In the title compound, C24H17NO4S, the phenyl ring makes a dihedral angle of 88.12 (5)° with the carbazole unit. The molecular structure is stabilized by weak intramolecular C—H⋯O interactions and the crystal packing exhibits weak intermolecular C—H⋯O and C—H⋯π interactions. Two C atoms of the 2,3-dihydro-1,4-dioxine fragment are disordered over two positions with site-occupancy factors of 0.718 (11) and 0.282 (11).

To a solution of diethyl-2-((2-(bromomethyl)-1-(phenylsulfonyl) -1H-indol-3-yl) methylene)malonate (0.5 g, 0.96 mmol) in dry DCE (15 ml), anhydrous ZnBr2 (0.43 g, 1.90 mmol) and 1,4-benzodioxane (0.14 ml, 1.17 mmol) were added. It was stirred at room temperature for 2 h and then refluxed for 0.5 h under N2 atmosphere. The solvent was removed and the residue was quenched with ice-water (50 ml) containing 1 ml of conc.HCl, extracted with chloroform (2 x 10 ml) and dried (Na2SO4). Removal of solvent followed by flash column chromatographic purification (n-hexane/ethyl acetate 99:1) led to the isolation of colourless crystal of the title compound.
H atoms were positioned geometrically and refined using riding model with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic C—H and C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2. The site occupancy factors of disordered C12 and C13 atoms refined at 0.718 (11) for major position and 0.282 (11) for minor position. The anisotropic displacement parameters of C3 and C4 were restrained with DELU in the final cycles of refinement.
Carbazole derivatives possess antioxidative (Tachibana et al., 2001) and anti-inflammatory and antimutagenic (Ramsewak et al., 1999) activities. The geometric parameters of the molecule (Fig. 1) agree well with the reported similar structures (Chakkaravarthi et al. 2008a,b).
The phenyl ring makes the dihedral angle of 88.12 (5)° with the carbazole ring system. The sum of the bond angles around N1 [357.29 (11)°] indicates that N1 atom is sp2 hybridized. The molecular structure is stabilized by weak intramolecular C—H···O interactions and the crystal packing exhibits weak intermolecular C—H···O (Fig. 2) and C—H···π interactions[C12—H12A···Cg1(2 - x, 1/2 + y, 3/2 - z) distance of 3.670 (5) Å; C12—H12B···Cg7 (2 - x, 1/2 + y, 3/2 - z) distance of 3.411 (5) Å; C13—H13A···Cg5 (1/2 + x, y, 3/2 - z) distance of 3.680 (5) Å; C20—H20··· Cg4 (x, 1/2 - y, 1/2 + z) distance of 3.689 (2) Å; C12A—H12C···Cg5 (1/2 + x, y, 3/2 - z) distance of 3.446 (14) Å; C12A—H12D···Cg7 (2 - x, 1/2 + y, 3/2 - z) distance of 3.585 (14) Å; C13A—H13D···Cg1 (2 - x, 1/2 + y, 3/2 - z) distance of 3.585 (14) Å; Cg1,Cg4,Cg5 and Cg7 are the centroids of the rings N1/C7/C18/C19/C24, C1—C6, C/7/C8/C9/C16/C17/C18 and C19—C24, respectively].

Carbazole derivatives possess antioxidative (Tachibana et al., 2001) and anti-inflammatory and antimutagenic (Ramsewak et al., 1999) activities. The geometric parameters of the molecule (Fig. 1) agree well with the reported similar structures (Chakkaravarthi et al. 2008a,b).
The phenyl ring makes the dihedral angle of 88.12 (5)° with the carbazole ring system. The sum of the bond angles around N1 [357.29 (11)°] indicates that N1 atom is sp2 hybridized. The molecular structure is stabilized by weak intramolecular C—H···O interactions and the crystal packing exhibits weak intermolecular C—H···O (Fig. 2) and C—H···π interactions[C12—H12A···Cg1(2 - x, 1/2 + y, 3/2 - z) distance of 3.670 (5) Å; C12—H12B···Cg7 (2 - x, 1/2 + y, 3/2 - z) distance of 3.411 (5) Å; C13—H13A···Cg5 (1/2 + x, y, 3/2 - z) distance of 3.680 (5) Å; C20—H20··· Cg4 (x, 1/2 - y, 1/2 + z) distance of 3.689 (2) Å; C12A—H12C···Cg5 (1/2 + x, y, 3/2 - z) distance of 3.446 (14) Å; C12A—H12D···Cg7 (2 - x, 1/2 + y, 3/2 - z) distance of 3.585 (14) Å; C13A—H13D···Cg1 (2 - x, 1/2 + y, 3/2 - z) distance of 3.585 (14) Å; Cg1,Cg4,Cg5 and Cg7 are the centroids of the rings N1/C7/C18/C19/C24, C1—C6, C/7/C8/C9/C16/C17/C18 and C19—C24, respectively].
