Several bis-copper(II) complexes with chiral ligands derived from 2-substituted 2-(salicylideneamino)ethanols have been tested as catalysts of enantioselective Michael reactions.The degree of enantioselection is strongly affected by the architecture of the ligand.The best result (75percent e.e.) was obtained for a ligand having a substituent potentially suitable to induce the formation of a bis-tetradentate copper(II) complex with a square pyramidal coordination.
