Abstract

Selective oxidation of 6-propionyl flavonols (1a-d) and 6-propionyl-2-hetarylchromonols (1e-f) to 2,3-dimethoxy-3-hydroxy-6-propionylf lavanones (2a-d) and 2,3-dimethoxy-3-hydroxy-6-propiony1-2-hetarylchromanones (2e-f), respectively, using [bis(trifluoroacetoxy)iodo]benzene(BTFAIB), [hydroxy(tosyloxy)-iodo] benzene (HTIB), iodobenzene diacetate (IBD) and iodosylbenzene (IB) in methanol has been described.
