In the title compound, C22H18N2O5, the four-membered β-lactam ring is nearly planar, with a maximum deviation of 0.023 (2) Å for the N atom, and has long C—C distances of 1.525 (5) and 1.571 (5) Å. The mean plane of this group makes dihedral angles of 11.61 (19), 74.5 (2) and 72.3 (2)° with three aromatic rings. An intramolecular C—H⋯O hydrogen bond occurs. The packing of the molecules in the is governed mainly by intermolecular C—H⋯O hydrogen-bonding and C—H⋯π stacking interactions. Furthermore, a π–π interaction [centroid–centroid distance = 3.6129 (19) Å] helps to stabilize the crystal structure.

A mixture of N-(3-nitrobenzylidene)-4-methoxybenzeneamine (1.28 g, 5.00 mmol) and triethylamine (2.53 g, 25.00 mmol), phenoxyacetic acid (1.14 g, 7.50 mmol) and tosyl chloride (1.43 g, 7.50 mmol) in CH2Cl2 (30 ml) was stirred at room temperature overnight. Then it was washed with HCl 1 N, saturated sodium bicarbonate solution and brine, dried with Na2SO4 and the solvent was evaporated to give the crude product as a white crystal which was then purified by recrystallization from ethyl acetate (Yield 47%). [mp: 415° K]. IR (KBr, cm-1): 1739.7 (CO β-lactam). 1H NMR (250 MHz, CDCl3) δ 3.75 (Me, s, 3H), 5.48 (H-8, d, 1H, J = 4.75), 5.63 (H-9, d, 1H, J = 4.75), 6.75–8.23 (ArH, m, 13H); 13C NMR (62.9 MHz, CDCl3) δ 55.46 (Me), 61.02 (C-8), 81.01 (C-9), 114.62–156.83 (aromatic carbons), 161.86 (CO β-lactam); GC—MS m/z =390 [M+].
H atoms were placed in geometrically idealized positions [d(C—H) = 0.93 - 0.98 Å], and refined as riding with Uiso(H) = 1.2 Ueq(C) for methine and aromatic H atoms or 1.5Ueq(C) for methyl H atoms. The reflection 6 0 2 was omitted in final refinement.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

Azetidine-2-ones (β-lactams) were the first group of antibacterial natural products introduced as a therapeutic treatment of bacterial infections (Von Nussbaum et al.. 2006). The biological activity of β-lactams is mostly believed to be associated with the chemical reactivity of their β-lactam ring and on its substituents, especially at the nitrogen of the 2-azetidinone ring (Mehta et al. 2010). p-Anisidine derivatives have been found to be biologically interesting for many years (Jubie et al. 2009). Continuous change in the structures of known active compounds and the preparation of new types (Vatmurge et al. 2008) has been forced by the development of bacterial resistance to known compounds (Vatmurge et al. 2008).
In the title compound (I), (Fig. 1), the β-lactam ring (N1/C8–C10) is nearly planar, with a maximum deviation of 0.023 (2)Å for N1. The bond lengths in the β-lactam ring are comparable with those found in previous similar studies (Akkurt et al. 2006; Ercan et al., 1996a,b; Kabak et al., 1999).
Its mean plane makes dihedral angles of 11.61 (19), 74.5 (2) and 72.3 (2)°, respectively, with three aromatic rings (C1–C6), (C11–C16) and (C17–C22). The details of the dihedral angles between the planes of the rings are given in Table 2.
A weak intramolecular C—H···O hydrogen bond contributes to the stability of the molecular configuration (Table 1). The crystal structure is stabilized by intermolecular C—H···O hydrogen-bonding (Table 1, Fig. 2) and C—H···π stacking interactions (Table 1). Furthermore, a π-π interaction [Cg1···Cg3(x, y, z) = 3.6129 (19) Å, Cg1 and Cg3 are the centroids of the N1/C8–C10 β-lactam ring and the C11–CC16 benzene rings, respectively] helps to stabilize the crystal structure.
