Chiral vanadium complex-catalyzed oxidative coupling of arenols

This report describes the recent advances in the development of chiral vanadium complex-catalyzed oxidative couplings of phenols such as polycyclic phenols, hydroxycarbazoles, resorcinol, and sesamol derivatives. Catalysts containing a vanadium metal and multidentate ligand prepared from salicylaldehydes and chiral amino acids provide chemists with a powerful tool for the efficient synthesis of optically active, axially chiral compounds, which can be readily transformed into biologically active compounds and chiral ligands.
