Crystal structure of (1S,2R,4S)-1-[(morpholin-4-yl)meth­yl]-4-(prop-1-en-2-yl)cyclo­hexane-1,2-diol

Besides intra­molecular O—H⋯N hydrogen bonds, the crystal structure displays inter­molecular O—H⋯O and C—H⋯O hydrogen bonds linking the mol­ecules into undulating layers parallel to the (01) plane.

Abstract

The asymmetric unit of the title compound, C₁₄H₂₅NO₃, contains two independent mol­ecules with similar geometry. The morpholine and cyclo­hexane rings of both mol­ecules adopt a chair conformation. Intra­molecular O—H⋯N hydrogen bonds are observed. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds into chains parallel to the [101] direction. The chains are further connected through C—H⋯O hydrogen bonds forming undulating layers parallel to the (-101) plane. The absolute configuration was assigned by reference to an unchanging chiral centre in the synthetic procedure.

Chemical context  

1,2-Amino­alcohols are important building blocks in the synthesis of natural products, pharmaceuticals and other materials (Möller, 1957 ▸). The classical synthetic approach towards amino­alcohols involves amino­lysis of epoxides with an excess of amines. There are some limitations to this classical approach, such as the requirement of elevated reaction temperatures in the case of less reactive amines, lower reactivity for sterically crowded amines/epoxides, and poor regioselectivity of the epoxide ring opening (Sello et al., 2006 ▸). To obviate these problems, various methodologies to undertake epoxide opening under milder conditions have been developed (Surendra et al., 2005 ▸), but there are still many limitations, such as the formation of bis­alkyl­ated products, longer reaction times, stoichiometric amounts of catalysts and harsh reaction conditions.

Recently, we have shown that calcium(II) compounds are very useful, environmentally friendly catalysts for several acid-catalysed reactions (Harrad et al., 2010 ▸). Moreover, calcium triflate works under almost neutral conditions. In a continuation of our ongoing program on the amino­lysis of 1,2-epoxides using a mild, practical and efficient method under solvent-free conditions (Outouch, Boualy, Ali et al., 2011 ▸; Outouch, Boualy, El Firdoussi et al., 2011 ▸; Outouch et al., 2014 ▸), we report herein the synthesis and crystal structure of a new amino­diol from ep­oxy­perillyl alcohol, which can be used as a chiral ligand for catalytic enanti­oselective transformations. The title compound was prepared by condensation of ep­oxy­perillyl alcohol with morpholine using a catalytic amount of Ca(CF₃COO)₂ under solvent-free conditions according to the procedure described previously (Outouch, Boualy, Ali et al., 2011 ▸; Outouch, Boualy, El Firdoussi et al., 2011 ▸).

Structural commentary  

As shown in Fig. 1 ▸, there are two mol­ecules in the asymmetric unit of the title compound. In both mol­ecules, the cyclo­hexane rings adopt a chair conformation, with atoms C1/C4 and C15/C18 as flaps. The hydroxyl groups are all in axial positions. A chair conformation is also observed for the morpholine rings, with the N and O atoms as flaps. The mol­ecular conformation is enforced by an intra­molecular O—H⋯N hydrogen bond (Table 1 ▸).

Supra­molecular features  

In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds (Table 1 ▸) involving the hydroxyl groups into chains running parallel to the [101] direction (Fig. 2 ▸). Moreover, the chains are further connected via C—H⋯O hydrogen bonds, forming undulating layers parallel to the (01) plane.

Database survey  

The structures of related 1,4-substituted cyclo­hexane-1,2-diols have been reported recently by Byrne et al. (2004 ▸), Blair et al. (2007 ▸, 2010 ▸), Dams et al. (2004 ▸), Outouch, Boualy, Ali et al. (2011 ▸) and Outouch, Boualy, El Firdoussi et al. (2011 ▸). As found for the title compound, the cyclo­hexane-1,2-diol rings of these compounds adopt a chair conformation.

Synthesis and crystallization  

A mixture of morpholine (5.1 mmol) and ep­oxy­perillyl alcohol (5 mmol), prepared by epoxidation of (S)-(−) perillyl alcohol, was added to 5 mol% of Ca(CF₃CO₂)₂ under solvent-free conditions. The mixture was stirred at 313 K for 72 h. After the reaction had finished, the mixture was extracted with ethyl acetate (3 × 10 ml), dried over Na₂SO₄ and the solvent was removed at reduced pressure. The title compound was purified by column chromatography on silica gel using hexa­ne/ethyl acetate (1:1 v/v) as eluent (yield 49%). Single crystals suitable for X-ray analysis were obtained by slow evaporation of the solvents.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The H atoms attached to oxygen could be found in a difference Fourier map and were freely refined. All other H atoms were placed in idealized positions with d(C—H) = 0.95–0.99 Å and refined using a riding model, with U _iso(H) = 1.2 U _eq(C) or 1.5 U _eq(C) for methyl H atoms. A rotating model was adopted for the methyl groups. The absolute configuration was not established by anomalous scattering effects, the enanti­omer was assigned by reference to an unchanging chiral center in the synthetic procedure.

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.
