The synthesis of novel chiral nitrogenligands and their precursors is described. They consist of an opticallyactive oxazoline bound to pyridine in the 2-position. In addition, another opticallyactive substituent is attached to the pyridine ring. The effect of the two independent stereogenic units in one ligand was studied in the Rh(I)-catalysed enantioselective hydrosilylation of acetophenone with
