The development of a new method for the synthesis of 1,1‐dioxido‐1,2‐benzisothiazoline‐3‐acetic acid by a domino process is reported whereby a classical Heck reaction is coupled to an intramolecular aza‐Michael reaction. Ultimately, this method has been expanded to a one‐pot, sequential three‐component protocol to generate diverse benzofused γ‐sultams from a range of commercially available α‐bromobenzenesulfonyl chlorides, amines and Michael acceptors.
