A novel, eco-friendly synthesis method for producing dithiocarbamates and rhodanines is presented, offering a greener alternative to conventional methods. This one-pot, three-component reaction involves the reaction of simple cyclic and acyclic aliphatic amines, carbon disulfide, and N-substituted maleimides under mild, ambient conditions. Importantly, the method proceeds without metal catalysts, bases, or additional additives, helping to minimize waste and reduce environmental impact. It delivers excellent efficiency, rapidly producing biologically relevant dithiocarbamate and rhodanine derivatives in high yields and with much shorter reaction times. Using commercially available starting materials further enhances accessibility and lowers costs, making this approach highly suitable for both research and industrial applications. This study highlights how green chemistry principles can enable sustainable and convenient routes for synthesizing important dithiocarbamate and rhodanine derivatives.
