An efficient and facile synthesis of a new class of novel chiral Salen Schiff base ligands has been developed via a stepwise approach. An important feature of these new Salen ligands is that they possess two different salicylaldehyde units, therefore, while steric factor or electronic factor can be fixed on one side, electronic or/and steric factors can be tuned from the other side with different substituents.
