molecular arrangement where a chiral fragment derived from menthone or camphor transfers its central chirality to a 2,2'-biphenol residue, inducing an axialchirality, is reported. The menthol or isoborneol groups are attached at the two benzylic positions at 3,3' in order to maximize efficiency in practical applications. A reliable and high-yielding procedure for the synthesis of such C(2)-symmetric molecules
