(Received 5 August 2010; accepted 11 August 2010; online 18 August 2010)

The title compound, C11H13NO4, contains a nitrone group, C=N—O—R, the geometry of which shows a Z configuration with near planarity (r.m.s. deviation = 0.0787 Å) around the C=N double bond. An intra­molecular C—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal packing, mol­ecules are linked into R22(12) dimers and R22(14) rings via C—H⋯O inter­molecular hydrogen bonds.

Comment top

Nitrones are important and versatile intermediates in organic synthesis since they undergo 1,3-dipolar cycloaddition reactions with a wide range of alkynes and alkenes to afford Δ2-isoxazolines (Mocours et al., 1995) and isoxazolidines (Gothelf & Jorgensen, 2000; Frederickson, 1997), respectively. Various cyclic or acyclic nitrones have been reported and found to be highly reactive intermediates as 1,3-dipoles (Merino, 2004). The cycloadducts have found numerous application in the synthesis of nucleosides (Merino et al., 1998), amino sugars (McCaig et al., 1998), pyrrollizideines (Desvergnes et al., 2005) and amino acids (Hanselmann et al., 2003). Nitrones are also useful intermediates for nucleophilic additions leading to the corresponding N,N-disubstituted hydroxylamines. Several types of nucleophile were used such as alkynes (Pillard et al., 2007), alkyl Grignard reagent (Merino et al., 2008) and enolates (Kobayashi et al., 2000).

The geometry of the nitrone molecule, which shows a Z configuration with near planarity around the C═N double bond [C8—N1 = 1.303 (2) Å], is typical for aldonitrones (Bedford et al., 1991; Kliegel et al., 1998; Olszewski & Stadnicka, 1995; Greci & Sgarabotto, 1984; Christensen et al., 1990). The torsion angles of O2—N1═C8—H8 and O2—N1═C8—C1 are 176.7 (3)° and -3.3 (3)°, respectively. These results are in good agreement with the literature (Merino et al., 1996; Olszewski & Stadnicka, 1995). An intramolecular C6—H6···O2 hydrogen bond generates an S(6) ring motif (Bernstein et al., 1995) (Fig. 1). In the crystal packing, molecules are linked into R22(12) dimers and R22(14) rings via C8—H8···O3 and C11—H11C···O2 intermolecular hydrogen bonds at (-1/2 + x, 1/2 - y, -z) and (-1/2 + x, -1/2 - y, -z), respectively (Table 1, Fig. 2). The benzene ring A (C1–C6) and S(6) rings are planar with the maximum r.m.s. deviation from the mean plane as -0.0234 (11) Å for N1 and these rings are coplanar with a dihedral angle of only 1.86 (10)°.

Experimental top

The title compound was synthesized by the literature method (Diez-Martinez et al., 2010). To a solution of methyl glycine ester hydrochloride salt (4.0 g, 31.8 mmol) in CH2Cl2 (70 ml) was added Et3N (4.4 ml, 31.8 mmol) and MgSO4 (2 g) under an argon atmosphere at room temperature. The resulting mixture was stirred for 2 h, then anisaldehyde (3.9 ml, 31.8 mmol) was added. The reaction mixture was stirred at room temperature for an additional 24 h. The resulting precipitate was filtered through a pad of Celite and the fitrate washed with water (50 ml) and brine (50 ml), then dried over MgSO4. Solvent was removed under reduced pressure. The title compound imine (1) was obtained as a white solid in 77% yield. The crude imine (1) (4.0 g, 19.3 mmol) was dissolved in MeOH (50 ml) and MgSO4 (2 g) was added as a drying agent. To this mixture UHP (urea-hydrogen peroxide) (5.5 g, 57.9 mmol) and MeReO3 (methyltrioxorhenium) (96 mg, 0.38 mmol) were added under argon atmosphere at room temperature. The reaction mixture was stirred at room temperature for 7 h. After 7 h the solvent was removed in vacuo, the residue was washed with more CH2Cl2 (3 × 50 ml) then filtered. The filtrate removed under vacuo and the residue subjected to column chromatography eluting with EtOAc/Hexane (1:1). The title compound was obtained as a pale yellow solid in 47% yield. m.p. 65–66°C.

Refinement top

The H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.97 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom). 915 Friedel pairs were averaged before the final refinement as the absolute structure could not be determined unambiguously.

Special details top

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.
