  • HetPHOX: a new class of easily prepared modular chiral ligands
    作者:Nicole End、Catherine Stoessel、Ulrich Berens、Pierino di Pietro、Pier Giorgio Cozzi
    DOI:10.1016/j.tetasy.2004.06.014
    日期:2004.7
    The synthesis of a new class of modular chiral phosphino-oxazoline ligands containing the diphenylphosphino group at different positions of the heterocyclic backbone is described. HetPHOX ligands were tested in enantioselective allylations and in transfer hydrogenation reactions. The synthesis of the ligands is facile with high enantioselectivity (99% ee) obtained in the Pd-catalyzed addition of malonate to diphenylallyl acetate using ligand 10. (C) 2004 Elsevier Ltd.
