The synthesis of chiral 2,2'-diselenobisbenzoates (3) from 2-aminobenzoic acid and chiral alcohols was elaborated. Similar method was applied for the preparation of chiral 2,2'-diselenobisbenzenesulfonates (4) from 2-aminobenzenesulfonic acid. Ester 3a was an efficient catalyst for chemoselective hydrogen peroxide oxidation of sulfides into sulfoxides but no stereoselectivity of the reaction was observed.
The synthesis of 2,2_-diselenobisbenzamides and 4,4_-diselenobisbutyramides with sulfamoyl functions, two new groups of potential antiviral agents and cytokine inducers, based on the acylation of the 4-aminobenzenosulfonamides with corresponding chlorocarbonylaryl or chlorocarbonylalkyl diselenides, has been elaborated. In a similar way dithiobenzamide and diphenic acid bisbenzamide were obtained from dithio-2,2-bisbenzoic acid and diphenic acid dichlorides respectively.
