摘要

Abstract Application of the Suzuki cross-coupling reaction for efficient synthesis of diverse substituted biaryl-chromen-4-ones using an optimized palladium (0) catalyst system is reported. The coupling of arylboronic acids with the resin-bound bromoflavanones which were prepared by organoselenium-induced regioselective intramolecular cyclization of bromo-2-hydroxylchalcones proceeded smoothly. Biaryl-chromen-4-ones were ...
