Abstract:
The title com-pound, C24H24N2O6, consists of ethyl 2-(1,2,3,4-tetra-hydro-2-oxo-quinolin-1-yl)acetate and 4-[(2-eth-oxy-2-oxoeth-yl)(phen-yl)carbomoyl] units, where the oxo-quinoline unit is almost planar and the acetate substituent is nearly perpendicular to its mean plane. In the crystal, C-HOxqn⋯OEthx and C-HPh-yl⋯OCarbx (Oxqn = oxoquinolin, Ethx = eth-oxy, Phyl = phenyl and Carbx = carboxyl-ate) weak hydrogen bonds link the mol-ecules into a three-dimensional network sturucture. A π-π inter-action between the constituent rings of the oxo-quinoline unit, with a centroid-centroid distance of 3.675 (1) Å may further stabilize the structure. Both terminal ethyl groups are disordered over two sets of sites. The ratios of the refined occupanies are 0.821 (8):0.179 (8) and 0.651 (18):0.349 (18). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (53.9%), H⋯O/O⋯H (28.5%) and H⋯C/C⋯H (11.8%) inter-actions. Weak inter-molecular hydrogen-bond inter-actions and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) geometric optimized structures at the B3LYP/6-311G(d,p) level are com-pared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO mol-ecular orbital behaviour was elucidated to determine the energy gap.

Crystal structure, Hirshfeld surface analysis and DFT studies of ethyl 2-{4-[(2-eth­oxy-2-oxoeth­yl)(phen­yl)carbamo­yl]-2-oxo-1,2-di­hydro­quinolin-1-yl}acetate

Chemical context

In recent years, research has been focused on existing mol­ecules and their modifications in order to reduce their side effects and to explore their other pharmacological properties. Quinolone derivatives have constituted an important class of heterocyclic com­pounds which, even when part of a com­plex mol­ecule, possesses a wide spectrum of biological activities, such as anti­cancer (Elderfield & Le Von, 1960), anti­fungal (Musiol et al., 2010), anti­tubercular (Fan et al., 2018a; Xu et al., 2017), anti­malarial (Fan et al., 2018b; Hu et al., 2017), anti-HIV (Sekgota et al., 2017; Luo et al., 2010), anti-HCV (Manfroni et al., 2014; Cheng et al., 2016) and anti­microbial (Musiol et al., 2006). They have been developed for the treatment of many diseases, like malaria (Lutz et al., 1946) and HIV (Ahmed et al., 2010). As a continuation of our research work devoted to the development of N-substituted quinoline derivatives and the assessments of their potential pharmacological activities (Filali Baba et al., 2016a, 2017, 2019; Bouzian et al., 2018, 2019a), we report herein the synthesis and mol­ecular and crystal structure of the title com­pound, along with the Hirshfeld surface (HS) analysis and density functional theory (DFT) com­putational calculations carried out at the B3LYP/6-311G(d,p) level of an N-substituted quinoline derivative by an alkyl­ation reaction of ethyl bromo­acetate with 2-oxo-N-phenyl-1,2-di­hydro­quinoline-4-carboxamide under phase-transfer catalysis conditions using tetra-n-butyl­ammonium bromide (TBAB) as a catalyst and potassium carbonate as a base.

Structural commentary

The title mol­ecule is com­posed of ethyl 2-(1,2,3,4-tetra­hydro-2-oxoquinolin-1-yl)acetate and 4-[(2-eth­oxy-2-oxoeth­yl)(phen­yl)carbomo­yl] units (Fig. 1). The mean planes of the constituent rings, i.e. A (atoms N1/C1–C4/C9) and B (C4–C9), of the oxo­quinoline unit are oriented at a dihedral angle of 1.04 (6)°. Thus, they are almost coplanar, with a maximum deviation of 0.017 (3) Å for atom C7. Atoms O1 and C10 deviate only by 0.007 (2) and 0.022 (2) Å from that plane and so are essential coplanar. The acetate substituent is nearly perpendicular to that plane, with a torsion angle of C1—N1—C10—C11 = −104.8 (2)°. The mean plane of the phenyl ring, C (C19–C24), is oriented with respect to the oxo­quinoline unit at a dihedral angle of 68.17 (6)°. The carboxyl groups, O5/O6/C11 and O3/O4/C16, are twisted out of coplanarity with the best least-squares plane of the oxo­quinoline unit and phenyl ring C by dihedral angles of 79.7 (2) and 62.9 (2)°, respectively.

