Abstract
Hypervalent iodine compounds have proved to be very useful reagents to bring
about various oxidative transformations including (i) α-functionalization of carbonyl compounds,
(ii) oxidation of phenols, and (iii) oxidative rearrangement of ketones and α,β-
unsaturated ketones. These reactions find interesting applications in the development of
newer and convenient approaches for the synthesis of flavonoids. This review focuses on
the use of most common three hypervalent compounds, namely iodobenzene diacetate,
[hydroxy(tosyloxy)iodo]benzene, and [bis-trifluoroacetoxy(iodo)]benzene in the synthesis
of cis/trans-3-hydroxyflavanones, 3-hydroxyflavones (flavonols), flavones, isoflavones
and related compounds.
