Useful 1,2-dioxygenated dienes: syntheses and Diels-Alder reactions en route to substituted 2-naphthols and phenols

The alkenylation reaction of vinylene carbonate with vinyl triflates using a Pd catalyst provides an access to 1,2-dioxygenated dienes, which undergo a tandem DA cycloaddition/decarboxylative aromatization reaction to give 2-naphthols and phenols.
