Special details top

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.
