A new, simple, one-step synthetic route to carbamo(dithioperoxo)thioates from commercially available
starting materials is described. The key step of this new synthetic approach involves the tetrabromomethane-
promoted reaction between secondary amines, carbon disulfide and alkyl thiols under basic
conditions at room temperature. New compounds from this series selected for anticancer screening
showed selective sub-micromolar activity within BCA2-expressing human breast cancer cell lines.
