摘要：

Oxadation of flavonols (la-f) α-nanhthoftavonol (3) and 6-propionylflavonols (5a-b) to 2,3-dimethoxy-3-hydroxy-flavanones (2a-f), 2,3-dimethoxy-3-hydroxy- a-naphthoflavanone (4.) and 2,3-dimethoxy-3-hydroxy-6-propionylflavanones (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. © 1990, Taylor & Francis Group, LLC. All rights reserved.
