Abstract

In the title compound, C28H34N2O5, the adjacent ester and nitro-benzene substituents are connected via an intra-molecular methyl-ene-C-H⋯π(nitrobenzene) inter-action and the mol-ecule approximates to a U-shape. The di-hydro-pyrrole ring (r.m.s. deviation = 0.003 Å) is almost co-planar with the carboxyl-ate residue [Cm-N-C1-Oc (m = methine, c = carbox-yl) torsion angle = 1.8 (4)°] but is orthogonal to the 4-meth-oxy-benzene ring [dihedral angle = 84.34 (17)°]. In the crystal, methyl-ene-C-H⋯O(carbon-yl) inter-actions lead to linear supra-molecular chains along the b-axis direction, which pack without directional inter-actions between them. The analysis of the calculated Hirshfeld surface points to the importance of weak inter-atomic H⋯H, O⋯H/H⋯O and C⋯H/H⋯C contacts in the crystal.

Chemical context

The reaction of an unsaturated halide species with an alkene, in the presence of both a base and a organopalladium catalyst, to form a substituted alkene, is termed the Heck reaction (Heck, 1982 ▸; Crisp, 1998 ▸). As part of our investigations into the scope of the Heck reaction in the total, enanti­oselective and efficient synthesis of pyrrolidine alkaloids, such as the natural product (–)-codonopsinine (Severino & Correia, 2001 ▸), an enecarbamate containing the chiral auxiliary residue, 8-(4-nitro­phen­yl)menthol, was submitted to a Heck aryl­ation reaction with 4-meth­oxy­phenyl­diazo­nium tetra­fluoro­borate. The reaction yielded the title compound, 8-(4-nitro­phen­yl)menthyl 2-(4-meth­oxy­phen­yl)pyrroline-3-carboxyl­ate, (I), as the sole crystalline material (Machado, 2001 ▸). Herein, the crystal and mol­ecular structures of (I) are described along with an analysis of the calculated Hirshfeld surfaces.

Structural commentary

The mol­ecular structure of (I), Fig. 1 ▸, comprises a 1-, 2- and 5-substituted cyclo­hexyl ring (chair conformation) with the chirality at these equatorially substituted centres, i.e. C14, C15 and C18, established from the synthesis, being R, S and R, respectively. The di­hydro­pyrrole ring is essentially planar, with an r.m.s. deviation of 0.003 Å for the five constituent atoms; the N1 and C5 atoms lie 0.037 (2) and 0.030 (3) Å to opposite sides of the plane. The chirality of the C2 centre is R. The carboxyl­ate residue is almost co-planar with the five-membered pyrrole ring as seen in the value of the C2—N1—C13—O2 torsion angle of 1.8 (4)°. However, the appended 4-meth­oxy­benzene ring is almost orthogonal to the pyrrole ring, forming a dihedral angle of 84.34 (17)°; the meth­oxy group is co-planar with the benzene ring with the C12—O3—C9—C10 torsion angle being 178.0 (4)°. In the same way, the nitro group is co-planar with the benzene ring to which it is connected with the O5—N2—C27—C28 torsion angle being 1.2 (5)°. In the mol­ecule, there is a close pyrrole-methyl­ene-C5—H⋯π(C24–C29) inter­action, Table 1 ▸, which connects the substituents at the cyclo­hexyl-C14 and C15 atoms which lie to the same side of the mol­ecule and which define a shape corresponding to the letter U.

Supra­molecular features

The mol­ecular packing of (I) features a number of weak non-covalent contacts as discussed below in the Hirshfeld surface analysis (§4). In accord with the distance criteria assumed in PLATON (Spek, 2009 ▸), there is only one directional inter­action of note, Table 1 ▸. Thus, methyl­ene-C19—H⋯O2(carbon­yl) inter­actions connect mol­ecules into a linear supra­molecular chain along the b-axis direction, Fig. 2 ▸ a. These assemble in the crystal with no directional inter­actions between them, Fig. 2 ▸ b.

