Oxidation of Flavonols via Oxythallation Using Thallium(III) Acetate (TTA) and Thallium(III) Nitrate (TIN) in Methanol

Oxidation of flavonols (1a-f), α-naphthoflavonol (3) and 6-propionylflavonols (5a-b) to 2,3-dimethoxy-3-hydroxyflavanones (2a-f), 2,3-dimethoxy-3-hydroxy-α-naphthoflavanone (4) and 2,3-dimethoxy-3-hydroxy-6-propionylfavanones (6a-b), respectively, using thallium(III) acetate and thallium(III) nitrate in methanol is described.A mechanistic Scheme of these transformations has also been proposed.
