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.

The oxidative coupling between benzaldehyde derivatives and phenylacetylene catalyzed by rhodium complexes via C-H bond activation

This paper reports the use of rhodium (Rh) catalysts for the oxidative coupling reaction between phenylacetylene and benzaldehyde derivatives via C-H bond activation. These reactions were catalyzed by Rh(l-amino acid)(cod) (the l-amino acid is l-phenylala

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.
