2‐thioxoimidazolidine‐1‐carbothioamides, and 2‐thioxotetrahydropyrimidine‐1(2H)‐carbothioamides were synthesized via conventional thermal or microwave‐assisted reaction of isatylidenemalononitrile with N,N″‐1,ω‐alkanediyl‐bis‐[N′‐organylthiourea] derivatives. Rationale for these conversations involving the nucleophilic addition on the dicyanomethylene carbon atom and intramolecular heterocyclization of the title
