(Received 3 April 2009; accepted 6 April 2009; online 8 April 2009)

In the crystal structure of the title compound, C₁₆H₁₃NO₃S, the benzisothiazole group is almost planar (r.m.s. deviation for all non-H atoms excluding the two O atoms bonded to S = 0.009 Å). The dihedral angle between the fused ring and the terminal ring is 13.8 (1)°. In the crystal, molecules are linked through intermolecular C—H⋯O contacts forming a chain of molecules along b.

Comment top

Benzisothiazolone-1,1-dioxide and its various derivatives are well known as biologically active compounds e.g., saccharin has been identified as an important molecular component in various classes of 5-HTla antagonists, analgesics and human mast cell tryptase inhibitors (Liang et al., 2006). Few of its derivatives are considered to be the most potent orally active human leucocyte elastase (HLE) inhibitors for the treatment ofchronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), cystic fibrosis, asthma and other inflammatory diseases (Kapui et al., 2003). Its N-alkyl derivatives have been successfully transformed to non-steroidal anti-inflammatory drugs e.g., piroxicam (Zia-ur-Rehman et al., 2006).

In continuation to our research on the synthesis of 1,2-benzothiazine 1,1-dioxide derivatives (Zia-ur-Rehman et al., 2009; Zia-ur-Rehman et al., 2006), we have in addtion, worked on the synthesis of benzisothiazole derivatives (Siddiqui et al., 2006; Siddiqui et al., 2008). Herein, crystal structure of the title compound (I) is described. The benzisothiazole moiety is exactly planar.The molecular dimensions are in accord with the corresponding dimensions reported in similar structures (Siddiqui et al., 2007a-c). Each molecule is linked to its adjacent one through C—H···O contacts forming a chain of molecules along b.

Experimental top

A mixture of 2,3-dihydro-1,2-benzisothiazol-3-one-1,1-dioxide (1.83 g, 10.0 mmoles), dimethyl formamide (5.0 ml) and cinnamyl chloride (1.67 g, 10.0 mmoles) was stirred for a period of three hours at 90°C. Contents were cooled to room temperature; poured over crushed ice to get white coloured precipitates which were filtered, washed and dried. Crystallization of the white precipitates (in methanol) afforded suitable crystals for X-ray studies after recrystalization in methanol.

Special details top

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.
