In the title compound, C22H19NO5S·C2D6OS, the central six-membered ring has a slightly distorted boat conformation, while the fused pyrrolidine ring adopts an These conformations are stabilized by O—H⋯O hydrogen bonds between the main compound and solvent molecules. In addition, intramolecular C—H⋯O hydrogen bonds in the main molecule form two S(6) rings. Molecules are connected by pairs of intermolecular C—H⋯O hydrogen bonds, forming dimers with a R22(8) motif. These dimers form a three-dimensional network through O—H⋯O, O—H⋯S and C—H⋯O hydrogen bonds with each other directly and through solvent molecules. In addition, weak π–π stacking interactions [centroid-to-centroid distances = 3.9937 (10) and 3.9936 (10) Å, slippages of 2.034 and 1.681 Å] are observed. The intermolecular contacts were quantified using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing the relative contributions of the contacts to the crystal packing to be H⋯H 41.7%, O⋯H/H⋯O 27.7%, C⋯H/H⋯C 17.0%, and S⋯H/H⋯S 7.5%.

1. Chemical context
Intermolecular non-covalent interactions play a critical role in determining the crystal packing and orientation of organic and coordination compounds, leading to significant changes in their properties and actions (Gurbanov et al., 2018, 2020; Kopylovich et al., 2011a,b,c; Mahmoudi et al., 2019, 2021; Mahmudov et al., 2013). In fact, various types of non-covalent bond donors and acceptors determine the supramolecular packing of heterocyclic and coordination compounds, which is a fundamental molecular descriptor for predicting the oral bioavailability as well as biocatalytic activity of small drug candidates (Abdelhamid et al., 2011; Akbari Afkhami et al., 2017; Khalilov et al., 2021; Safavora et al., 2019). This work is a continuation of studies of properties of vinylarene systems, previously obtained by the tandem acylation/[4 + 2]-cycloaddition between 3-(aryl)allylamines and maleic as an example of an IMDAV (Intra Molecular Diels–Alder Vinylarene) reaction. The IMDAV reaction is a useful tool for the one-step synthesis of benzofurans, indoles and benzothiophenes annalated with other carbo- or heterocycles (Horak et al., 2015, 2017; Krishna et al., 2022; Nadirova et al., 2020; Zubkov et al., 2016).
We report here the first case of a spontaneous oxidation reaction of an IMDAV adduct (Fig. 1) in air in DMSO at room temperature. Presumably, the DMSO acts as a mild oxidant, as it is observed in a number of other oxidation reactions – Pfitzner-Moffatt, Corey–Kim, Swern, and Kornblum oxidation (Epstein et al., 1967). The slow oxidation of (3aRS,9bRS,10RS,10aRS)-2-(4-methoxyphenyl)-1-oxo-2,3,3a,4,10,10a-hexahydro-1H-benzo[4,5]thieno[2,3-f]isoindole-10-carboxylic acid occurs under stirring of the solution in DMSO-d6 for a month. The title compound was isolated in 67% yield after a standard treatment of the reaction mixture. It should be noted that in this case, the reaction does not stop at the formation of an alcohol, but leads to the formation of an aromatic product as a result of proton migration.
2. Structural commentary
In the title compound (Fig. 2), the central six-membered ring (C3A/C4B/C4A/C9B/C10/C10A) has a slightly distorted boat conformation, with puckering parameters (Cremer & Pople, 1975) of QT = 0.5290 (17) Å, θ = 129.87 (18)° and φ = 156.7 (2)°. The fused pyrrolidine ring (N2/C1/C10A/C3A/C3) adopts an with the C3A atom as the flap [the puckering parameters are Q(2) = 0.3523 (17) Å and φ(2) = 290.0 (3)°], while the fused thiophene ring (S5/C4A/C9B/C9A/C5A) is essentially planar (r.m.s. deviation = 0.002 Å). The molecular conformation is stabilized by an O—H⋯O hydrogen bond (O3—H3⋯O6A) between the main compound and solvent molecules, as well as two intramolecular C—H⋯O hydrogen bonds (C17—H17A⋯O1 and C3A—H3AA⋯O2) in the main molecule, which form S(6) rings (O1/C1/N2/C12/C17/H17A and O2/C11/C10/C10A/C3A/H3AA; Table 1; Fig. 2; Bernstein et al., 1995). All bond lengths and angles in the main compound are comparable to those of the analogous compound ethyl 2-methyl-5,8-dioxo-6-phenyl-4a,5,6,7,7a,8-hexahydro-4H-furo[2,3-f]isoindole-4-carboxylate (CSD refcode OJIPUV; Zaytsev et al., 2021).
