The central β-lactam ring of the title compound, C36H24N2O4, is almost planar (r.m.s. deviation = 0.003 Å) and makes dihedral angles of 17.17 (19), 89.76 (17) and 78.44 (17)° with the benzene ring, the anthracene ring (r.m.s. deviation = 0.003 Å) and the 1H-benzo[de]isoquinoline-1,3(2H)-dione moiety, which is nearly planar [maximum deviation = 0.098 (2) Å], respectively. The molecular structure is stabilized by an intramolecular C—H⋯N hydrogen bond. In the crystal, molecules are linked via C—H⋯π and π–π stacking interactions [centroid–centroid distances = 3.5270 (19) and 3.779 (2) Å], forming a three-dimensional structure. A region of disordered electron density, probably disordered solvent molecules, was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9–18], which indicated a solvent cavity of 322 Å3 containing approximately 91 electrons. Their formula mass and unit-cell characteristics were not taken into account during the refinement.

1-(anthracen-9-yl)-N-(4-methoxyphenyl) methanimine (1 mmol), triethylamine (5 mmol), 2-(1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl) acetic acid (1.50 mmol) and tosyl chloride (1.50 mmol) were added to anhydrous CH2Cl2 (5 ml) and the mixture was stirred at room temperature for 24 h. The mixture was then washed with HCl 1N (2 × 20 ml), saturated aqueous NaHCO3 solution (50 ml) and brine (20 ml). The organic layer was dried (Na2SO4) and the solvent was removed in vacuo to give the product as a yellow solid. It was then purified by recrystallization from DMSO to afford yellow crystals (yield: 80%; m.p.: 458–460 K; IR (KBr, cm-1): 1751 (CO β-lactam),1704 (CO Naph), 1666 (CO Naph); 1H-NMR (250 MHz, DMSO-d6) δ: 3.57 (CH3 s, 3H), 6.73–6.79 (m, 4H), 6.97 (d, 2H, J = 2.5), 7.09 (aromatic d, 2H, J = 8.75), 7.49–7.57 (aromatic, m, 4H), 7.81–7.90 (aromatic, m, 2H), 8.16 (aromatic d, 2H, J = 7.75), 8.42–8.51 (aromatic, m, 6H), 8.51(aromatic s, 1H); 13C-NMR (62 MHz, DMSO-d6) δ 163.81 (CO β-lactam), 162.18 (CO Naph), 155.77, 134.93, 131.30, 131.18, 131.07, 130.96, 130.01, 129.84, 129.78, 127.52, 127.44, 127.25, 125.17, 124.14, 122.57, 121.41, 117.75, 114.55(aromatic carbons), 62.10 (C β-lactam), 55.58 (C β-lactam), 55.05 (CH3—O); GC—MS m/z = 548 [M+]; Analysis calculated for C36H24N2O4: C, 78.82; H, 4.41; N, 5.11%. Found: C, 76.53; H, 4.45; N, 5.81%.
H atoms attached to C atoms were positioned geometrically (C—H = 0.93 - 0.98 Å), and refined using a riding model with Uiso(H) = 1.5Ueq(C) for methyl H atoms and = 1.2Ueq(C) fro other H atoms. The crystal was of poor quality and did not diffract significantly at high 2θ angles, probably due to the presence of the disordered solvent molecules. 23 reflections were omitted owing to bad disagreement. A region of disordered electron density, most probably disordered solvent molecules, occupying voids of ca 322 Å3 for an electron count of 91, was removed with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as plausible solvent molecules. Their formula mass and unit-cell characteristics were not taken into account during 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. |

β-Lactams are a very important class of heterocyclic compounds due to their obvious biological activity (Von Nussbaum, et al., 2006). Because the β-lactam ring forms the main part of the penicillin structure, the β-lactam antibiotics have been the subject of much discussion and investigation (Soengas, et al., 2011). However, due to their extensive use common infections are once again becoming deadly (Fischbach & Walsh, 2009) and there is still a significant need for new research on β-lactams (Walsh & Wencewicz, 2014). Furthermore, β-lactams have been used in the synthesis of a wide variety of compounds which contain a nitrogen atom in their structures (Kim et al., 2014). In the past decades, a growing interest has been shown in the development of the various methods for the synthesis of β-lactams (Georg, 1992; Palomo et al., 2004; Ocampo & Dolbier, 2004). It has been observed that the most direct synthetic way to access β-lactam rings remains the formal [2 + 2] cycloaddition of ketenes and imines (Staudinger reaction) [Smith et al., 2014].
The β-lactam ring (N1/C1–C3) of the title compound, Fig. 1, is nearly planar [maximum deviation for atom N1 = 0.051 (2) Å]. It makes dihedral angles of 17.17 (19), 89.76 (17) and 78.44 (17)° with the benzene ring (C30–C35), the anthracene ring system (C16–C29) and the 1H-benzo[de]isoquinoline-1,3(2H)-dione (N2/O2/O3/C4–C15) moiety, respectively. The maximum deviations in the latter two ring systems are 0.050 (2) and 0.098 (2) Å, respectively.
All bond lengths and bond angles are normal and comparable with those reported for related compounds (Çelik et al., 2015; Butcher et al., 2011; Atioğlu et al., 2014; Jarrahpour et al., 2012; Jarrahpoor & Khalili, 2007; Jarrahpour & Ebrahimi, 2010). An intramolecular C—H···N hydrogen bond (Table 1) stabilizes the molecular conformation.
In the crystal, molecules are connected by C—H···π and π-π stacking interactions forming a three-dimensional structure; see Table 1 and Fig. 2 [Cg2···Cg3i = 3.5270 (19) and Cg6···Cg7ii = 3.779 (2) Å; where Cg2, Cg3, Cg6 and Cg7 are centroids of the N2/C4/C5/C10/C11/C15, C5–C10, C17–C22 and C24–C29 rings, respectively; symmetry codes: (i) -x+1, -y+1, -z+1; (ii) x, -y +1/2, z+1/2].
