Syntheses and structures of two benzoyl amides: 2-chloro-4-eth­oxy-3,5-dimeth­oxy-N-(3-oxo­cyclo­hex-1-en-1-yl)benzamide and 2-chloro-N-(5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl)-4-eth­oxy-3,5-di­meth­oxy­benzamide

The crystal structures of two benzoyl amides: 2-chloro-4-eth­oxy-3,5-dimeth­oxy-N-(3-oxo­cyclo­hex-1-en-1-yl)benzamide and 2-chloro-N-(5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl)-4-eth­oxy-3,5-di­meth­oxy­benzamide have been determined.

Abstract

The first title benzoyl amide, C₁₇H₂₀ClNO₅ (3a), crystallizes in the monoclinic space group P2₁/c with Z = 4 and the second, C₁₉H₂₄ClNO₅ (3b), also crystallizes in P2₁/c with Z = 8 (Z′ = 2), thus there are two independent mol­ecules in the asymmetric unit. In 3a, the phenyl ring makes a dihedral angle of 50.8 (3)° with the amide moiety with the C=O group on the same side of the mol­ecule as the C—Cl group. One meth­oxy group is almost in the plane of the benzene ring, while the eth­oxy and other meth­oxy substituent are arranged on opposite sides of the ring with the eth­oxy group occupying the same side of the ring as the C=O group in the amide moiety. For one of the two mol­ecules in 3b, both the amide and 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moieties are disordered over two sets of sites with occupancies of 0.551 (2)/0.449 (2) with the major difference between the two conformers being due to the conformation adopted by the cyclo­hex-2-en-1-one ring. The three mol­ecules in 3b (i.e., the undisordered mol­ecule and the two disorder components) differ in the arrangement of the subsituents on the phenyl ring and the conformation adopted by their 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moieties. In the crystal of 3a, N—H⋯O hydrogen bonds link the mol­ecules into a zigzag chain propagating in the [001] direction. For 3b a combination of C—H⋯O and N—H⋯O inter­molecular inter­actions link the mol­ecules into a zigzag ribbon propagating in the [001] direction.

Chemical context  

Enamino­nes are compounds in which a nitro­gen atom is conjugated through a carbon–carbon double bond to an ester (vinyl­ogous urethane) or a ketone (vinyl­ogous amide) functional group (see Scheme). Enamino­nes may be viewed as amides into which a vinyl fragment has been inter­polated. Designations often used, such as enamino ketone or β-amino-α, β-unsaturated ketone, are misleading in that the compounds rarely exhibit the physical properties normally associated with ketones. Enamino­nes, compounds possessing the structural unit NH₂—C=C—C=O, are versatile synthetic inter­mediates that combine the ambient nucleophilicity of enamines with the ambient electrophilicity of enones (Greenhill, 1976 ▸; Lue & Greenhill, 1996 ▸).

β-Enamino­nes may be used in the synthesis of many bioactive mol­ecules with a heterocyclic unit. Enamino­nes as inter­mediates are responsible for a wide range of therapeutic agents from both natural and synthetic sources including taxol, anti­convulsants, anti-inflammatories, and duocarmycin, and consequently have been the subject of numerous structural bioactivity investigations in recent times (Misra et al., 2008 ▸; Greenhill, 1977 ▸; Boger et al., 1989 ▸; Eddington et al., 2003 ▸; Stoltz et al., 2016 ▸; Jerach & Elassar, 2015 ▸; Kalita et al., 2017 ▸). In spite of the breadth of research related to the biological properties of enamino­nes, recent research also indicates that enamino­nes, particularly the cyclic 3-(phenyl­amino)-2-cyclo­hexen-1-one (PACO), contain spectroscopic signatures of intra­molecular charge transfer (ICT), making cyclic enamino­nes ideal components for mol­ecules that mimic natural photosynthetic energy and electron transfer (Lue & Greenhill, 1996 ▸). A later study conducted in 2009 concluded that PACO has a low lying strongly polar singlet excited state with significant intra­molecular charge transfer (Misra et al., 2009 ▸).

