In the title compound, C22H18FNO3S2, the five-membered thiazolidine ring is planar (r.m.s. deviation = 0.003 Å) and forms dihedral angles of 70.2 (3), 73.16 (17) and 10.32 (14)° with the cyclopropane, fluorobenzene and methylthiobenzene rings, respectively. The sum of the bond angles around the thiazolidine ring N atom (359.6°) indicates sp2 The molecular structure features intramolecular C—H⋯S, C—H⋯F and C—H⋯O interactions. In the crystal, no significant intermolecular contacts were apparent.

A mixture of 5-(4-methylsulfanyl-benzylidenethiazolidine-2,4-dione (1 mmol), 2-bromo-1-cyclopropyl-2-(2-fluorophenyl)ethanone (1 mmol) and sodium bicarbonate (3 mmol) were taken in DMF and stirred for 6 h at 25–35 °C. After completion of the reaction as evident by TLC, (eluent: 7:3 / hexane:ethyl acetate) the mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine (20 ml) twice and then with water. The solvent was distilled off to obtain a viscous paste to which diisopropyl ether (5 volumes) was added. The resultant solid was filtered and washed with diisopropyl ether. The product was recrystallized from its methanol solution. Melting point: 414.5–415.9 Yield: 83.5%
H atoms were placed at calculated positions and allowed to ride on their carrier atoms with C—H = 0.93–0.98 Å. Uiso = 1.2Ueq(C) for CH2 and CH groups and Uiso = 1.5Ueq(C) for the CH3 group. The (0 1 1) reflection was probably affected by the beam-stop and was omitted from the refinement.

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. |

Thiazolidines are an important class of heteroaromatic compounds and have widespread applications from ranging from pharmaceuticals (Barreca et al., 2002) to materials (Botti et al., 1996). Thiazolidinediones (TZDs), which are known to sensitize tissues to insulin, have been developed and clinically used as anti-diabetic agents. They have been shown to reduce plasma glucose, lipid, and insulin levels, and are used for the treatment of type 2 diabetes (Day, 1999; Spiegelman, 1998). In view of this we have synthesized the title compound to study its crystal structure.
In the title compound, Fig. 1, the five-membered thiazolidine is nearly planar with a r.m.s. deviation of 0.003 Å. The 4-methyl sulfonyl benzylidine ring is nearly coplanar with the central thiazolidine ring as indicated by the dihedral angle of 8.35 (1)°. The 2-fluorobenzene and cyclopropyl rings make dihedral angles of 73.16 (17) and 70.2 (3)° with the thiazolidine ring, respectively. The sum of bond angles around N is 359.6° which confirms sp2 hybridization. In the cyclopropyl ring the mean C—C bond length is 1.504 (3) Å and the mean C—C—C bond angle is 60.0 (2)°; these are unexceptional. The molecular structure features intramolecular C—H···S, C—H···F C—H···O interactions (Table 1).
