In the title molecule, C22H20O5, the C=C bond of the central enone group adopts an E conformation. The dihedral angle formed by the benzene ring and the naphthalene ring system is 12.6 (4)°. The hydroxy group attached to the naphthalene ring is involved in an intramolecular O—H⋯O hydrogen bond. In the crystal, weak C—H⋯O hydrogen bonds link the molecules into chains along [010]. In addition, π–π stacking interactions are present, with centroid–centroid distances of 3.6648 (15) and 3.8661 (15) Å between the benzene and two naphthalene rings.

To a solution of 2,4,5-trimethoxybenzaldehyde (196 mg, 1 mmol) in 10 ml of ethanol was added 1-hydroxy-2-acetonaphthone (186 mg, 1 mmol) and the temperature was adjusted to around 275–276 K in an ice-bath. To the cooled reaction mixture 1 ml of 50% aqueous KOH solution was added, and the reaction mixture was stirred at room temperature for 20 h. This mixture was poured into iced water (30 ml) was acidified (pH = 3) with 6 N HCl solution to give a precipitate. Filtration and washing with water afforded crude solid of the title compound (180 mg, 48%). Recrystallization of the solid from ethanol gave yellow colored crystals (mp: 471–472 K).
The H atoms were placed in calculated positions with C—H = 0.95 and 0.98 Å or O—H = 0.84 Å, and refined in a riding-model approximation with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(Cmethyl) and Uiso(H) = 1.5 Ueq(O)].

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. |

Varieties of chalcones have been synthesized and isolated from natural sources, which have been used for evaluation of their pharmaceutical applications. They have showed diverse biological activities including anticancer (Shenvi et al. 2013), antidiabetic (Hsieh et al. 2012), antimicrobial (Sharma et al. 2012), anti-Leishmania (Aponte et al. 2010), anti-inflammatory (Sashidhara et al. 2011) and antitubercular (Hans et al. 2010). In continuation of our research interest to develop benzochalcone derivatives which show broad range of biological activities (Jo et al. 2012), titled compound was synthesized and its crystal structure was determined.
The molecular structure of the title compound is shown in Fig. 1. Chalcone is a family of flavonoid class which has a general C6—C3—C6 carbon framework and that of C3 is an α,β-unsaturated carbonyl (enone) group. One of the C6 is substituted with C10 (naphthalene ring) in the benzochalcone, where the titled compound belongs to. The C2═C3 bond of the central enone group adopts a trans configuration. The dihedral angle formed by the naphthalene ring system and the benzene ring is 12.6 (4)°. Due to an intramolecular O—H···O hydrogen bond between the hydroxy group of the naphthalene ring and carbonyl (C═O) group, the C1═O1 bond [1.262 (3) Å] is slightly longer than the standard value (Allen et al. 1987). In the crystal, weak C—H···O hydrogen bonds link the molecules into one-dimensional chains along [010] (Fig. 2). In addition, intermolecular π–π stacking interactions are present with Cg1···Cg2(1-x, 2-y, -z) = 3.6648 (15)Å and Cg1···Cg3(1-x, 2-y, 1-z) = 3.8661 (15)Å, where Cg1, Cg2 and Cg3 are the centroids of the C4/C5/C7/C8/C10/C12, C13/C14/C15/C20/C21/C22 and C15/C16/C17/C18/C19/C20 rings.
Examples of structures of substituted prop-2-en-1-one compounds have been published (Park et al., 2013; Fadzillah et al., 2012).
