The title compound, C11H15NO6S, features a distorted tetrahedral geometry for the S atom. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C—C—S—O torsion angle = −160.81 (7)°], whereas the other lies well below the plane [C—C—S—O = −29.66 (8)°]. In the crystal, O—H⋯O and C—H⋯O hydrogen bonds link the molecules into chains parallel to the b axis.

To a solution of L-threonine (3 mmol, 0.618 g) in distilled water (10 ml), 4-methoxybenzene sulphonyl chloride (3 mmol, 0.357 g) was suspended. The pH of the solution was maintained at 8 by continuously adding 1M sodium carbonate solution throughout the reaction at room temperature. After the completion of the reaction, the pH was adjusted to 2 using 1N HCl solution which resulted in the formation of the precipitate which was filtered, dried and recrystallized in methanol to yield the title compound.
Atoms H1N1, H1O5 and H1O6 were located from a difference Fourier map and refined freely [N–H = 0.887 (17) and O–H = 0.81 (2)–0.845 (19) Å]. The remaining H atoms were positioned geometrically [C–H = 0.93–0.98 Å] and were refined using a riding model, with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl groups. 2444 Friedel pairs were used to determine the absolute configuration.

The sulfonamide O2 atom is approximately co-planar with the benzene ring [the O2-S1-C1-C6 torsion angle is -160.81 (7)°] whereas the O3 atom lies well below the plane [O3-S1-C1-C6 = -29.66 (8)°].In the

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

The chemistry of sulfonamides is of interest as they show distinct physical, chemical and biological properties. Sulfonamides are used as anticancer, anti-inflammatory and antiviral agents (Supuran et al., 2003; Scozzafava et al., 2003). Amino acid-derived sulfonamides are shown to be active against Procollagen C-terminal protease, which is a member of the metzincin enzyme family (Robinson et al., 2003; Delaet et al., 2003).
The asymmetric unit of the title compound is shown in Fig. 1. The S atom is tetrahedrally bonded within a CNO2 donor set with the greatest deviation manifested in the O2—S1—O3 angle of 120.08 (5)°. The sulfonamide O2 atom is approximately co-planar with the benzene ring [the O2-S1-C1-C6 torsion angle is -160.81 (7)°] whereas the O3 atom lies well below the plane [O3-S1-C1-C6 = -29.66 (8)°].
In the crystal structure (Fig. 2), intermolecular O—H···O and C—H···O hydrogen bonds (Table 1) link the molecules into chains parallel to the b axis.
