The molecule of the title compound, C24H18O10, a previously unknown coumarin derivative, contains methoxycarbonyl, 2-butenedioate and benzoyl groups aligned at angles of 28.04 (2), 76.89 (3) and 42.48 (13)°, respectively, to the plane of the coumarin ring system. Intramolecular O—H⋯O hydrogen bonding between hydroxy and carbonyl groups and weak intermolecular C—H⋯O hydrogen bonding is present in the The two carbon atoms and attached H atom of the ethylene bond are disordered over two positions, with site occupancy factors of ca 0.9 and 0.1.

To a magnetically stirred solution of 2,4-dihydroxy benzophenone (0.43 g, 2 mmol) and triphenylphosphine (0.52 g, 2 mmol) in 10 ml CH2Cl2 was added dropwise at 263 K over 10 min dimethyl acetylenedicarboxylate (0.45g, 2 mmol). The reaction mixture was then allowed to warm up to room temperature and stand for 48 h. The solvent was removed under reduced pressure and the residue was separated by silica gel

The hydroxyl H atom was located in a difference Fourier map and refined isotropically. Other H atoms were placed in calculated positions and refined in riding model with the Uiso(H) = 1.5Ueq(C) (methyl) or 1.2Ueq(C) (others). In absence of significant effects, Friedel pairs were merged.Data collection: SMART (Bruker, 1998); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Coumarin derivatives are used as laser dyes (Maeda, 1984). Some of them are found in natural products and exhibit antifungal and anticoagulant properties (Parrish et al., 1974; Troste & Toste, 1996). They have been found to possess a wide variety of uses in the perfumery industry, as avour enhancers, sunscreens, laser dyes (Khalfan et al., 1987) and in the pharmaceutical industry (Hooper et al., 1982; Morris & Russell, 1971). We have recently synthesized a series of 7-hydroxy coumarins based on a direct, efficient and operationally convenient approach. This paper reports the synthesis and structure of the title compound, which is one of the products of this reaction.
In the molecular structure (Fig. 1) of the title compound, atoms C10, C11 and H11A are disordered over two sites with occupancy ratio of 0.85:0.15. The inclinations of the planes of the metoxycarbonyl (defined by atoms O9-C23-O10-C24), hydroxy group (defined by atoms C3-O3-H3O), olefin (defined by atoms C12-C11-C10-C14) and benzoyl substituents (defined by atoms C16 to C22) with respect to the coumarin ring system are 28.04 (2), 12.1 (4), 76.89 (3) and 42.48 (13)°, respectively. Torsion angle between hydroxy group and carbonyl of benzoyl group is 0.7 (5)°. Therefore, these two groups are coplanar and form an intramolecular O-H···O hydrogen bonding. Torsion angle between olefin substituent and coumarin moiety is 106.0 (5)°. E-configuration was assigned to the geometry of olefinic bond on the basis of torsion angle of 176.8 (4)° between two methoxy carbonyl groups. Torsion angle between phenyl and carbonyl of benzoyl group is 140.9 (4)°. The crystal structure contains weak intermolecular C—H···O hydrogen bonding (Table 1).
