designed a new library of readilyavailable, highly modular phosphite-phosphoramidite ligands for asymmetricallylicsubstitutionreactions. They are easily prepared in one step from commercially available chiral 1,2-amino alcohols. The introduction of a phosphoramidite moiety into the ligand design is highly advantageous for the product outcome. This ligandlibrary affords high reaction rates (TOFs of
