4-(Methylsulfanyl)-2-(p-toluenesulfonamido)butanoic acid

L. Wang, Z. Liu and Y. L. Wang

Abstract top

In the title compound, C12H17NO4S2, the carboxyl groups link the molecules into centrosymmetric dimers through O-H...O hydrogen bonds. An N-H...O hydrogen bond between the NH group of the L-methionine unit and a neighbouring carboxyl group, together with a complementary C-H...O contact to one O atom of the sulfonyl group, link the dimers into one-dimensional chains along the crystallographic b axis.

Comment top

The title compound (Fig. 1) was synthesized from 4-toluenesulfonyl chloride and L-methionine. It is closely related to the previously reported N-tosyl-L-glutamic acid (Zachara et al., 2005).

Related literature top

The title compound is closely related to the previously reported N-tosyl-L-glutamic acid (Zachara et al., 2005).

Experimental top

A solution of L-methionine (0.005 mmol) and NaOH (0.015 mmol) in water (15 ml) was added to an ethanol solution of 4-toluenesulfonyl chloride (0.005 mmol). After stirring at 348 K for 40 min, crystals of the title compound were obtained by slow evaporation of the reaction mixture at room temperature.

Refinement top

H atoms bound to C or O atoms were placed geometrically with C—H = 0.93–0.97 Å or O—H = 0.82 Å and refined as riding with Uiso(H) = 1.2 or 1.5Ueq(C/O). The H atom of the NH group was located in a difference Fourier map and refined with an isotropic displacement parameter, without restraint.

Special details top

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.
