(Received 4 November 2013; accepted 15 November 2013; online 23 November 2013)

The title compound, C12H9BrN2OS2, was obtained by reacting 6-bromo­benzo[d]thia­zole-2-carbo­nitrile in iso-propanol with ethyl 2-mercapto-2-methyl­propano­ate at reflux temperature for several hours. The resulting di­methyl­oxyluciferin derivative shows partial double-bond character of the carbon–carbon bond between the two heterocyclic moieties [C—C = 1.461 (3) Å]. This double bond restricts rotation around this C—C axis, therefore leading to an almost planar mol­ecular structure [N—C—C—S torsion angle = 9.7 (3)°]. The five-membered thiazoline ring is not completely planar as a result of the bulky S atom [C—S—C—C torsion angle = 5.17 (12)°].

Comment top

Heterocycles are widely used in nature for a great variety of purposes. One of the most interesting ones is bioluminescence which is defined as the chemically stimulated emission of light by living organisms. One prominent example of a bioluminescent organism is the firefly (Photinus pyralis), which employs the benzothiazole containing Luciferin for light emission (White et al., 1961). One known inhibitor for this Luciferin-Luciferase reaction is the structurally close related dimethyloxyluciferin (Meroni et al., 2009). This compound also shows a bright red fluorescence in the visible spectrum in the deprotonated state (Branchini et al., 2002). Therefore investigations where conducted in our group focusing on modifications of the benzo[d]thiazol moiety of dimethyloxyluciferin (Würfel, 2012).

The title compound was synthesized by condensation of 6-bromobenzo[d]thiazole-2-carbonitrile with 2-mercapto-2-methylpropanoate. The Br—C bond length of 1.898 (2) Å (Br1—C4) is typical for a bromine atom bonded to an aromatic ring. The substituted benzo[d]-thiazol moiety builds up a planar structure, whereas the thiazoline ring is not exactly planar because of one sp3 carbon atom (C10). Since sp3 carbon atoms prefer smaller bond angles than sp2 carbons, C10 is pushed out of the thiazoline plane. The C—C bond, connecting the heterocyclic moieties shows a partial double bond character (C1—C8, 1.461 (3) Å). The sulfur atoms S1 and S2 are arranged trans in the crystal, thus providing the maximal distance from each other (4.3686 (7) Å). Despite of the double bond character of C1—C8 the heterocyclic moieties are not exactly coplanar with respect to each other. The torsion angles N1—C1—C8—S2 show a deviation of -9.7 (3)°.

Experimental top

All chemicals were synthesized according to given literature or purchased from commercial sources. All solvents were purified and dried according to Armarego & Chai (2009). 3.46 g (14.5 mmol) 6-bromobenzo[d]thiazole-2-carbonitrile, 2.5 ml (approx. 17.4 mmol) ethyl 2-mercapto-2-methylpropanoate and 4.8 ml (34.8 mmol) triethylamine were refluxed in 20 ml of iso-propanol for 6 h. The product was recrystallized from ethanol yielding 70% (3.46 g, 10.1 mmol) pale yellow crystals. 6-Bromobenzo[d]thiazole-2-carbonitrile was prepared analog to Würfel et al. (2012). Ethyl 2-mercapto-2-methylpropanoate was prepared according to Bardsley et al. (2009a,b). Yellow single crystals of the title compound were obtained by dissolving the compound in ethanol at reflux temperature and after cooling to r. t. the closed vessel was left alone for several days. Elemental analysis calculated for C12H9BrN2OS2: C 42.24, H 2.66, Br 23.42, N 8.21, S 18.79; found: C 42.12, H 2.63, Br 23.51, N 8.11, S 19.00.

Refinement top

All hydrogen atoms were set to idealized positions and were refined with Uiso(H) = 1.2 Ueq(C) (1.5 for methyl groups). Methyl groups were allowed to rotate but not to tip.

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.
