In the title compound, C15H14BrNO3S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.034 (2) Å, and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene ring system and the morpholine ring is 86.32 (9)°. Intra­molecular C—H⋯S hydrogen bonds are observed. In the crystal, inversion-related C—H⋯S and C—H⋯O inter­actions generate R22(10) and R22(8) rings patterns, respectively. In addition, the crystal packing features ππ inter­actions between fused benzene rings [centroid–centroid distance = 3.7558 (12) Å].

Comment top

In recent years, much attention has been directed towards the synthesis of substituted coumarins owing to their tremendous application in various research fields including biological science and medicinal chemistry. Substituted coumarin derivatives are components of numerous natural products like warfarin, phenprocoumon, coumatetralyl, carbochromen, bromadialone, etc. These compounds also exhibit a wide band of biological activities including antibacterial, anti-HIV (Hesse & Kirsch, 2002), antiviral (Lee et al., 1998), anticoagulant (Jung et al., 2001), antioxidant (Melagraki et al., 2009) and anticancer activities (Jung et al.,(2004). Carbon–sulfur bond formation is a fundamental approach to bring sulfur into organic compounds, and this has received much attention due to its occurrence in many molecules that are of biological and pharmaceutical importance. The antibacterial and antifungal activities of dithiocarbamates were reported to arise by the reaction with HS-groups of the physiologically important enzymes by transferring the alkyl group of the dithioester to the HS-function of the enzyme (Schönenberger & Lippert, 1972). Organic dithiocarbamates, ubiquitously found in a variety of biologically active molecules (Dhooghe & De Kimpe, 2006), are of high importance in academia as well as in industry.

In view of the various physiological activities of coumarins and dithiocarbamates, our current studies are focused on the development of new routes for the synthesis of coumarins incorporating dithiocarbamate moieties.

The asymmetric unit of (6-bromo-2-oxo-2H-chromen-4-yl)methyl morpholine-4-carbodi thioate is shown in Fig. 1. The 2H-chromene ring systems is nearly planar, with a maximum deviation of 0.0337 (23) Å for the atom C16 and the morpholine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring and the morpholine ring is 86.32 (9) °. In the crystal structure, intermolecular C—H···O and intramolecular C–H···S hydrogen bonds are observed (Table 1) and inversion related C—H···S and C—H···O interactions generate R2 2(10) and R2 2(8) rings pattern respectively. In addition, the crystal packing is stabilized by ππ [Cg (3)– Cg(3);C8–C13] interactions between fused benzene rings [centroid- centroid distance = 3.7558 (12)].

Experimental top

All the chemicals used were of analytical reagent grade and were used directly without further purification. The title compound was synthesized according to the reported method (Devarajegowda et al., 2013). The compound is recrystallized by ethanol-chloroform mixture. Colourless needles of the title compound were grown from a mixed solution of Ethanol/Chloroform (V/V = 2/1) by slow evaporation at room temperature. Yield =72%, m.p.: 433–435 K

Refinement top

All H atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H and C—H = 0.97 Å for methylene H and refined using a riding model with Uiso(H) = 1.2Ueq(C) for aromatic and methylene H.

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.
