## Abstract __N__‐Sulfonylalkylamines 2a, b react with ynamines 3 to give primarily 2__H__‐1,2‐thiazete 1,1‐dioxides 4. But, except for the 4‐triphenylsilyl species 4a, b, these products are unstable and undergo electrocyclic ring opening to very reactive amidinosulfenes 5, which are transformed in
