The 17H25NO7S, contains two independent molecules, which are enantiomers forming a hydrogen-bonded dimer associated with two R22(7) patterns. In each molecule, one ethyl group from the two available ethyl ester functional groups is disordered. In one molecule, the ethyl group of the ester function from an α-carboxylic acid is positionally disordered over two sets of sites with occupancies of 0.66:0.34. In the second molecule, it is the ethyl group in the γ-ester function that is disordered over two sets of sites with occupancies of 0.58:0.42.

A solution of (0.04 mmole, 14.7 mg) K2[OsO2(OH)4] in water (2.5 ml) and chloramine-T (1.5 mmole, 423 mg) was added to a solution of diethyl 2-ethylfumarate (20 mg, 0.1 mmole) and (DHQD)2PHAL (0.05 mmole, 39 mg) in CH3CN (1.25 ml). After 1 h stirring at room temperature a second fraction of diethyl 2-ethylfumarate (180 mg, 0.9 mmole) in CH3CN (1.25 ml) was added to the reaction mixture. After 5 h, a solution of Na2SO3 (357 mg) in water (5.4 ml) was added an the reaction mixture was extracted 3 times with AcOEt (5.4 ml). The fraction was then washed with brine and dried under MgSO4. The solvent was removed and the title compound was recrystallized in cyclohexane by slow evaporation at ambient temperature yielding colourless crystals in the form of relatively large prisms.
All N-bound and O-bound H atoms were located in a difference Fourier maps and later restraint to a distance O–H = 0.82 (2) Å with Uiso(H)=1.5Ueq(O) and N–H = 0.88 (2) Å with Uiso(H)=1.2Ueq(N) in order to stabilize their coordinates during the final step of the
All other H atoms were introduced at calculated positions and refined as riding atoms with C–H = 0.96–0.98 Å, with displacement parameters Uiso(H) equal to 1.5Ueq(C) for methyl and 1.2Ueq(C) for all other H atoms. Restraints (SADI, SIMU, DELU) were used to stabilize the of the disordered diethyl groups. The occupancies of the disordered parts were fixed during the final cycles of the refinements.Data collection: CrysAlis PRO (Agilent, 2010); cell

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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) 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. |

In the present work, as a part of an on-going study of asymmetric syntheses of optically pure β-substituted β-hydroxy aspartates (Wehbe et al., 2003a,b,c; Mekki et al., 2011a,b), the structure of a new compound, threo-diethyl 2-ethyl-2-hydroxy-3-(4-methylphenylsulfonamido)succinate, is described. The key step of the synthesis is the regiospecific Sharpless aminohydroxylation on an ethyl fumarate derivative.
The crystal structure is made up by racemic dimers formed by two independent homochiral molecules ((2S,3S) and (2R,3R) for (I) and (II), respectively). They are bonded by non-covalent NH···O and OH···O hydrogen bonds (Fig. 1) forming two R22(7) patterns (Etter, 1990; Bernstein et al., 1995), where the H···O distances range from 2.10 (2) Å to 2.232 (19) Å and the D—H···O angles from 142 (2) to 161.9 (18) ° (Table 1). In order to get an idea of the relative strength of the NH···O and OH···O hydrogen bonds the intersection of the Van der Waals surfaces of donor hydrogen and acceptor was calculated using the program Jmol (Jmol, 2011; 'contact' command with 'full' and 'hbond' options). The resulting Fig. 2 shows clearly that the Van der Waals interaction zones between the hydroxyl groups and the carbonyl ester O atoms are more important than those between the hydroxyl groups and the secondary amine group. The latter interaction zones are much smaller than the former ones. A calculation based on the electron density and its derivatives (Johnson et al., 2010; calculation done in Jmol using the 'contact' command with 'nci' and 'hbond' as options) gives slightly different results (Fig. 3), in the sense that one of the OH···O interactions appears to be negligible. The relevant Van der Waals surfaces may be inspected in the enhanced Jmol picture in Fig. 4. This pictorial view of the non-covalent interaction regions is not completely in agreement with what could be concluded from the directionality of the interaction which is greater for nitrogen as hydrogen bond donor than for oxygen (Table 1). The dimeric structure bears much similarity with those reported recently for the two concomitant β-benzyl β-hydroxy aspartate analogue polymorphs (Mekki et al., 2011a).
The two independent homochiral molecules are very approximately related by a local inversion center between the two molecules. That this local center is only very approximate, can be clearly seen in Fig. 5, which shows the best superposition of the (2S,3S) molecule (I) and the (2S,3S) inversion center related molecule (II) as calculated with Olex2 (Dolomanov et al., 2009). The root-mean-squared deviation (considering the majority disordered parts only) between the two molecules is 0.780 Å. The main conformational differences between molecules (I) and (II) stem from the orientation of the ethyl ester moiety in both residues. This is well illustrated by the torsion angles C9—O5—C4—C3 (-4.2 (2)° and 173.6 (3)° for molecules (I) and (II), respectively) and C1–01-C7—C8 (-165.5 (3)° and -88.6 (2)° for molecules (I) and (II), respectively).
In both molecules, the S1—N1(H1)—C2 pseudo-torsion angle [140.2 (1)° for (I) and -143.3 (1)° for (II)] implies a slight pyramidalization of the sulfonamide moiety.
