Palladium-catalyzed direct arylation of 4-chromanones: Selective synthesis of racemic isoflavanones and 3,3-diaryl-4-chromanones

For the first time, the synthesis of racemic isoflavanones has been achieved in satisfactory to good yields and with high selectivity by Pd-catalyzed direct C-3 arylation of 3-unsubstituted 4-chromanones with aryl bromides with the aid of a Pd2(dba)3/tBu 3PHBF4 catalyst system in the presence of KHCO3 as the base in a dioxane/water mixture (4:1). This catalyst system has also been employed in an unprecedented synthesis of 3,3-diaryl-4-chromanones through direct arylation of 4-chromanones in water.