We herein describe the synthesis and structural characterization of the title benzoyl amides 2-chloro-4-eth­oxy-3,5-dimeth­oxy-N-3-oxo­cyclo­hex-1-en-1-yl)benzamide, 3a and 2-chloro-N-(5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl)-4-eth­oxy-3,5-di­meth­oxy­benzamide, 3b developed in connection with an ongoing research inter­est.

Structural commentary  

In view of the bioactivity of enamino­nes, the conformation adopted by a mol­ecule is crucial to its activity. Thus an analysis of this for both mol­ecules is appropriate. The benzoyl amide, C₁₇H₂₀ClNO₅ (3a), crystallizes in the monoclinic space group P2₁/c with Z = 4. The compound is the result of the condensation of the enaminone 1a with the acid chloride 2. In the case of 3a (Fig. 1 ▸), the central phenyl ring makes a dihedral angle of 50.8 (3)° with the amide moiety; with the C=O group on the same side of the mol­ecule as the C—Cl group; in the 3-oxo­cyclo­hex-1-en-1-yl group the C=O moiety is on the same side with respect to the phenyl ring [the pseudo torsion angle for O4—C11⋯C14—O5 = 21.8 (1)°]. One of the meth­oxy groups (O3—C10) attached to the C1–C6 benzene ring is close to the plane of the ring [torsion angle between the ring and C5—O3—C10 = 17.72 (2)°], while the eth­oxy and the other meth­oxy substituent are arranged on opposite sides of the ring with the eth­oxy group occupying the same side of the ring as the C=O group in the amide moiety [C8—O2⋯C11—O4 = −44.0 (1) and C7—O1⋯C11—O4 = 123.6 (1)°]. The extended conformation of the eth­oxy group with respect to the ring is shown by a torsion angle of −170.8 (1)° for C4—O2—C8—C9.

The benzoyl amide, C₁₉H₂₄ClNO₅ (3b), crystallizes in the monoclinic space group P2₁/c with Z = 8 (Z′ = 2), thus there are two independent mol­ecules in the asymmetric unit. The compound is the result of the condensation of the enaminone 1b with the acid chloride 2. For one of the two mol­ecules, both the amide and 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moieties are disordered over two inequivalent conformations with occupancies of 0.551 (2)/0.449 (2). The major difference between the two conformers is due to the conformation adopted by the cyclo­hex-2-en-1-one ring (vide infra).

The conformations of both independent mol­ecules will be discussed separately and then comparisons will be made between the conformation of 3a and the two mol­ecules of 3b in which, due to disorder, one has adopted two different conformations. For simplicity, these will be called 3ba, 3bb and 3bc (where 3bb and 3bc are the major and minor components, respectively, of the disordered mol­ecule). For 3ba (Fig. 2 ▸) the central phenyl ring makes a dihedral angle of 54.5 (3)° with the amide moiety with the C=O group on the opposite side of the mol­ecule as the C—Cl group in contrast to the situation in 3a (this is illustrated by the respective C2—C1⋯C11—O4 torsion angles of 47.2 (2) and −129.5 (2) for 3a and 3ba, respectively). In both the amide moiety and the 3-oxo­cyclo­hex-1-en-1-yl group, the C=O moiety is on the same side [the torsion angle for O4A—C11A⋯C14A—O5A = −17.5 (1)°]. For the substituents on the phenyl ring, one meth­oxy group is almost coplanar with the ring [torsion angle between the ring and C5A—O3A—C10A = 3.5 (2)°] while in contrast to the situation in 3a, both the other meth­oxy and eth­oxy substituents are on the same side of the ring [torsion angles for C7A—O1A⋯C11A—O4A and C8A—O2A⋯C11A—O4A = −32.4 (2) and −6.4 (2)°, respectively]. The conformation of the eth­oxy substituent is different than that in 3a in that it has not adopted a fully extended aspect [C4A—O2A—C8A—C9A = −148.77 (16)].

Figure 2.

