Acetalization of prochiral 2,2',6,6'-biphenyltetrol with l-menthone proceeds in an enantiodifferentiating manner to give isomenthonide 5a of S-axial chirality as a major product, which can be used as a general intermediate for asymmetric synthesis of a series of (S)-6,6'-dialkoxy-2,2'-biphenyldiols 9a-f.
