## Abstract New amino acid‐based modular chiral ligands were readily synthesized and used to catalyze the asymmetric conjugate addition of Et~2~Zn to various cyclic enones in the presence of a variety of copper sources. Moderately high __ee__ of up to 72% were obtained using ligand (__S__)‐**1e** u
