chromanone

Chromanone is a chemical compound with the molecular formula C9H8O2. It is a heterocyclic organic molecule that features a benzene ring fused to a dihydropyranone ring. Specifically, it is a derivative of chromane where a carbonyl group is present at the 4-position of the dihydropyran ring. The core structure of chromanone is sometimes referred to as a benzodihydropyran-4-one.

Chromanone and its derivatives are found in various natural products and have been explored for their biological activities. The chromanone scaffold is a common structural motif in many flavonoids and related compounds, which are known for their antioxidant and other pharmacological properties. Synthetically, chromanone can be prepared through several routes, often involving cyclization reactions. Its chemical reactivity is influenced by the presence of the carbonyl group and the aromatic ring, allowing for further functionalization and derivatization. Research into chromanone derivatives continues to investigate their potential applications in medicinal chemistry and materials science.
