In the title compound, C22H18O6, the dimeth­oxy-substituted naphthalene ring system is twisted relative to the 4H-chromenon skeleton by 88.96 (3)°. The two meth­oxy substituents are tilted from the naphthalene ring system by 1.4 (4) and 113.0 (2)°, respectively. An intra­molecular O—H⋯O hydrogen bond closes an S(5) ring motif. In the crystal, pairs of O—H⋯O hydrogen bonds form inversion dimers with R22(10) loops and C—H⋯O inter­actions connect the dimers into [010] chains.

Introduction top

Flavonols, such as Quercetin, Aza­leatin and Kaempferol, are a class of flavonoids that have a 3-hy­droxy­flavone backbone. Because of their wide spectrum of biological activities (Burmistrova et al. 2014, Dias et al. 2013), variety of flanonols have been isolated from natural sources and synthesized (Bendaikha et al. 2014; Prescott et al. 2013). In addition, they have been used as fluorescent probes for sensing and imaging due to their dual fluorescence. The fluorescence of flavonols has been shown to be related to the angle between the 4H-chromene-4-one moiety and the attached aromatic ring (Klymchenko et al. 2003). Our research project has been focused on development of novel flavonols which show broad range of biological activities (Lee et al. 2014), therefore the title compound was synthesized and its crystal structure was determined. A starting material, chalcone (III), was prepared by the previously reported methods (Yong et al. 2013). Flavonol was obtained by oxidative cyclization of the chalcone (III) with H2O2 in alkaline methanol medium (Fig. 3). In the title compound, C22H18O6, angle between the di­meth­oxy-substituted naphthalene ring and the 4H-chromenon skeleton is 88.96 (3)°, which shows they are almost orthogonal each other. In our previous report on flavonol (Yoo et al., 2014), the angle between 4H-chromenon and benzene ring is 5.2 (4)°. The meth­oxy groups in naphthalene ring at C12 and C13 are tilted from naphthalene ring by 1.4 (4)° and 113.0 (2)°, respectively. Meth­oxy group at C12 (meta position) lies almost in the same plane of naphthalene ring. Meth­oxy group at C13 (ortho position), however, is twisted away from the plane of naphthalene ring. An intra­molecular O—H···O hydrogen bond closes S(5) ring motif. In the crystal, pairs of O—H···O hydrogen bonds form inversion dimer with graph-set notation R22(10) and C—H···O inter­actions connect the dimers into [010] chains. Examples of structures of flavonols have been published (Narita et al., 2015; Serdiuk et al., 2013).

Experimental top

Equivalent amount of 2-hy­droxy-5-meth­oxy­aceto­phenone (I, 10 mmol, 1.66 g) and 2,3-di-meth­oxy­naphthaldehyde (II, 10mmol, 2.16 g) were dissolved in 20 mL of methanol and the temperature was adjusted to around 2-4 °C in an ice-bath. To a cooled reaction mixture was added 2 mL of 50% (w/v) aq. KOH solution and stirred at room temperature for 20h. At the end of the reaction, ice-water was added to the mixture and acidified with 3N HCl (pH = 3-4). The precipitation was filtered under vacuum and washed with methanol to give chalcone compound III (yield : 48 % , m.p : 407-408K). The chalcone compound (III, 1 mmol, 364 mg) was dissolved in 6 mL of methanol and 4 mL of THF. The reaction was cooled in a water-ice bath (2-4 °C) and a cold solution of 16% sodium hydroxide (1 mL ) was added with stirring. After 10 min, to the reaction mixture was added 2 mL of 35% H2O2. The end point of reaction was monitored by TLC. After completion of reaction, the reaction mixture was acidified with 3N HCl (pH = 4-5). The pale yellow precipitate obtained was filtered and washed with ethanol to give the titled compound (66%). Recrystallization in the ethanol solvent gave crystals (mp: 573-574K)

Refinement top

The H atoms were placed at calculated positions and refined as riding with C–H = 0.95 A [Uiso(H) = 1.2 Ueq(C)].

Special details top

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.
