Synthesis of C2-Symmetric Acyclic 1,2-Diaryl-Substituted 1,2-Diamines

Synthesis of C2-Symmetric Acyclic 1,2-Diaryl-Substituted 1,2-Diamines 

The reductive couphng of the chiral planar di(imine) 42, prepared from the corresponding chiral (il)-dialdehyde, in turn available as a single enantiomer by standard reactions, can lead to four stereoisomers. The use of
