In the title compound, C17H15NO2S, the two C atoms linking the S and carbonyl C atoms of the seven-membered thiazepine ring are disordered over two sites, with occupancies of 0.511 (4) and 0.489 (4); both disorder components adopt distorted twist-boat conformations. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds link inverted-related molecules into dimers, incorporating R12(6) and R22(8) ring motifs; the acceptor carbonyl O atom is bifurcated. These dimers are further linked by C—H⋯O hydrogen bonds, forming supramolecular tapes running along the a axis.

The title compound is used as an intermediate for the synthesis of dosulepin, which is an antidepressant of the tricyclic family. Dosulepin prevents reabsorbing of serotonin and noradrenaline in the brain, helps to prolong the mood lightening effect of any released noradrenaline and serotonin, thus relieving depression. Dibenzo[c,e]thiazepin derivatives exhibit chiroptical properties (Tomascovic et al., 2000). Dibenzo[b,e]thiazepin-5,5-dioxide derivatives possess antihistaminic and antiallergenic activities (Rajsner et al., 1971). Benzene thiazepin derivatives are identified as a type of effective antihistaminic compounds (Metys et al., 1965). In view of this biological importance, the
of the title compound has been carried out and the results are presented here.Fig. 1 shows a displacement ellipsoid plot of (I), with the atom numbering scheme. The geometric parameters of the title molecule agree well with those reported for similar structures (Selvakumar et al.., 2012; Lakshmanan et al., 2012). The sum of angles at N1 atom of the thiazepin ring (359.9°) is in accordance with sp2
Both the major and minor conformers of the disorderd thiazepine ring adopt distorted twist-boat conformations.In the crystal, intermolecular bifurcated acceptor N1—H1···O1i and C6—H6···O1i (Table 1) hydrogen bonds link inverted-related molecules into dimers, incorporating R12(6) and R22(8) ring motifs. These dimers are further linked by C1B—H1C···O1ii (Table 1) hydrogen bonds forming supramolecular tapes running along the a axis (Fig. 2).
A mixture of (Z)-methyl 2-(bromomethyl)-3-(4-methoxyphenyl)acrylate (2 mmol) and o-aminothiophenol (2 mmol) in the presence of potassium tert-butoxide (4.8 mmol) in dry THF (10 ml) was stirred at room temperature for 1 h. After the completion of the reaction as indicated by TLC, the reaction mixture was concentrated and the resulting crude mass was diluted with water (20 ml) and extracted with ethyl acetate (3 x 20 ml). The organic layer was washed with brine (2 x 20 ml) and dried over anhydrous sodium sulfate. It was then concentrated to successfully provide the crude final product ((Z)-3-(4-methoxybenzylidene)-2,3-dihydrobenzo[b][1,4] thiazepin-4(5H)-one). This was purified by
on silica gel with ethylacetate/hexane 1:19 as to afford the title compound in good yield (47 %). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of its ethylacetate solution at room temperature.Atoms C1 and C9 of the thiazepine ring are disordered over two positions (C1A/C1B and C9A/C9B) with refined occupancies of 0.511 (4) and 0.489 (4). The corresponding bond distances involving the disorderd atoms were restrained to be equal. H atoms were positioned geometrically, (C—H = 0.93–0.97 Å and N—H = 0.86 Å) constrained to ride on their parent atom, with Uiso(H)=1.5Ueq for methyl H atoms and 1.2Ueq(C) for other H atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |
