  • Title: Multinuclear Cu-catalysts based on SPINOL-PHOS in asymmetric conjugate addition of organozinc reagents.
    Author: Endo K, Hamada D, Yakeishi S, Ogawa M, Shibata T.
    Journal: Org Lett; 2012 May 04; 14(9):2342-5. PubMed ID: 22519845.
    Abstract:
    Multinuclear Cu/Zn complex-catalyzed efficient asymmetric conjugate addition of organozinc reagents to acyclic and cyclic enones has been developed in the presence of a wide variety of regioisomeric chiral diols bearing phosphorus moieties as ligands. The regioisomeric SPINOL-PHOS ligands based on a SPINOL architecture showed an unexpected inversion of stereoselectivity.