As indicated above, 3bb and 3bc are the major and minor components of the disordered 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moieties with occupancies of 0.551 (2)/0.449 (2) (Fig. 3 ▸). The difference in the conformation of this group can be seen by the torsion angles for the C12—C17—C16—C15 grouping in 3a, 3ba, 3bb and 3bc of −48.67 (17), 50.11 (15), −51.7 (7) and 53.9 (10)°, respectively. From this it can be seen that for this moiety, 3a and 3bb have a similar conformation and 3ba and 3bc also have a similar conformation. For 3bb, the central phenyl ring makes a dihedral angle of 55.8 (9)° with the amide moiety with the C=O group on the opposite side of the mol­ecule as the C—Cl group [torsion angle for C2B—C1B⋯C11B—O4B = −122.81 (13)]. In both the amide moiety and the 3-oxo­cyclo­hex-1-en-1-yl group, the C=O moiety is on the same side [O4B—C11B⋯C14B—O5B = 13.7 (2)°]. For the substituents on the phenyl ring, one meth­oxy group is almost coplanar with the ring [torsion angle between ring and meth­oxy group of 2.3 (2)] while the other meth­oxy group and eth­oxy groups are on opposite sides of the ring [torsion angles for C7B—O1B⋯C11B—O4B and C8B—O2B⋯C11B—O4B = 165.4 (2) and −46.6 (2)°, respectively]. The conformation of the eth­oxy substituent is different than that in 3a in that it has not adopted an extended aspect [C4B—O2B—C8B—C9B = 67.92 (16)°].

Both 3bb and 3bc retain the same (undisordered) phenyl moiety and the only differences are in the conformation of the 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moiety, thus in discussing this mol­ecule we only have to consider the amide moiety and the 3-oxo­cyclo­hex-1-en-1-yl group where the C=O moiety is on the same side [O4B—C11B⋯C14C—O5C = −9.1 (2)°].

Supra­molecular features  

For 3a, N—H⋯O hydrogen bonds (Table 1 ▸) link the mol­ecules into a zigzag chain propagating in the [001] direction as shown in Fig. 4 ▸.

Database survey  

A survey of the Cambridge Structural Database for similar compounds did not provide any hits. Even if the mol­ecules are broken up into two components, one based on the tris­ubstituted phenyl ring and the other on the cyclo­hexene ring no hits for the former and only one hit for the latter fragment is obtained [Cambridge Structural Database refcode MOLPUA (Meng et al., 2014 ▸)]. Even in this structure the only similar chromophore is the cyclo­hex-2-ene-1-one fragment, but with the double bond in a different position in the ring. For similar structures to this fragment but containing a cyclo­hexane ring there are DOSDOE, DOSBUK (Romney et al., 2014 ▸) and KAVDAP (Alford et al., 2016 ▸).

Synthesis and crystallization  

The methodology involves N-deprotonation of the commercially available enamino­nes 1a,b with sodium hydride followed by benzoyl­ation of 2 to give the title benzoyl amides 3a,b in 54% and 51% yield, respectively, from a method previously reported (see Scheme 1; Anderson et al., 2004 ▸). Benzoyl chloride 2 was prepared via chlorination of commercially available 4 under previously reported conditions (Zheng et al., 2011 ▸).

Preparation of 2-chloro-4-eth­oxy-3,5-di­meth­oxy­benzoyl chloride (2)

A solution of commercially available 2-chloro-4-eth­oxy-3,5-di­meth­oxy­benzoic acid, 4 (2.07 g, 7.7 mmol), and a catalytic amount of DMF in thionyl chloride (5 ml) was stirred at 353–363 K for 3 h to give the crude acid chloride 2. The mixture was concentrated under reduced pressure and used without any further purification. ¹H NMR: (400 MHz, DMSO): δ 1.40–1.45 (3H, t, CH₃), δ 3.03 (3H, s, CH₃), δ 3.19 (3H, s, CH₃), 4.21–4.28 (2H, q, CH₂), 7.48 (H, s, aromatic H).

