N2 - Diastereomeric P,S-bidentate phosphoramidite ligands with TADDOL core and (1R,2S)-1,2-diphenyl-2-(phenylthio)-ethan-1-amine residue were synthesized. These ligands provided up to 76% ee in the Pd-catalyzed alkylation of (E)-1,3-diphenylallyl acetate with dimethyl malonate, up to 70% ee in the amination of this substrate with pyrrolidine, and 89–95% ee in the Rh-catalyzed asymmetric hydro- genation of dimethyl itaconate and methyl (Z)-2-acetamido-3-arylacrylates. The different contributions of diastereomeric chiral inducers to the catalytic outcome are discussed.
