| Abstract: | New phosphine-imine and phosphine-amine chiral ligands which were easily prepared from d-gluco-, d-galacto- and d-allosamine furnished a high level of enantiomeric excess (up to 99%) in the Pd(0)-catalysed asymmetric allylic alkylation of racemic 1,3-diphenyl-2-propenyl acetate with malonates. |
