Crystal structures of three indole derivatives: 3-ethnyl-2-methyl-1-phenyl­sulfonyl-1H-indole, 4-phenyl­sulfonyl-3H,4H-cyclo­penta­[b]indol-1(2H)-one and 1-{2-[(E)-2-(5-chloro-2-nitro­phen­yl)ethen­yl]-1-phenyl­sulfonyl-1H-indol-3-yl}ethan-1-one chloro­form monosolvate

The title compounds, (I), (II) and (III), are indole derivatives. Compounds (I) and (II) present two independent moieties in the asymmetric unit, and their packing is led by C—H⋯O hydrogen bonds and C—H⋯π inter­actions. In compound (III), the C—H⋯O hydrogen bonds form (22) inversion dimers.

Abstract

The title compounds, C₁₇H₁₃NO₂S, (I), C₁₇H₁₃NO₃S, (II), and C₂₄H₁₇ClN₂O₅S·CHCl₃, (III), are indole derivatives. Compounds (I) and (II) crystalize with two independent mol­ecules in the asymmetric unit. The indole ring systems in all three structures deviate only slightly from planarity, with dihedral angles between the planes of the pyrrole and benzene rings spanning the tight range 0.20 (9)–1.65 (9)°. These indole ring systems, in turn, are almost orthogonal to the phenyl­sulfonyl rings [range of dihedral angles between mean planes = 77.21 (8)–89.26 (8)°]. In the three compounds, the mol­ecular structure is stabilized by intra­molecular C—H⋯O hydrogen bonds, generating S(6) ring motifs with the sulfone O atom. In compounds (I) and (II), the two independent mol­ecules are linked by C—H⋯O hydrogen bonds and C—H⋯π inter­actions, while in compound (III), the mol­ecules are linked by C—H⋯O hydrogen bonds, generating R ₂ ²(22) inversion dimers.

Chemical context  

Indole is an aromatic heterocyclic group, the parent of a large number of important compounds in nature with significant biological activity (Kaushik et al., 2013 ▸). The indole ring system occurs in plants (Nigovic et al., 2000 ▸); for example, indole-3-acetic acid is a naturally occuring auxin that controls several plant growth activities (Moore, 1989 ▸; Fargasova, 1994 ▸). Indole derivatives exhibit anti­bacterial, anti­fungal (Singh et al., 2000 ▸), anti­tumor (Andreani et al., 2001 ▸), anti­hepatitis B virus (Chai et al., 2006 ▸) and anti-inflammatory (Rodriguez et al., 1985 ▸) activities. They are also used as bioactive drugs (Stevenson et al., 2000 ▸) and have also been proven to display high aldose reductase inhibitory (Rajeswaran et al., 1999 ▸) and anti­microbial activities (Amal Raj et al., 2003 ▸). Indole derivatives are also found to possess hypertensive, muscle relaxant (Hendi & Basangoudar, 1981 ▸) and anti­viral (Kolocouris et al., 1994 ▸) activities. Some of the indole alkaloids extracted from plants possess inter­esting cytotoxic and anti­parasitic properties (Quetin-Leclercq, 1994 ▸). Against this background, the X-ray structure determination of 3-ethnyl-2-methyl-1-phenyl­sulfonyl-1H-indole, (I), 4-phenyl­sulfonyl-3H,4H-cyclo­penta­[b]indol-1(2H)-one, (II), and 1-{2-[(E)-2-(5-chloro-2-nitro­phen­yl)ethen­yl]-1-phenyl­sulfonyl-1H-indol-3-yl}ethan-1-one chloro­form monosolvate, (III), has been carried out to study their structural aspects and the results are presented here.

Structural commentary  

The mol­ecular structures of title compounds (I), (II) and (III) are shown in Figs. 1 ▸, 2 ▸ and 3 ▸, respectively. Compounds (I) and (II) comprise two crystallographically independent mol­ecules (A and B) in the asymmetric unit. The corresponding bond lengths and bond angles of mol­ecules A and B [in compounds (I) and (II)] agree well with each other, as illustrated in Figs. 4 ▸ and 5 ▸. The indole ring systems depart slightly from planarity, the dihedral angles formed between the pyrrole rings and benzene rings being 1.65 (9) and 0.97 (10) [mol­ecules A and B of compound (I)], 0.20 (9) and 0.86 (9) [mol­ecules A and B of compound (II)], and 1.34 (14)° [compound (III)].

The indole ring systems are almost orthogonal to the phenyl­sulfonyl rings [dihedral angles = 77.21 (8) and 89.26 (8)° in (I), 78.98 (7) and 80.48 (8)° in (II), and 83.17 (13)° in (III)]. In the case of (II), the indole ring systems are nearly coplanar with the cyclo­penta­none rings [dihedral angles: = 0.58 (9) and 1.52 (8)°].

