Regioselective synthesis of methyl 2,3-dihydro-2-aryl benzofuran-3-carboxylates using thallium(III) nitrate

Article abstract of DOI:10.1080/00397919308009816

Flavanones (1a-d) undergo smooth ring contraction with thallium(III) nitrate in the presence of perchloric acid and trimethyl orthoformate resulting in the formation of methyl 2,3-dihydro-2-arylbenzofuran-3-carboxylates (2a-d) in good yields. The mechanism of this oxidation has also been discussed.
