Facile synthesis of 2,2′-dichalcogenobis (N-alkyl/aryl benzenesulfonamides) from N-substituted benzenesulfonamides and the emergence of 2-alkyl 1,3,2-benzothiaselenazole 1,1 dioxides. Ebselen analogues
摘要:
A one pot synthesis of 2-2'-diselenobis/ditellurobis(N-alkyl/aryl benzenesulfonamides) 4a-h from N-alkyl/aryl benzenesulfonamides is elaborated. The first cyclization of 2-2'-diselenobis (N-methyl benzenesulfonamide) 4a into 2- methyl-1,3,2-benzothiaselenazole 1,1 dioxide (5a)(1a) using 3-chloroperoxybenzoic acid is described. Compounds 4a-h and 5a and d act as a new class of biologically active(1b) compounds. (C) 1997 Elsevier Science Ltd.

Synthesis of bis(2-chlorosulfonylphenyl) diselenide (11) from 2-aminobenzenesulfonic acid was elaborated. It was shown that (11) is a good starting material for synthesis of the organoselenium sulfonamides, such as bis(2-sulfamoylphenyl) diselenides (3)and benz-2,3-azaselenathiophene I,l-dioxides (4), being potential immunostimulants and oxidation catalysts.