3. Supramolecular features and Hirshfeld surface analysis
In the , Fig. 3). These dimers form a three-dimensional network through O—H⋯O, O—H⋯S and C—H⋯O hydrogen bonds, directly with each other and through solvent molecules (Table 1). In addition, weak π–π stacking interactions are observed [Cg5⋯Cg6(x, 1 + y, z) = 3.9937 (10) Å with slippage of 2.034 Å and Cg6⋯Cg5(x, −1 + y, z) = 3.9936 (10) Å with slippage of 1.681 Å; Cg5 and Cg6 are the centroids of the C5A/C6/C7/C8/C9/C9A and C12–C17 benzene rings, respectively].
of the title compound, molecules are connected by pairs of intermolecular C—H⋯O hydrogen bonds, forming dimers with an (8) motif (Table 1Hirshfeld surfaces and their associated two-dimensional fingerprint plots were used to quantify the various intermolecular interactions, and were generated using Crystal Explorer 17.5 (Spackman et al., 2021). The 3D dnorm surfaces are plotted over a fixed color scale of −0.7960 (red) and 1.2965 (blue) a.u.
Two-dimensional fingerprint plots together with their percentage contributions are shown in Fig. 4. The crystal packing is dominated by H⋯H contacts, representing van der Waals interactions (41.7% contribution to the overall surface), followed by O⋯H/H⋯O, C⋯H/H⋯C and S⋯H/H⋯S interactions, which contribute to 27.7%, 17.0% and 7.5%, respectively. The other contacts (C⋯C 4.2%, N⋯C/C⋯N 1.3%, O⋯O 0.7%, N⋯H/H⋯N 0.1% and S⋯C/C⋯S 0.1%) only make a minor contribution to the crystal packing.
4. Database survey
A search of the Cambridge Crystallographic Database (CSD version 5.40, update of September 2019; Groom et al., 2016) yielded six entries closely related to the title compound, viz. OJIPUV (Zaytsev et al., 2021), JOGYIP (Zhou et al., 2014), LESXIS (Horak et al., 2013), QAFSUO (Zubkov et al., 2016), QAFTAV (Zubkov et al., 2016) and QUKPAP (Horak et al., 2015).
In OJIPUV and JOGYIP, P, molecules are bonded by intermolecular C—H⋯O hydrogen bonds, C—H⋯·π interactions, and π–π stacking interactions, forming three-dimensional networks. In the crystal of LESXIS (Pbca), which contains two similar molecules per O—H⋯O hydrogen bonds connect the molecules into chains parallel to the b-axis. There are also weak C—H⋯π interactions in the crystal. In the crystal structures of QAFSUO (P21/c) and QAFTAV (P21/n), the three-dimensional packings are stabilized by O—H⋯O hydrogen bonds, C—H⋯O contacts and C—H⋯π interactions. The of QUKPAP (P21/c) comprises two similar molecules, A and B, of the same The only considerable difference concerns the conformation of the allyl group. The carboxyl hydrogen atoms are involved in strong hydrogen bonds with the carbonyl atoms of neighboring molecules, giving rise to (A⋯B⋯)n chains.
In the six structures, the different groups bonded to the central twelve-membered ring systems account for the distinct intermolecular interactions in the crystals.
5. Synthesis and crystallization

6. Refinement
Crystal data, data collection and structure . The H atoms of the OH groups were placed in geometrically idealized positions and constrained to ride on their parent atoms, with O—H = 0.84 Å and Uiso(H) = 1.5Ueq(O). H atoms bound to C atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95–1.00 Å and Uiso(H) = 1.2 or 1.5Ueq(C). The dimethyl sulfoxide solvent molecule exhibits disorder at two positions in the ratio 0.8903 (18):0.1097 (18). All the methyl hydrogen atoms of the solvent molecule were assigned as deuterium and refined. The C4B and C4C atoms of the two parts of the disordered solvent molecule were refined using EADP and EXYZ commands, and other similar bond lengths of the disordered solvent molecule were refined using SADI.

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. |
