4-(2-Hydroxy­benzyl­idene)-3-methyl­isoxazol-5(4H)-one

Abstract

The mol­ecular skeleton of the title mol­ecule, C₁₁H₉NO₃, is approximately planar (r.m.s. deviation = 0.0056 Å); the two rings form a dihedral angle of 6.5 (1)°. In the crystal structure, inter­molecular O—H⋯N hydrogen bonds involving the H atom of the hydr­oxy group and the N atom of the isoxazole ring link mol­ecules into chains running along the c axis.

Comment

Arylmethylene isoxazolone derivatives are effective anti-psychotics in the treatment of depression and schizophrenia. The study about arylmethylene isoxazolone derivatives mainly concentrates in the biological activities (Ishioka et al., 2002; Liu et al., 2005). However, structural studies of them have rarely been reported. As a part of our investigation on arylmethylene isoxazolone derivatives, we report here the structure of the title compound, (I), synthesized by three component condensation reaction of methyl acetoacetate, hydroxylamine with salicylaldehyde in aqueous media under ultrasonic irradiation.

In (I) (Fig. 1), all bond lengths and angles agree well with those reported for the related compounds (Cocivera et al., 1976; Villemin et al., 1993; Zhang et al., 2008). The molecular structure adopts a Z-configuration about the C2=C5 double bond. The hydroxy groups and the isoxazol groups are involved in intermolecular O—H···N hydrogen bonds (Table 1), which link the molecules into chain structure, hydroxy O atom in the molecule acts as hydrogen-bond donor to isoxazol N atom in the neighbouring molecule, so forming a chain structure.

Experimental

A mixture of methyl acetoacetate (4 mol), hydroxylamine hydrochloride (4 mmol), and pyridine(4 mmol) in distilled water(10 ml) was irradiated in the water bath of an ultrasonic cleaner for 10 min., then salicylaldehyde(4 mmol) was slowly added to the mixture. The resulting mixture was irradiated in the water bath of an ultrasonic cleaner for 1.5 h. The solution was left at room temperature overnight, the obtained mushy solution was filtered and the solid was washed with cold water and ethanol. The crude product was recrystallized from ethanol to afford the desired product as a yellow solid. Single crystal of (I) were obtained by slow evaporation of aqueous ethanol(95%) solution at ambient temperature after 7 d. Elemental analysis, calculated for C11 H9 N O3: C 65.02, H 4.46, N 6.89%; found: C 65.09. H 4.49, N 6.92%.

Refinement

All hydrogen atoms were geometrically positioned (C—H = 0.93–0.96 A °, O—H = 0.82 A °) and allowed to ride on their parent atoms, with U_iso(H) = 1.2-1.5U_eq(C,O).

Special details

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.
