摘要：
Chiral N,N-dialkylnorephedrines supported on polystyrene resin catalyse the enantioselective addition of dialkylzincs to N-diphenylphosphinylimine, affording optically active N-diphenylphosphinylamines with high enantiomeric excess, The influence on the enantioselectivity of the carbon-chain spacer between the chiral function and polymer resin has been examined. Reaction temperature- and solvent-dependency on the chiral polymer-catalysed reaction has also been examined.
