A novel and efficient copper-catalyzed one-pot procedure for the synthesis of 3-N-substituted 1,4,2-benzodithiazine 1,1-dioxide derivatives from 2-halobenzenesulfonamides, amines and CS2 is described. The reaction proceeds through Ullmann-type S-arylation, intramolecular addition of NH2 with C[dbnd]S and dehydrosulfide, which provides a new and useful strategy for construction of cyclic aromatic sulfonamides.

This protocol describes a novel, mild and convenient route to afford 2-aminobenzoxazoles in high yields, and represents a significant advance towards an environmentally friendly strategy. Aliphatic amines are made to react with carbon disulfide to provide intermediate dithiocarbamates (DTC), which in the presence of 2-aminophenol, subsequently undergo successive intermolecular nucleophilic attack and desulfurization to produce 2-aminobenzoxazoles within 3 h.
Thiocarbamoylation of amine-containing compounds 4. Reactions of tetramethylthiuram disulfide with aliphatic amines
Van Boi, Luu
, p. 2294 - 2298 (2007/10/03)
Thiocarbamoylation of primary and secondary aliphatic amines with tetramethylthiuram disulfide in various solvents at different temperatures was studied. At 110 °C, the reactions with primary amines afforded mixed N,N-dimethyl-N′-alkyl(cycloalkyl)thiourea
