ChemInform Abstract
The asymmetric desymmetrization of prochiral 2,2′,6,6′-biphenyltetrol is effectively achieved by acetalization with l-menthone. The resulting isomenthonide (I) of S-axial chirality allows the preparation of a variety of 6,6′-dialkoxy- and aromatic substituted derivatives (II) and (III).
