The title compound 2 is a rigid molecule with two potential 1,3‐diene units . It was synthesized in three steps from the diester 1 . The successive opening of the four‐membered rings of 2 enables the construction of linear annelated ring systems and band structures; for example, the reaction with dimethyl acetylenedicarboxylate leads to the tricycle 3 .
