Additional recommended knowledge
2-Pyrone is used in organic synthesis as a building block for more complex chemical structures because it may participate in a variety of cycloaddition reactions to form bicyclic lactones. For example, it readily undergoes Diels-Alder reactions with alkynes producing, upon loss of carbon dioxide, substituted benzenes.
2-Pyrone also forms the the core structure of a variety of natural organic compounds. For example, the coumarins are an important class of compounds which are benzo-fused derivatives of 2-pyrone.