In all three compounds, as a result of the electron-withdrawing character of the phenyl­sulfonyl group, the N—Csp ² bond lengths are longer than the mean value of 1.355 (14)Å for the N—C bond length (Allen et al., 1987 ▸). Atom S1 has a distorted tetra­hedral configuration. The widening of the angle O1=S1=O2 and the narrowing of the angle N1—S1—C9 from ideal tetra­hedral values are attributed to the Thorpe–Ingold effect (Bassindale, 1984 ▸). The widening of the angles may be due to the repulsive inter­action between the two short S=O bonds.

In all three compounds, the expansion of the ispo angles at atoms C1, C3 and C4, and the contraction of the apical angles at atoms C2, C5 and C6 are caused by fusion of the smaller pyrrole ring with the six-membered benzene ring and the strain is taken up by the angular distortion rather than by bond-length distortion (Allen, 1981 ▸).

The sums of the bond angles around atoms N1 are 351.55 and 356.16° in (I), 359.86 and 359.29° in (II), and 352.79° in (III), indicating sp ² hybridization. In all three compounds, the mol­ecular structure is stabilized by intra­molecular C—H⋯O hydrogen bonds which generate S(6) ring motifs with the sulfone O atom (Tables 1 ▸, 2 ▸ and 3 ▸). In addition to these, in compound (III), the mol­ecular structure is characterized by intra­molecular C25—Cl3⋯O2 halogen bonding (XB), between the solvent Cl atom (Cl3) and sulfone-group O atom (O2) [Cl3⋯O2 = 3.036 (2) Å and with a bond angle of 164.48 (14)°].

Supra­molecular features  

In the crystal packing of compound (I), the mol­ecules are linked via inter­molecular C16B—H16B⋯O2A(−x + 1, y + , −z + 1) hydrogen bonds running parallel to the [101] direction. The crystal packing is further stabilized by inter­molecular C10A—H10A⋯Cg1, C11A—H11A⋯Cg2 and C16A—H16A⋯Cg3 inter­actions, with separations of 3.727 (2), 3.546 (2) and 3.699 (3) Å at (−x + 2, y − , −z + 1) and (−x + 1, y + , −z), respectively.

Synthesis and crystallization  

Compound (I)  

A solution of [(3-acetyl-1-phenyl­sulfanyl-1H-indol-2-yl)meth­yl]tri­phenyl­phospho­nium ylide (0.5 g, 9 mmol) in dry toluene (20 ml) was refluxed for 12 h under an N₂ atmosphere. After consumption of the starting material [monitered by thin-layer chromatography (TLC)], removal of the solvent in vacuo followed by column chromatographic purification (silica gel, EtOAc–hexane 1:9 v/v) gave (I) (yield 1.30 g, 29%) as a colourless solid. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of compound (I) in ethyl acetate at room temperature (m.p. 383–385 K).

Compound (II)  

Reaction of 2-bromo­methyl-1-(1-phenyl­sulfonyl-1H-indol-3-yl)ethan-1-one (0.2 g, 5 mmol) with K₂CO₃ (0.35 g, 5 mmol) in aceto­nitrile was carried out under reflux for 8 h under an N₂ atmosphere. After the consumption of the starting material (monitered by TLC), the reaction mass was poured over crushed ice and extracted with di­chloro­methane (2 × 15 ml). The organic layers were combined and washed with brine solution (2 × 20 ml) and dried (Na₂SO₄). The crude product was purified by column chromatography (silica gel, EtOAc–hexane 1:4 v/v) to give (II) (yield 1.40 g, 88%) as a white solid. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of compound (II) in ethyl acetate at room temperature (m.p. 475–481 K).

Compound (III)  

A solution of [(3-acetyl-1-phenyl­sufanyl-1H-indol-2-yl)meth­yl]tri­phenyl­phosphonium ylide (3 g, 5.23 mmol) and 5-chloro­nitro­benzaldehyde (1.06 g, 5.75 mmol) in dry chloro­form (50 ml) was refluxed for 10 h under an N₂ atmosphere. Removal of the solvent in vacuo followed by titration of the crude product with methonal (10 ml), gave (III) (yield 2.29 g, 91%) as a yellow solid. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of compound (III) in chloro­form at room temperature (m.p. 439–441 K).

Refinement  

Crystal data, data collection and structure refinement details for compounds (I), (II) and (III) are summarized in Table 4 ▸. The positions of the H atoms were localized from the difference electron-density maps and their distances were geometrically constrained. H atoms bound to the C atoms were treated as riding atoms, with C—H = 0.93, 0.96, 0.97 and 0.98 Å for aryl, methyl, methyl­ene and methine H atoms, respectively, with U _iso(H) = 1.5U _eq(methyl C) and 1.2U _eq(nonmethyl C). The rotation angles for methyl groups were optimized by least squares.

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.

(II) 4-Phenylsulfonyl-3H,4H-cyclopenta[b]indol-1(2H)-one . Special details

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.

(III) 1-{2-[(E)-2-(5-Chloro-2-nitrophenyl)ethenyl]-1-phenylsulfonyl-1H-indol-3-yl}ethan-1-one chloroform monosolvate . Special details

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.
