series of modularchiralligands that are derived from aminoacids were prepared and tested for their ability to catalyze the asymmetric addition of alkylzinc reagents to aromatic and aliphatic aldehydes. The ligands contain a tertiary amine, an aminoacid side chain, and a carbamate or amide functional group. One ligand, which was synthesized from Ile, catalyzes the addition of diethylzinc to cyclo
