stereocenters, it was demonstrated that the absolute configuration of the product alcohol was determined by the configuration of the amino acidpart of the ligand. Employing ligands based on L-amino acids generated S-configured products, and catalysts based on D-amino acids favored the formation of the R-configured alcohol. The combination N-Boc-L-alanine and (R)-phenylglycinol (Boc-L-Ab) or its enantiomer
