  Concepts for ligand design in asymmetric catalysis: a study of chiral amino thiol ligands

  摘要：

  A series of new chiral sulfur-nitrogen chelate ligands, derived from amino acids, has been synthesised rationally. Fruitless experiments into catalytic asymmetric conjugate additions and desymmetrisation of meso-epoxides led us to analyse our ligands in the catalytic asymmetric addition of diethylzinc to aromatic aldehydes. These latter experiments were successful with chiral benzylic alcohols being obtained in up to 82% enantiomeric excess. (C) 1998 Elsevier Science Ltd. All rights reserved.
