The synthesis of several novel chiral phosphoramidite ligands (L1-L8) with C-2 symmetric, pseudo C-2 symmetric secondary amines and chiral Bronsted acids 1a,b has been achieved. These chiral auxiliaries were obtained from commercially available D-mannitol, and secondary amines in moderate to excellent yields. Excellent diastereoselectivites of ten chiral auxiliaries were obtained. The chiral phosphoramidite ligands and chiral Bronsted acids were fully characterized by spectroscopic methods.
