The tandem "pincer" Diels-Alder reaction, consisting of two consecutive [4 + 2] cycloadditions between two dienes and an acetylenic bis-dienophile, has been applied toward the rapid construction of bridged polyoxacyclic ring systems when furan derivatives are used as the diene components. The study has demonstrated the stereoselectivity (exo-exo adduct), the chemoselectivity ("pincer" vs "domino")
FeCl3-catalyzed convenient synthesis of 3-hydroxyphthalates has been achieved by a Diels–Alderreaction of furans with dimethylacetylenedicarboxylate, followed by ring-opening aromatization reaction of the Diels–Alder adducts, 7-oxabicyclo[2.2.1]hepta-2,5-diene derivatives. In addition, 7-azabicyclo[2.2.1]hepta-2,5-diene derivative, derived from N-Boc-pyrrole and dimethylacetylenedicarboxylate, also converted
