2Pyranones
2-Pyranones, also known as alpha-pyrones, are a class of organic compounds that are characterized by a six-membered heterocyclic ring containing one oxygen atom and a carbonyl group in the alpha position relative to the oxygen. The basic structure is a pyran ring with a double bond at the 2-position and a ketone group at the 2-position. This structural feature leads to conjugation within the ring system.
These compounds can exist in tautomeric forms, with the keto form (2-pyranone) and the enol form (2-hydroxypyran)
Naturally occurring 2-pyranones are produced by a variety of organisms, including plants, fungi, and bacteria. They
Synthetic routes to 2-pyranones often involve cyclization reactions. Common methods include the cyclization of dicarbonyl compounds
