Dicyclo­hexyl­ammonium (S)-2-azido-3-phenyl­propano­ate

Abstract

The asymmetric unit of the title compound, C₁₂H₂₄N⁺·C₉H₈N₃O₂ ⁻, consists of two dicyclo­hexyl­ammonium cations linked to two (S)-2-azido-3-phenyl­propano­ate anions by four short N—H⋯O hydrogen bonds with N⋯O distances in the range 2.712 (3)–2.765 (3) Å. The dicyclo­hexyl­ammonium cations and the aryl and carboxyl­ate groups of the anion are related by a pseudo-inversion centre, with overall crystallographic inversion symmetry for the structure broken by the chirality of the α-C atoms of the anions.

Comment

Recent investigations into the development of new molecules to act as potential inhibitors of malarial proteases (Gardiner et al., 2009) resulted in the synthesis of the title compound (I) through utilization of the azido-transfer reagent imidazole-1-sulfonyl azide hydrochloride (Goddard-Borger & Stick, 2007). The structure of (I) is shown in Fig. 1 to consist of two dicyclohexylammonium cations and two (S)-2-azido-3-phenylpropanoate anions linked by four N—H···O hydrogen bonds with N···O = 2.712 (3) - 2.765 (3) Å, [graph set R₄⁴(12); Etter et al., 1990] (Table 1). The carboxylate C—O bond lengths span a narrow range from 1.247 (4) - 1.249 (4) Å. This structural format is similar to a number of other dimeric dicyclohexylammonium carboxylate salts (e.g. Ng et al., 2001; Zain & Ng, 2007; Judaš & Portada, 2008) in which the ion-pairs are disposed about a crystallographic inversion centre. In the present structure, the Cy₂NH₂⁺ cations and the aryl and carboxylate groups of the anions are related by a pseudo-inversion centre, with overall crystallographic inversion symmetry for the structure broken by the chirality of the α-carbon of the anions.

Experimental

(L)-phenylalanine (1.00 g, 6.05 mmol), imidazole-1-sulfonyl azide hydrochloride (1.52 g, 7.25 mmol), and copper sulfate pentahydrate (0.015 g, 0.06 mmol) were dissolved in methanol (30 ml) at 273 K. Anhydrous potassium carbonate (1.00 g, 7.24 mmol) was introduced over 5 minutes with stirring. The heterogeneous mixture was allowed to return to room temperature, and stirred for a further 16 h. Volatiles were removed in vacuo and the resulting material was suspended in water (90 ml). The mixture was acidifed to pH < 2 by dropwise addition of concentrated aqueous hydrochloric acid solution (37%). The resulting mixture was extracted with ethyl acetate (3 x 60 ml). The organic phases were combined, dried over anhydrous magnesium sulfate and volatiles were removed in vacuo to afford a crude oil. The crude oil was purified by flash chromatography (89:10:1 hexane:ethyl acetate:acetic acid) and the resulting oil dissolved in an excess of diethyl ether at 273 K. Dicyclohexylamine was added dropwise until pH > 10 was achieved by water-wet litmus paper, resulting in precipitation of (I). This was filtered, washed with excess cold diethyl ether and dried in vacuo to give (I) as an opaque white solid. Yield 0.91 g, 82%. Colourless crystals suitable for X-ray diffraction studies were grown by slow evaporation of an acetone/methanol solution of the compound.

Refinement

The carbon-bound H atoms were constrained as riding atoms with C—H = 0.95 Å. The ammonium protons were located in difference Fourier maps and constrained with N—H 0.85 Å. U_iso(H) values were set at 1.2U_eq of the parent atom. In the absence of significant anomalous scatterers in the compound, Friedel equivalents were merged with the absolute configuration assigned from the chirality of the L-phenylalanine precursor.

Special details

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 e.s.d.'s 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 > σ(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.
