Dong, Wei; Ge, Zemei; Wang, Xin; Li, Ridong; Li, Runtao published the artcile< Cu-mediated one-pot three-component synthesis of 3-N-substituted 1,4,2-benzodithiazine 1,1-dioxide derivatives>, HPLC of Formula: 3731-53-1, the main research area is halobenzenesulfonamide amine carbon disulfide copper catalyst three component reaction; amino benzodithiazine dioxide preparation.
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 was described. The reaction proceeded through Ullmann-type S-arylation, intramol. addition of NH2 with C=S and dehydrosulfide, which provided a new and useful strategy for construction of cyclic aromatic sulfonamides.
