Crystal structure of (1S,2R)-2-[(3R,4S)-3-methyl-4-phenyl-1,2,3,4-tetra­hydro­isoquinolin-2-yl]-1,2-di­phenyl­ethanol

The title chiral β-amino alcohol was isolated as one of two diastereomeric β-amino alcohols, the title mol­ecule being found to be the (S,R) diastereoisomer. In the crystal, mol­ecules are packed in a herringbone manner parallel to (103) and (10) via weak C—H⋯O and C—H⋯π(ring) inter­actions.

Abstract

The synthesis and crystal structure of the title compound, C₃₀H₂₉NO, are described. This compound is a member of the chiral di­hydro­iso­quinoline-derived family, used as building blocks for functional materials and as source of chirality in asymmetric synthesis, and was isolated as one of two diastereomeric β-amino alcohols, the title mol­ecule being found to be the (S,R) diastereoisomer. In the crystal, mol­ecules are packed in a herringbone manner parallel to (103) and (10) via weak C—H⋯O and C—H⋯π(ring) inter­actions. Hirshfeld surface analysis showed that the surface contacts are predominantly H⋯H inter­actions (ca 75%). The crystal studied was refined as a two-component inversion twin.

Chemical context  

β-amino alcohols exhibit a broad spectrum of biological activities and are used as anti­bacterial and tuberculostatic agents (Yendapally & Lee, 2008 ▸). In particular, chiral β-amino alcohols are very important chiral mol­ecules that are used as building blocks and structural motifs in pharmaceutically active mol­ecules and natural products and which serve as the main sources of chirality in asymmetric synthesis (Lee et al., 2003 ▸; Malkov et al., 2007 ▸; Guo et al., 2017 ▸).

Among this family of chiral amino-alcohols is the title compound, (I), which we prepared through the alkyl­ation of tetra­hydro­iso­quinoline by the opening racemic trans-stilbene oxide reaction. Two diastereoisomers were obtained in a 1:1 ratio as determined by ¹H NMR analysis on the crude mixture. These diastereoisomers were separated by column chromatography. The title mol­ecule was found to be the (S,R) diastereoisomer.

Structural commentary  

The structure of (I) was confirmed using single crystal X-ray diffraction. The asymmetric unit of the ortho­rhom­bic unit cell comprises a single mol­ecule, shown in Fig. 1 ▸. The tetra­hydro­iso­quinoline unit is substituted by a methyl group in position 3, a phenyl substituent in position 4 and a β-alcohol substituent at the N atom. The heterocyclic ring exhibits a half-chair conformation, with atom C3 deviating by 0.706 (3) Å from the plane formed by atoms C1/N2/C4/C9/C10. The substituents in positions 3 and 4 of the heterocyclic ring are in axial positions. The mol­ecular structure of (I) is stabilized by an intra­molecular hydrogen bond between the hy­droxy O19—H19 group and atom N2, and to a lesser extent, between the aromatic C21—H21 and the phenyl group in position 4 (Table 1 ▸). By reference to two unchanging chiral C18 and C19 atoms, the mol­ecule was found to be the (18R,19S) diastereoisomer resulting from the reaction of tetra­hydro­iso­quinoline and the (S,S) trans-stilbene oxide enanti­omer.

This structure was confirmed through the means of usual 1D and 2D NMR experiments. NMR data show that the trans diequatorial arrangement of H3 and H4 is suggested by the coupling constant between H3 and H4 in ¹H NMR (J _3,4 ∼0 Hz), so the substituents C3-methyl and C4-phenyl are in an axial disposition. The absolute configurations of carbon atoms C18 and C19 were deduced from the NOESY maps to be R and S, respectively (Fig. 2 ▸).

Supra­molecular features  

In the crystal, mol­ecules of (I) pack with no classical hydrogen bonds: the potential donor hydroxyl group is involved in an intra­molecular inter­action with the N atom. However, the oxygen atom acts as an acceptor in the short contact C6—H6⋯O19 (−x,  + y,  − z) with an O19⋯H distance of 2.57 Å, which is of the same order of magnitude of the H⋯O van der Waals distance (2.60 Å), whereas C—H⋯O contacts are frequently reported with H⋯O separations shorter than 2.4 Å (Taylor & Kennard, 1982 ▸). The N atom does not play a role in the packing as it is buried inside the structure. Nevertheless, these directed C—H⋯O inter­actions make an important contribution to the packing: zigzagging along the [010] direction, they pair mol­ecules in ribbons, placing the iso­quinoline moieties parallel to the (103) plane on both sides but without overlapping. The ribbon cohesion is reinforced by C—H⋯π inter­actions involving the phenyl group in position 4 and those attached to the β-alcohol part and which flank the ribbon, as shown in Fig. 3 ▸. They stack in the [100] direction as columns arranged in a herringbone manner but avoiding π-π- stacking (Fig. 4 ▸).

