title: An improved method for the synthesis of gamma-DDB.
abstract: A mild and efficient method for the synthesis gamma-DDB has been developed through anhydride-linker assisted intramolecular Ullmann reaction. Highly regioselective bromination of differentially protected gallate was realized by virtue of the introduction of NBS.
