title: Reuse of chiral cationic Pd-phosphinooxazolidine catalysts in ionic liquids: highly efficient catalytic asymmetric Diels-Alder reactions.
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).
