Synthesis of Substituted Thiophene-1,1-Dioxides and their Ring-Opening Reactions with w-Unsaturated Secondary Amines; a Synthetic Route to Azatrienes.
The scope and limitations of the ring-opening of thiophene dioxides upon reaction with cyclic secondary amines, leading to dialkylaminomethyl substituted halobutadienes has been further studied. Using ω-unsaturated acyclic secondary amines trienes could be prepared by this methodology.
