Abstract
Several novel tri- and tetradentate amino alcohol ligands, all derived from (+)-camphor, have been synthesized by using specific N-alkylatio n procedures. The amino alcohols were employed as chiral ligands in th e nickel catalyzed conjugate additions of diethylzine to chalcone and cyclohexenone as model substrates. For the acyclic enone enantioselect ivities up to 83% were achieved. (C) 1997 Elsevier Science Ltd.
