摘要

Abstract The highly functionalized unsymmetrical biphenyls having electron-donating and/or electron-withdrawing substituents on the ortho positions were effectively synthesized based on the intramolecular Ullmann coupling reaction directed by salicyl alcohol as a template, followed by selective cleavage of the two ester bonds of 5.
