2-Oxo-2H-chromen-4-yl 4-methylbenzoate

A. Abou, A. Djandé, R. Kakou-Yao, A. Saba and A. J. Tenon

Abstract top

The asymmetric unit of the title compound, C17H12O4, consists of two independent molecules. The chromen-2-one ring and the 4-methylbenzoate side chain are inclined to one another at a dihedral angle of 64.79 (10)° in one molecule and 88.3 (1)° in the other. In the crystal, molecules form R22(8) centrosymmetric dimers via C-H...O hydrogen bonds. These dimers are stacked by C-H...O hydrogen bonds, resulting in R22(18) and R32(16) ring motifs. [pi]-[pi] stacking interactions between two parallel chromen-2-one rings, with centroid-centroid distances of 3.743 (1) and 3.771 (1) Å, are also present.

Comment top

Coumarins and their derivatives constitute one of the major classes of naturally occurring compounds and interest in their chemistry continues unabated because of their usefulness as biologically active agents. They also form the core of several molecules of pharmaceutical importance. Coumarin and its derivatives have been reported to serve as anti-bacterial (Basanagouda et al., 2009), anti-oxidant (Vukovic et al., 2010) and anti-inflammatory agents (Emmanuel-Giota et al., 2001). In view of their importance and as a continuation of our work on the crystal structure analysis of coumarin derivatives (Abou et al., 2011; 2012a,b), the title ester, (I), C17H12O5 has been synthesized and its molecular and crystal structure is reported herein.

The two independent molecules in the asymmetric unit of the title compound and the atomic labeling scheme are shown in Fig. 1. In these structures, the bond lengths in both independent molecules are comparable to those observed in related structures (Abou et al., 2011; 2012a,b). Also, the ten-membered chromen-2-one ring systems (O1A/C1A-C9A, O1B/C1B-C9B) of both independent molecules are essentially planar [the maximum deviation from planarity being respectively 0.014 (3) Å for atoms C2A and C4A (molecule A), and -0.010 (2) Å for atom O1B (molecule B)]. In the asymmetric unit, the two chromen-2-one ring systems are parallel displaced, as evidenced by the dihedral angle of 1.25 (7)° between them. In addition, the planar 4-methylbenzoate moieties of the two independent molecules are tilted with respect to one another with a dihedral angle of 26.14 (12)° between them. Furthermore, the angles between the chromen-2-one ring planes and the 4-methylbenzoate side chains of the two independent molecules are inclined at dihedral angles of 64.79 (10)° for molecule A and 88.3 (1)° for molecule B.

In the crystal, we observe the formation of R22(8) centrosymmetric dimers (Bernstein et al., 1995) between A and B molecules via C8A—H8A···O2B and C8B—H8B···O2A hydrogen bonds while two adjacent B molecules form similar rings through C2B—H2B···O1B contacts. The dimers are linked to each other by C12A—H12A···O2Ai and C12Ai–H12i···O2A hydrogen bonds to form an R22(18) ring motif and C5A–H5A···O4B, C8B—H8B···O2Ai and C12A—H12A···O2Ai contacts [symmetry operation i: - x, - y, - z] result in an R32(16) ring motif (Table 1, Fig.2). The supramolecular aggregation is completed by the presence of π···π stacking interactions between two parallel chromen-2-one rings; in the latter, the centroid···centroid distances, Cg1···Cg6 (x - 1, y, z) = 3.771 (1), Cg2···Cg5 = 3.7433 (13) Å, where Cg1, Cg2, Cg5 and Cg6 are centroids of the O1A/C1A/C6A-C9A, C1A/C2A-C6A, O1B/C1B/C6B-C9B and C1B/C2B-C6B rings respectively, are both less than 3.8 Å, the maximum regarded as reasonable for π···π interactions (Janiak, 2000) (Fig. 3).

Experimental top

To a solution of p-toluoyl chloride (40 mmole) in dried tetrahydrofuran (150 ml), was added dried triethylamine (120 mmole) and 4-hydroxycoumarin (40 mmole) in small portions over 30 min.The mixture was then refluxed for 3 h and poured into 300 ml of chloroform. The solution was acidified with dilute hydrochloric acid until the pH was 2 - 3. The organic layer was extracted, washed with water, dried over MgSO4 and the solvent removed. The crude product was recrystallized from a chloroform-acetone (1/3, v/v) mixture. Colourless crystals of the title compound were obtained in a good yield: 76%; M.pt. 393 K.

Refinement top

H atoms were placed in calculated positions [C—H = 0.93 (aromatic) or 0.96 Å (methyl group)] and refined using a riding model approximation with Uiso(H) constrained to 1.2 (aromatic) or 1.5 (methyl) times Ueq of the respective parent atom.

Special details top

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.
