The intermolecular reductive cyclization of o-nitrobenzene-sulfonamides with aliphatic ketones induced by TiCl4/Sm system was studied and a series of 3,3-disubstituted-3,4-dihydro-(2H)-1,2,4-benzothiadiazine-1,1-dioxides were synthesized in moderate to high yields under mild and neutral conditions.
