Crystal structure of racemic [(1R,2S,3R,4S,6S)-2,6-bis-(furan-2-yl)-4-hy-droxy-4-(thio-phen-2-yl)cyclo-hexane-1,3-di-yl]bis-(thio-phen-2-yl-methanone).

In the title compound, C28H22O5S3, the central cyclo-hexane ring adopts a chair conformation. The atoms of the furan ring attached to the 6-position of the central cyclo-hexane ring are disordered over two sets of sites with occupancies of 0.832 (5) and 0.168 (5). The hy-droxy group is disordered over two positions (at the 4- and 6-positions of the cyclo-hexane ring) in the ratio 0.832 (5):0.168 (5). In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming layers parallel to (100).

Chemical context

Domino or cascade reactions have many applications in organic chemistry (Tietze et al., 2006 ▸). They are used for the synthesis of complex mol­ecules that have polysubstituted and multiple stereocenters in a single step (Pellissier, 2012 ▸, 2013 ▸). Penta­substituted cyclo­hexa­nol derivatives can be synthesized from aromatic aldehydes and ketones via domino reaction (Luo & Shan, 2006 ▸; Gezegen & Ceylan, 2015 ▸). In this paper we report the synthesis of [(1R,2S,3R,4S,6S)-2,6-bis­(furan-2-yl)-4-hy­droxy-4-(thio­phen-2-yl)cyclo­hexane-1,3-di­yl]bis­(thio­phen-2-yl­methanone) in a high yield starting from 2-acetyl­thio­phene and furfural. The resulting product is a racemate crystallizing in a centrosymmetric space group.

Structural commentary

In the title compound, Fig. 1 ▸, the central cyclo­hexane ring adopts a chair conformation [the puckering parameters are Q T = 0.586 (3) Å, θ = 0.0 (3)° and φ = 169 (17)°]. The mean plane of this ring makes dihedral angles of 80.42 (14), 59.57 (17), 85.65 (17), 66.82 (19), 84.88 (18) and 83.1 (8)°, respectively, with the five associated five-membered rings (S1/C8–C11, S2/C16–C19, S3/C21–C24, O2A/C12A–C15A, O5/C25–C28 and O2B/C12B–C15B).

Supra­molecular features

The mol­ecular conformation is stabilized by a weak intra­molecular O—H⋯O inter­action (Table 1 ▸). C—H⋯O hydrogen bonds together with C—H⋯π contacts, Table 1 ▸, form layers of mol­ecules when viewed along both the a- and b-axis directions, Figs. and 3. Short S3⋯S3ii contacts [symmetry code: (ii) −x + 1, −y, −z + 1] at 3.5210 (12) Å may also contribute to the crystal packing (Figs. 2 ▸ and 3 ▸).

Semi-empirical quantum mechanical calculations

According to the results of theoretical calculations carried out using the semi-empirical quantum-mechanical CNDO/2 (Complete Neglect of Differential Overlap) method (Pople & Beveridge, 1970 ▸), the spatial view of the single mol­ecule, with atomic labels, calculated as a closed-shell in a vacuum is shown in Fig. 4 ▸. The net charges on atoms O1, O2, O3, O4, O5, S1, S2 and S3 are −0.330, −0.113, −0.279, −0.341, −0.158, −0.014, −0.055 and −0.021 e−, respectively. This is useful as prediction of the electron-rich and electron-poor sites of a molecule provides a rough estimate of chemical and physical properties of the molecule. The dipole moment of the title mol­ecule is 3.626 Debye. The HOMO and LUMO energy levels are −10.31 and 1.72 eV, respectively. The values of the HOMO and LUMO energy levels determine the way in which the molecule interacts with other species and help to characterize the chemical reactivity and kinetics of the molecule.

Figure 4

Spatial view of the mol­ecule of the title compound calculated using the CNDO method.

The geometrical parameter values obtained by the X-ray structure determination of the title compound are consistent with those calculated by the CNDO/2 method within the error limits (Table 2 ▸). Small differences between the theoretical and experimental results may result from the calculations assuming the mol­ecule is in a vacuum.

Synthesis and crystallization

[(1R,2S,3R,4S,6S)-2,6-bis­(furan-2-yl)-4-hy­droxy-4-(thio­phen-2-yl)cyclo­hexane-1,3-di­yl]bis­(thio­phen-2-yl­methanone) was synthesized according to a literature method (Gezegen & Ceylan, 2015 ▸) in 87% yield. Colourless prisms were recrystallized from ethanol solution, m.p = 524–526 K.

Refinement details

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. Atoms O2,C12-C15 atoms of the furan ring bound to the C1 atom of the central cyclo­hexane ring are disordered over two sets of sites with an occupancy ratio 0.832 (5):0.168 (5). The O3 hy­droxy group is disordered over two positions (on the C1 and C3 atoms of the cyclo­hexane ring) in the same ratio. The positionally disordered H atoms (H1A on C1 and H1B on C3) were found from a difference Fourier map and their positions were constrained to the expected geometries [C—H = 0.95±0.02 Å] with a fixed U value of 0.05 Å2. All other H atoms were placed in calculated positions (C—H = 0.93–0.98, O—H = 0.82 Å) and refined using a riding model with U iso(H) = 1.2U eq(carrier).

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 esds 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 > 2sigma(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.
