Flavanone

Flavanone skeleton with locants

The flavanones are a type of flavonoids. They are generally glycosylated by a disaccharide at position seven to give flavanone glycosides.

List of flavanones

The enzyme chalcone isomerase uses a chalcone-like compound to produce a flavanone.
Flavanone 4-reductase is an enzyme that uses (2S)-flavan-4-ol and NADP⁺ to produce (2S)-flavanone, NADPH, and H⁺.

Numerous methods exist for the enantioselective chemical and biochemical synthesis of flavanones and related compounds.^[1]