Hirshfeld surface analysis

The Hirshfeld surfaces calculated for (I) were conducted as reported recently for a related organic mol­ecule (Zukerman-Schpector et al., 2017 ▸) and provide information on the influence of short inter­atomic non-bonded contacts upon the mol­ecular packing. With reference to Fig. 3 ▸, in addition to the bright-red spots near the methyl­ene-H19B and carbonyl-O2 atoms, representing the C—H⋯O inter­action listed in Table 1 ▸, the diminutive-red spots near the O3, C9 and H17B atoms, corresponding to short inter­atomic O3⋯H17B and C9⋯H17B contacts (Table 2 ▸), on the Hirshfeld surface mapped over d norm suggest they also have some influence on the mol­ecular packing in the crystal. The effect of other short inter­atomic O⋯H/H⋯O and C⋯H/H⋯C contacts listed in Table 2 ▸ are also viewed as faint-red spots near the O3, H4, O5 and H20B atoms in Fig. 3 ▸. The influence of the short inter­atomic O⋯H, C⋯H and H⋯H contacts in the mol­ecular packing are also illustrated in Fig. 4 ▸ a and b, which show the Hirshfeld surface mapped over the shape-index property and d norm, respectively. The intra­molecular C—H⋯π contact between the pyrrole-H5A atom and the nitro­benzene ring [H5A⋯Cg(C24–C29) = 2.67 Å, C5⋯Cg(C24–C29) = 3.612 (3) Å and CH5A⋯Cg(C24–C29) angle = 163°] is shown as a black-dotted line within the Hirshfeld surfaces mapped over the electrostatic potential in Fig. 5 ▸.

The overall two-dimensional fingerprint plot for (I), Fig. 6 ▸ a, and those delineated into H⋯H, O⋯H/H⋯O and C⋯H/H⋯C contacts (McKinnon et al., 2007 ▸) are illustrated in Fig. 6 ▸ b-d, respectively. The fingerprint plots also reflect the presence of the short inter­atomic contacts on the packing, Table 2 ▸. This is also evident from the percentage contribution from different inter­atomic contacts to the Hirshfeld surface summarized in Table 3 ▸: the H⋯H, O⋯H/H⋯O and C⋯H/H⋯C inter­atomic contacts make the greatest contribution to the Hirshfeld surface and account for 97.9% of the overall surface. The broad feather-like distribution of points with a peak at d e + d i ∼2.3 Å in the fingerprint plot delineated into H⋯H contacts in Fig. 5 ▸ b represent H⋯H contacts in the structure and make the greatest, i.e. 61.7%, contribution to the surface. The inter­atomic O⋯H/H⋯O contacts having a 23.9% contribution to the Hirshfeld surface arise from the C—H⋯O contact (Table 1 ▸) and short inter­atomic O⋯H/H⋯O contacts (Table 2 ▸), and are viewed as the pair of green aligned points beginning at d e + d i ∼2.6 Å and a pair of jaw-shaped distribution of points in the range d e + d i ∼2.5–2.6 Å in Fig. 6 ▸ c. The points distributed around the pair of forceps-like peaks at d e + d i ∼2.8 Å in the fingerprint plot delineated into C⋯H/H⋯C contacts (Fig. 6 ▸ d) represent the formation of such intra- and inter-layer contacts in the crystal. The small contribution from other inter­atomic contacts summarized in Table 3 ▸ appear to have a negligible impact on the mol­ecular packing.

Database survey

The (1R,2S,5R)-menthyl substrate is important as a chiral source for the synthesis of natural products and, as such, has been found in a number of crystal structures related to (I). Owing to the dictates of the chirality at the C1 and C2 positions, a parallel alignment of the substituents at these positions usually result in U-shaped geometries (Aoyagi et al., 1998 ▸; Singh et al., 1990 ▸; Streith et al., 1995 ▸), except in circumstances where steric hindrance precludes such an arrangement (Comins & Killpack, 1992 ▸).

Synthesis and crystallization

As detailed previously (Machado, 2001 ▸), for the Heck aryl­ation of (1R,2S,5R)-5-methyl-2-[2-(4-nitro­phen­yl)propan-2-yl]cyclo­hexyl 2,3-di­hydro-1H-pyrrole-1-carboxyl­ate, a stoichiometric qu­antity of 4-meth­oxy­phenyl­diazo­nium tetra­fluoro­borate was used along with 1 mol equivalent of Pd0 and 400 mol equivalent of sodium acetate. The reaction was conducted in aceto­nitrile at room temperature for 15 min, yielding (1R,2S,5R)-5-methyl-2-[2-(4-nitro­phen­yl)propan-2-yl]cyclo­hexyl (2S)-2-(4-meth­oxy­phen­yl)-2,5-di­hydro-1H-pyrrole-1-carboxyl­ate and the title compound, (I), the latter being the only crystalline product, obtained as irregular colourless chunks by slow evaporation of an n-hexa­ne–ethyl acetate solution (8:2 v/v).

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.