Preparation of 2-chloro-4-eth­oxy-3,5-dimeth­oxy- N -(3-oxo­cyclo­hex-1-en-1-yl)benzamide (3a)

The enaminone, 1a (0.799 g, 7.2 mmol), under an inert atmosphere, was stirred in a solution of NaH (0.391 g, 17.2 mmol) in dry THF (40 ml) maintaining the temperature below 293 K. The reaction was refluxed for 20 minutes, cooled to room temperature and stirred on an ice-bath for 5 minutes before a solution of benzoyl chloride 2 (2.09 g, 7.5 mmol) in dry THF (10 ml) was added dropwise over 5 minutes. After stirring at room temperature for a further 10 minutes, the mixture was quenched with concentrated hydro­chloric acid (∼5 ml) and diluted with di­chloro­methane (25 ml). The mixture was transferred to a separatory funnel and washed successively with water (25 ml), 10% NaHCO₃ and with water again. The organic layer was dried over sodium sulfate and concentrated in vacuo. The crude residue was purified by column chromatography (silica gel, EtOAc:hexa­nes = 5:5) to give compound 3a (1.37 g, 54%) as a faint yellow solid. (m.p. = 417–418 K) R _f (EtOAc:hexa­nes 7:3) ¹H NMR: (400 MHz, DMSO): 1.01 (6H, s, 2 × CH₃), δ 1.27–1.32 (3H, t, CH₃), 2.16 (2H, m, CH₂), 2.43 (2H, t, CH₂), 3.83 (6H, s, 2 × CH₃), δ4.01–4.07 (2H, quart, CH₂), δ 6.70 (H, s, CH), 7.04 (H, s, aromatic H), 10.25 (H, s, NH) ppm; ¹³C NMR (DMSO) δ 198.60, 165.69, 154.02, 152.27, 149.54, 142.88, 131.24, 115.82, 110.15, 107.81, 68.80, 60.83, 56.32, 49.96, 40.85, 32.13, 27.73, 15.35 ppm.

Preparation of 2-chloro- N -(5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl)-4-eth­oxy-3,5-δi­meth­oxy­benzamide (3b)

The same synthesis and purification method as for 3a was used to prepare 3b except that 1.00 g (7.2 mmol) of the enaminone 1b replaced 1a: this gave compound 3b (1.40 g, 51%) as a light white solid. (m.p. = 331–332 K) R _f (EtOAc:hexa­nes 7:3) ¹H NMR: (400 MHz, DMSO): δ 1.27–1.32 (3H, t, CH₃), δ 1.8.7–1.95 (2H, quintet, CH₂), 2.22–2.29 (2H, t, CH₂), 3.32 (6, s, 2 × CH₃, slight long-range coupling noticed), δ 4.00–4.06 (2H, quart, CH₂), δ 6.71 (H, s, CH), 7.04 (H, s, aromatic H), 10.30 (H, s, NH) ppm; ¹³C NMR (DMSO) δ 198.62, 165.56, 156.14, 152.27, 149.55, 142.85, 131.27, 115.77, 110.76, 107.76, 68.80, 60.83, 56.32, 49.96, 40.85, 32.13, 27.73, 21.11, 15.35 ppm.

For both 3a and 3b crystals were grown from a 2:1 ethanol:water mixed solvent system.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. The N-bound H atoms were located in difference maps and their positions were freely refined. A riding model was used for the H atoms attached to C with C—H distances ranging from 0.95 to 0.99 Å and U _iso(H) = 1.2U _eq(C) [1.5U _eq(CH₃)]. For 3b there are two independent mol­ecules in the asymmetric unit, in one of which the 5,5-dimethyl-3-oxo­cyclo­hex-1-en-1-yl moiety is disordered and was treated with similar metrical parameters with refined occupancies of 0.551 (2)/0.449 (2).

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.

2-Chloro-N-(5,5-dimethyl-3-oxocyclohex-1-en-1-yl)-4-ethoxy-3,5-dimethoxybenzamide (3b) . 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.

Refinement. Compound #6
