The biaryl substructure is a central building block in a very large number of natural products, such as polyketides, terpenes, lignanes, coumarins, flavonoids, tannins, and many alkaloids. 1 Homochiral 1,1′-binaphthalene derivatives have successfully been utilized as chiral inducers for highly stereoselective reactions because of their axial dissymmetry and molecular flexibility. 2 Therefore, it is essential to establish simple and convenient methods for the ...
