6,7,4′-Trihydroxyisoflavanone, the main source of which is extracted from soybeans, has been found to have diverse significant bioactivities. A large-scale, cost-effective, and facile chemical synthesis of 6,7,4′-trihydroxyisoflavanone is presented herein. Its synthesis is characterized by three steps with an overall yield of 71% and a purity or more than 99.0%. This reaction can be scaled up to multikilogram quantities, providing a solid basis for its further bioactivity studies and drug development. With this same method, 6,7,3′,4′-tetrahydroxyisoflavanone, an analog of 6,7,4′-trihydroxyisoflavanone, also can be largely prepared, indicating this modified synthetic method is potentially available for large-scale synthesis of a broad range of multihydroxyl isoflavanones.

The palladium-catalyzed regioselective α-monoarylation of deoxybenzoins and α,α-diarylation of acetophenones provides general, efficient access to 1,2,2-triarylethanones. After a comprehensive search for suitable experimental conditions to optimize such transformations, both reactions are alternatively conducted by means of either commercially available polymer-anchored catalysts or a very simple homogeneous catalytic system, thus avoiding the use of complex ligands. In addition, the synthesis of deoxybenzoins employing polymer-supported fibrous palladium catalysts is reported for the first time, and the excellent catalyst recycling properties suggest applicability to industrial purposes.
