Arylation of ortho-Hydroxyarylenaminones by Sulfonium Salts and Arenesulfonyl Chlorides: An Access to Isoflavones

Herein we disclose three new methods for the straightforward and efficient synthesis of 3-arylchromones following the arylation of ortho-hydroxyarylenaminones by vast diversities of bench-stable and easy-to-use sulfonium salts and arenesulfonyl chlorides.

Pd-Catalyzed efficient cross-couplings of 3-iodochromones with triarylbismuths as substoichiometric multicoupling organometallic nucleophiles

An efficient cross-coupling of 3-iodochromones with triarylbismuths under catalytic palladium conditions is reported. Triarylbismuths were employed as substoichiometric multicoupling nucleophiles for the synthesis of a variety of substituted isoflavones.

Oxidation of Flavanones using Thallium(III) Salts: A New Route for the Synthesis of Flavones and Isoflavones

When treated with thallium(III) acetate in acetic acid or acetonitrile, flavanones undergo facile dehydrogenation to afford flavones whereas, upon treatment with thallium(III) toluene-p-sulfonate or thallium(III) nitrate in propionitrile or acetonitrile, respectively, they undergo oxidative 2,3-aryl migration to give isoflavones in high yield.
