Diels-Alder and reverse Diels-Alder reactions

Pyrones can be used as routes to aromatic rings, however, they are rather unstable and barely aromatic. They can react with alkynes via a Diels-Alder reaction, followed by a reverse Diels-Alder reaction, involving the loss of carbon dioxide, to produce benzene derivatives.
