A general process for the efficient synthesis of vinylsulfones has been developed using commercially available sulfinic acid sodium salts and dibromides. A variety of phenyl and methyl vinylsulfones have been formed in good yields, in the absence of any catalyst.
The cycloaddition reaction of nitrones to unsaturated methylsulfones and substituted crotonic esters gives a sole product or a mixture of tri- or tetra-substituted isoxazolidines, such that with disubstituted dipolarophiles the regiochemistry is dependent upon the nitrone and the vicinal electron-withdrawing group (CN or CO2Me) but with trisubstituted olefins, regiospecific cycloadditions are observed

The present invention is directed to a pharmaceutical composition comprising a pharmaceutically acceptable carrier and an ω-(methanesulfonyl)alkenylnitrile compound, or a pharmaceutically acceptable salt thereof. The present invention is also directed to a method for treating inflammation, inflammatory-related disorders, or pain, by orally administering an ω-(methanesulfonyl)alkenylnitrile compound or a pharmaceutically acceptable salt or solvate thereof to a subject in need thereof.
