Abstract
Oxidation of flavonols by potassium superoxide (KO 2) in heterogeneous aprotic media yields acids and aldehydes by opening of ring C, if the latter contains an ethylenic double bond substituted by an OH group. A mechanism is proposed for this reaction. Other flavonoids like flavones, flavans and flavanones induce only the disproportionation of superoxide anion, without undergoing further oxidation; these flavonoids are therefore anti-oxidants of particular interest.
