Synthesis and Applications of Binaphthylic C2-Symmetry Derivatives as Chiral Auxiliaries in Enantioselective Reactions

In this review, after a general introduction devoted to show the importance of the role played by C 2-symmetry chiral auxiliaries to provide high levels of stereoselection, a complete survey of the preparation and use of optically active 1,1' -binaphthyl derivatives as chiral auxiliaries in asymmetric synthesis is attempted.
