## Abstract Two biphenyl lignans, __α__‐ and __β__‐DDB (**1** and **2**, respectively) were efficiently synthesized without contamination by other regio‐isomers. The different yields of the __Ullmann__ coupling reactions for the synthesis of **1** and **2** were rationalized by calculating steric h
