  • Title: Reuse of chiral cationic Pd-phosphinooxazolidine catalysts in ionic liquids: highly efficient catalytic asymmetric Diels-Alder reactions.
    Author: Takahashi K, Nakano H, Fujita R.
    Journal: Chem Commun (Camb); 2007 Jan 21; (3):263-5. PubMed ID: 17299633.
    Abstract:
    Chiral cationic palladium-phosphinooxazolidine catalysts in ionic liquid afforded excellent enantioselectivity in Diels-Alder reactions and the catalyst was easily recycled eight times without any significant decrease in chemical yields or enantioselectivity (89-99%, 88-99% ee).
