(S)-(–)-Methyl 2-(p-tolyl­sulfon­yloxy)­propanoate

Abstract

In the title compound, C₁₁H₁₄O₅S, there is an intra­molecular C—H⋯O hydrogen bond, for which the C—C—S—O torsion angle involving the acceptor and donor atoms is 2.4 (4)°. The dihedral angle between the benzene ring and the methoxy­carbonyl plane is 52.7 (4)°. In the crystal structure, mol­ecules are linked via inter­molecular C—H⋯O hydrogen bonds, forming a mol­ecular chain along the b axis.

Comment

(S)-(-)-methyl 2-(p-toluenesulfonyloxy)propanoate is an important fine chemical, which can be used for many fields such as chiral pesticide, organometallic chemistry, etc. (Talbert et al., 1974). The bond lengths and angles of the title compound are within normal ranges (Allen et al., 1987). In the crystal structure, molecules are linked via intermolecular C—H···O hydrogen bonds, which with intramolecular C—H···O hydrogen bonds seem to be effective in the stabilization of the crystal. As can be seen from the packing diagram (Fig. 2), the molecules are stacked along the a axis.

Experimental

The title compound was prepared according to the literature method (Chan et al., 1975). The crystals were obtained by dissolving the title compound (500 mg, 2 mmol) in ethyl acetate (20 ml) and evaporating the solvent slowly at room temperature for about 7 d.

Refinement

H atoms were positioned geometrically (C—H = 0.93–0.98 Å) and constrained to ride on their parent atoms, with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(methyl C).

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.

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.
