The first regiospecific synthesis of the 2,3‐dihydrothieno[2,3‐ b ]thiophene ring system was achieved using an intramolecular Michael addition in the key cyclization step. This strategy represents a novel and potentially general method for dihydrothiophene and dihydrothiophene S,S ‐dioxide annellation.