Database survey  

A search of the Cambridge Structural Database, CSD (Version 5.40; ConQuest 1.21; Groom et al., 2016 ▸) found 495 structures of tetra­hydro­iso­quinoline derivatives. Limiting the search to compounds with tri-substitutions on positions C3, C4 and the secondary amine N reduces the number of structures to seven: ADAGOC (Gzella et al., 2006 ▸), JIPKEZ (White et al., 2007 ▸), TIBPIE (Ben Ali et al., 2007 ▸), VAHJOG (Davies et al., 2016 ▸), XOSDUE (Gzella et al., 2002 ▸), YEKKIK (Shi et al., 2012 ▸) and ZIFSUE (Guo et al., 2013 ▸). Except for the racemic VAHJOG, they all crystallize in the same P2₁2₁2₁ space group. The structures of ZIFSUE, TIBPIE, VAHJOG, JIPKEZ and (I) superimpose well over the heterobicycle with the same conformation, unlike ADAGOC and XOSDUE which have a different half-chair configuration. The amino alcohol TIBPIE is obviously the closest related structure, differing in the N substitution of a cyclo­hexane carrying the hydroxyl group which is involved in the intra­molecular hydrogen bond.

Hirshfeld surface analysis  

The inter­molecular inter­actions were qu­anti­fied using Hirshfeld surface analysis and the associated two-dimensional fingerprint plots using CrystalExplorer17.5 (Turner et al., 2017 ▸). The electrostatic potentials were calculated using TONTO, integrated within CrystalExplorer. The analysis of inter­molecular inter­actions through the mapping of d _norm presented in Fig. 5 ▸ compares the contact distances d _i and d _e from the Hirshfeld surface to the nearest atom inside and outside, respectively, with their respective van der Waals radii. The blue, white and red colour conventions recognize the inter­atomic contacts as longer, at van der Waals separations and short inter­atomic contacts. The C—H⋯O contacts are identified in the d _norm-mapped surface as two red spots showing the inter­action between the neighbouring mol­ecules (Fig. 5 ▸ a). The overall two-dimensional fingerprint plot derived form the Hirshfeld surface is a useful method to summarize the frequency of each combination of d _e and d _i across the surface of the studied mol­ecule, encompassing all inter­molecular contacts (Fig. 5 ▸ b). The delineated fingerprint plots (Fig. 5 ▸ b and 6a,c) focus on specific inter­actions, providing information about the major and minor percentage contribution of inter­atomic contacts in the compound. The H⋯H inter­actions account for the three quarters of the total (73.7%) with an evident sting at about d _i = d _e = 1.1 Å (Fig. 5 ▸ b). The C⋯H/H⋯C plot, which refers to the C—H⋯π inter­actions previously described (22.7%,) shows two broad symmetrical wings at about d _i + d _e = 2.8 Å (Fig. 6 ▸ a). These inter­actions are observed as red regions on the shape-index surface (Fig. 6 ▸ b). The absence of C⋯C contacts, highlighted by the Hirshfeld surface with high curvedness delineated by dark-blue edges, confirms that no π–π stacking inter­actions take place in the crystal packing (Fig. 6 ▸ c,d). The third marginal contribution is O⋯H/H⋯O (3.6%) with a pair of sharp spikes at about d _i + d _e = 2.4 Å, symmetrically disposed with respect to the diagonal, indicating the presence of inter­molecular C—H⋯O inter­actions, which play a role in ordering the mol­ecules inside the crystal.

Synthesis and crystallization  

The title β-amino alcohol was obtained by mixing racemic trans-stilbene oxide (5.1g, 26mmol) with (3R,4S)-3-methyl-4-phenyl-1,2,3,4-tetra­hydro­isoquinoleine (3g, 13mmol), which was prepared according to the method of Bohé et al. (1999 ▸).

The mixture was heated at 353.15 K for 48 h in CF₃CH₂OH (65 ml), the reaction being monitored by TLC. Two diastereoisomers were obtained in a 1:1 ratio. These diastereoisomers were separated by column chromatography. Only the title compound (white solid) was successfully recrystallized. Crystals were grown by placing this dastereoisomer in a minimum amount of hot heptane. [α] _D ²⁵ = −23.6 (c 1, CHCl₃), m.p. 425 K.

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms were placed in calculated positions (C—H = 0.93–0.98 Å) and refined as riding with U _iso(H) = 1.2U _eq(C). The crystal studied was refined as a two-component inversion twin.

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.