Supra­molecular features

In the crystal, weak C—HOxqn⋯OEthx and C—HPh­yl⋯OCarbx (Oxqn = oxoquinolin, Ethx = eth­oxy, Phyl = phenyl and Carbx = carboxyl­ate) hydrogen bonds (Table 1) link the mol­ecules into a three-dimensional network structure (Fig. 2). A π–π contact between the constituent rings, i.e.A (N1/C1–C4/C9) and B (C4–C9), of the oxo­quinoline unit, with Cg1⋯Cg2 = 3.675 (1) Å [symmetry code: (i) −x + 1, −y + 1, −z + 1; Cg1 and Cg2 are the centroids of rings A and B], may further stabilize the structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for crystal packing are from H⋯H (53.9%), H⋯O/O⋯H (28.5%) and H⋯C/C⋯H (11.8%) inter­actions. Weak inter­molecular hydrogen-bond inter­actions and van der Waals inter­actions are the dominant inter­actions in the crystal packing.

Hirshfeld surface analysis

In order to visualize the inter­molecular inter­actions in the title com­pound, a Hirshfeld surface (HS) analysis (Hirshfeld, 1977; Spackman & Jayatilaka, 2009) was carried out by using CrystalExplorer17.5 (Turner et al., 2017). In the HS plotted over dnorm (Fig. 3), the white surface indicates contacts with distances equal to the sum of the van der Waals radii, and the red and blue colours indicate distances shorter (in close contact) or longer (distinct contact) than the van der Waals radii, respectively (Venkatesan et al., 2016). The bright-red spots appearing near O2 and H atoms H7 and H22 indicate their roles as the respective donors and/or acceptors; they also appear as blue and red regions corresponding to positive and negative potentials on the HS mapped over the electrostatic potential (Spackman et al., 2008; Jayatilaka et al., 2005), as shown in Fig. 4. The blue regions indicate a positive electrostatic potential (hydrogen-bond donors), while the red regions indicate a negative electrostatic potential (hydrogen-bond acceptors). The shape-index of the HS is a tool to visualize the π–π stacking by the presence of adjacent red and blue triangles; if there are no adjacent red and/or blue triangles, then there are no π–π inter­actions. Fig. 5 clearly suggests that there are π–π inter­actions in (I). The overall two-dimensional fingerprint plot (Fig. 6a) and those delineated into H⋯H, H⋯O/O⋯H, H⋯C/C⋯H, C⋯C and O⋯C/C⋯O contacts (McKinnon et al., 2007) are illustrated in Figs. 6(b)–(f), respectively, together with their relative contributions to the Hirshfeld surface. The most important inter­action is H⋯H, contributing 53.9% to the overall crystal packing, which is reflected in Fig. 6(b) as widely scattered points of high density due to the large hydrogen content of the mol­ecule, with the tip at de = di = 1.05 Å, due to the short inter­atomic H⋯H contacts. The pair of characteristic wings resulting in the fingerprint plot delineated into H⋯O/O⋯H contacts (Fig. 6c) has a 28.5% contribution to the HS and is viewed as a pair of spikes with the tips at de + di = 2.30 Å. In the absence of weak C—H⋯π inter­actions, the pair of characteristic wings resulting in the fingerprint plot delineated into H⋯C/C⋯H contacts (Fig. 6d), with a 11.8% contribution to the HS and are viewed as a pair of spikes with the tip at de + di = 2.83 Å. The C⋯C contacts (Fig. 6e) have an arrow-shaped distribution of points with the tip at de = di = 1.81 Å. Finally, the pair of the scattered points of wings from the fingerprint plot are delineated into O⋯C/C⋯O (Fig. 6f) contacts, with a 1.1% contribution to the HS, and has a nearly symmetrical distribution of points with the edges at de + di = 3.15 Å.

The Hirshfeld surface analysis confirms the importance of weak H-atom contacts in establishing the packing structure. The large number of H⋯H, H⋯O/O⋯H and H⋯C/C⋯H inter­actions suggest that van der Waals inter­actions and weak hydrogen-bond inter­molecular inter­actions play major roles in the crystal packing (Hathwar et al., 2015).

