Comment

Diarylmethane motifs are found in some C-aryl glucoside anti-diabetic agents prototypes. Gaining understanding of these motifs is of interest to the pharmaceutical industry (Xu et al., 2009). The asymmetric unit contains one molecule of the title compound. There are no classic hydrogen bonds in the structure. A weak C-H···O interaction pairs the molecules in a head-to-tail fashion. Crystal packing is controlled by van der Waals forces and π–π stacking interactions between both rings.

The separate π–π interactions, rings C3-C8 and C10-C15, are almost normal to each other at 87.88 (4)° and stabilize the structure. The rings are configured in a parallel-displaced configuration, the distance from closest contacts (C5-C15) is 3.599 (2) Å and measured from centroid-to-centroid these rings are separated by 4.8391 (1) Å.

The dithiane ring is in the expected chair conformation with a slight twisting in reference to the benzene ring, to avoid steric repulsion. The saturated ring exhibits a slight outward distortion from the C—S, due to the longer C—S bond. From the dithiane ring the benzene ring is in the expected equatorial position. These features are all common to dithiane crystal structures (Fun et al., 2009). Viewed down the c axis, the dithiane rings inter-leave (Figure 2).

Experimental

A synthesis of compound 1 is described on Fig. 3. Friedel Craft acylation of ethoxy benzene with 2-chloro-5-methyl benzoyl chloride in dichloromethane in presence of aluminum trichloride produced intermediate 2 in 30% yield. Radical bromination of 2 under classical conditions (AIBN, NBS, CCl4) gave 3 (52% yield) which was subsequently treated with triethylsilane and boron trifluoride diethyl etherate to provide 4 in 81% yield. Nucleophilic displacement with sodium acetate followed by deacetylation (NaOMe/MeOH) led to intermediate 5 in 73% yield over 2 steps. Parikh-Doering oxidation produced the desired aldehyde intermediate 6 in 85% yield. Alternatively, Kornblum oxidation of 4 using 2,4,6-collidine in presence of dimethylsulfoxide gave 6 in 51% yield. Treatment of 6 with 1,3-propanedithiol in the presence of boron trifluoride diethyl etherate cleanly produced dithiane 1 in 74% yield. 1 was dissolved in ethyl acetate and allowed to evaporate over twelve hours to form X-ray diffraction quality crystals. Further details of the synthesis are included in the Experimental Special Details section.

Special details

Experimental. (2-Chloro-5-methyl-phenyl)-(4-ethoxy-phenyl)-methanone (2):To a solution of 2-chloro-5-methyl-benzoic acid (1.0 g, 5.86 mmol) in dichloromethane (12 ml) was added at room temperature (~23°C) oxalyl chloride (0.54 ml, 6.2 mmol) followed by the dropwise addition of N,N-dimethylformamide (0.1 ml). The resulting solution was allowed to stir overnight at room temperature before being concentrated under reduced pressure to produce crude 2-chloro-5-methylbenzoyl chloride which was used in the next step without further purification. The crude 2-chloro-5-methylbenzoyl chloride (1.15 g, 5.86 mmol) and ethoxybenzene (0.75 g, 6.14 mmol) were dissolved in 10 ml of dichloromethane and the resulting solution was cooled to 0°C. Aluminum trichloride (0.85 g, 6.38 mmol) was added and the reaction mixture was allowed to stir at 0°C for 4 hours before being allowed to warm to room temperature overnight (~16 hours). The reaction was quenched by pouring the solution over ice. The mixture was diluted with water and extracted three times with dichloromethane. The combined organic layers were successively washed with aqueous 1 N hydrochloric acid solution, aqueous 1 N sodium hydroxide solution, brine, dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude material was chromatographed using an ISCO automated chromatography unit (40 g silica gel column) and eluting with a gradient of 0-40% ethyl acetate in heptane yielding 650 mg (30% yield) of an oil that solidified upon standing.

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 takeninto account individually in the estimation of esds in distances, anglesand torsion angles; correlations between esds in cell parameters are onlyused 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 > 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.
