Two biphenyllignans, 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 hindrance, stability, entropy change, and heat-of-formation values. The enantiomers of 1 and 2 were readily separated by HPLC on a chiral stationary
