Oxidation of Flavonols using lead(IV) acetate in acidic methanol

Oxidation of Flavonols (1a-h) and 6-propionylflavonols (1i-j) to 2,3-dimethoxy-3-hydroxyflavanones (2a-h) and 2,3-dimethoxy-3-hydroxyflavanones (2i-j), respectively using lead(IV) acetate in methanol in presence of perchloric acid and the mechanism of this transformation has been described.