DFT calculations

The geometry optimized structure of the title com­pound in the gas phase was generated theoretically via density functional theory (DFT) com­putational calculations using a standard B3LYP functional and a 6-311G(d,p) basis set (Becke, 1993), as implemented in GAUSSIAN09 (Frisch et al., 2009). The theoretical and experimental results were in good agreement (Table 2). A DFT mol­ecular orbital calculation indicated that the highest-occupied mol­ecular orbital (HOMO), acting as an electron donor, and the lowest-unoccupied mol­ecular orbital (LUMO), acting as an electron acceptor, are very important parameters for quantum chemistry. When the energy gap is small, the mol­ecule is highly polarizable and has high chemical reactivity. Therefore, these DFT calculations provide important information on the reactivity and site selectivity of the mol­ecular framework. EHOMO and ELUMO clarify the inevitable charge exchange collaboration inside the studied material, as well as electronegativity (χ), hardness (η), potential (μ), electrophilicity (ω) and softness (σ), which are listed in Table 3. The significance of η and σ is to evaluate both reactivity and stability. The electron transition from a HOMO to a LUMO energy level is shown in Fig. 8. The HOMO and LUMO are localized in the plane extending from the whole ethyl 2-{4-[(2-eth­oxy-2-oxoeth­yl)(phen­yl)carbamo­yl]-2-oxo-1,2-di­hydro­quinolin-1-yl}acetate ring. The energy band gap [ΔE = ELUMOEHOMO] of the mol­ecule was about 4.2091 eV, and the frontier mol­ecular orbital (FMO) energies, i.e. EHOMO and ELUMO, were −6.1141 and −1.9050 eV, respectively.

Database survey

A non-a­lkylated analogue, namely quinoline and its derivatives, has been reported (Filali Baba et al., 2016b, 2017; Bouzian et al., 2019a), as well as three similar structures (see Castañeda et al., 2014; Kafka et al., 2012; Bouzian et al., 2018, 2019a; Divya Bharathi et al., 2015).

Synthesis and crystallization

To a solution of 2-oxo-N-phenyl-1,2-di­hydro­quinoline-4-carboxamide (1.89 mmol) in di­methyl­formamide (DMF, 10 ml) were added ethyl bromo­acetate (4.16 mmol), K2CO3 (5.67 mmol) and tetra­butyl­ammonium bromide (TBAB, 0.23 mmol). The reaction mixture was stirred at room temperature for 6 h. After removal of the salts by filtration, the DMF was evaporated under reduced pressure and the resulting residue was dissolved in di­chloro­methane. The organic phase was dried with Na2SO4 and then concentrated under reduced pressure. The pure com­pound was obtained by column chromatography using as eluate hexa­ne/ethyl acetate (3:1 v/v). The isolated solid was recrystallized from hexa­ne–diethyl acetate (1:1 v/v) to afford colourless crystals (yield 75%; m.p. 427 K).

Refinement

The experimental details, including the crystal data, data collection and refinement, are summarized in Table 4. H atoms were positioned geometrically, with C—H = 0.93, 0.97 and 0.96 Å for aromatic CH, CH2 and CH3 H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = kUeq(C), where k = 1.5 for CH3 H atoms and k = 1.2 for other H atoms. The terminal ethyl groups are disordered with an occupancy ratio of 0.821 (8):0.179 (8) for C12 and C13, and 0.651 (18):0.349 (18) for C17 and C18.

Abstract

The title com­pound, C24H24N2O6, consists of ethyl 2-(1,2,3,4-tetra­hydro-2-oxo­quinolin-1-yl)acetate and 4-[(2-eth­oxy-2-oxoeth­yl)(phen­yl)carbomoyl] units, where the oxo­quinoline unit is almost planar and the acetate substituent is nearly perpendicular to its mean plane. In the crystal, C—HOxqn⋯OEthx and C—HPh­yl⋯OCarbx (Oxqn = oxoquinolin, Ethx = eth­oxy, Phyl = phenyl and Carbx = carboxyl­ate) weak hydrogen bonds link the mol­ecules into a three-dimensional network sturucture. A π–π inter­action between the constituent rings of the oxo­quinoline unit, with a centroid–centroid distance of 3.675 (1) Å may further stabilize the structure. Both terminal ethyl groups are disordered over two sets of sites. The ratios of the refined occupanies are 0.821 (8):0.179 (8) and 0.651 (18):0.349 (18). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (53.9%), H⋯O/O⋯H (28.5%) and H⋯C/C⋯H (11.8%) inter­actions. Weak inter­molecular hydrogen-bond inter­actions and van der Waals inter­actions are the dominant inter­actions in the crystal packing. Density functional theory (DFT) geometric optimized structures at the B3LYP/6-311G(d,p) level are com­pared with the experimentally determined mol­ecular structure in the solid state. The HOMO–LUMO mol­ecular orbital behaviour was elucidated to determine the energy gap.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
