3-[2-(1,3-Benzothiazol-2-ylsulfanyl)ethyl]-1,3-oxazolidin-2-one

Abstract top

The title compound, C12H12N2S2O2, consists of a benzothiazole group and a oxazolidin-1-one linked via a flexible ethane-1,2-diyl spacer. The benzothiazole group and the oxazolidine ring are each almost planar [with maximum deviations of 0.007 (2) and 0.044 (3) Å, respectively] and make a dihedral angle of 9.35 (10)°. In the crystal structure, adjacent molecules were connected through C-H...O and C-H...N hydrogen bonds, and further extended into a three-dimensional network structure through intermolecular aromatic [pi]-[pi] stacking interactions in which the centroid-centroid distance is 3.590 (1) Å.

Comment top

N-substituted 2-oxazolidinones have been widely used as antibiotics which are effective against gram-positive bacteria (Ippolito et al., 2008; Mullera et al., 1999). In this article we provide a new synthetic route of a 2-oxazolidinone derivative. Even though the reaction mechanism has not been established, the reproducibility and high yield of the reaction should prove useful for the synthesis of this type of compound.

Herein, we report the synthesis and structure of the title compound, namely 3-(2-(benzo[d]thiazol-2-ylthio)ethyl)-oxazolidin-2-one (Fig.1). As shown in Fig. 2, a two-dimensional supramolecular network was formed by hydrogen bonds (Table 1) and weak π-π stacking interactions between the phenyl rings and the thiazolyl rings of adjacent molecules with a centroid-centroid distances of 3.590 Å along b direction.

Experimental top

A mixture of 2-mercaptobenzothiazole (6.69 g, 0.04 mol), potassium carbonate (8.29 g, 0.06 mol) and ethanol (250 ml) was heated and stirred in a 500 ml flask. Bis(2-chloroethyl)amine hydrochloride (7.14 g, 0.04 mol, dissolved in 100 ml ethanol) was added dropwise into the flask when the mixture was heated to 353 K, and the mixture was further stired at 353 K for 8 h. After cooling, the precipitate was filtered, washed with ethanol and water, and recrystallized from ethanol to obtain a flaxen powder. Yield: 68%. 1H NMR (CDCl3, 400 MHz):3.60 (t, 2H), 3.74 (m, 4H), 4.3 (t, 2H), 7.45 (m, 2H), 7.77 (d, 1H), 7.79 (d, 1H). 13C NMR (CDCl3, 125 MHz): 31.17, 43.81, 45.58, 61.97, 121.40, 121.41, 124.55, 126.20, 135.26, 152.86, 158.40, 165.71.

Refinement top

The H atoms were placed at calculated positions in the riding model approximation (C—H 0.95–0.99 Å), with their temperature factors were set to 1.2 times those of the equivalent isotropic temperature factors of the parent atoms.

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.
