英文摘要: A series of new phosphite-pyridine ligands, based on the H-8-binaphthyl backbone, were synthesized and employed in the copper-catalyzed enantioselective 1,4-conjugate addition of diethylzinc to acyclic enones. Ligands derived from (S)-H-8-NOBIN provided better results than their parent ligands in the reaction. Ligand L1 provided excellent ees for trans -4-aryl-3-buten-2-ones (up to 97.8% ee) as substrates. Ligand L2 was very efficient for various para-chalcones, and up to 97.2% ee was achieved. (C) 2003 Elsevier Ltd. All rights reserved.
