Abstract
AbstractA library of amphiphlic polystyrene‐poly(ethylene glycol) (PS‐PEG) resin‐supported chiral phosphine ligands was prepared by the split method using porous miniature reactors. A polymeric (R)‐2‐(diphenylphosphino)binaphthyl (MOP) ligand anchored onto the PS‐PEG resin by an (S)‐alanine tether unit was identified through the library‐based screening to be an effective chiral ligand for the asymmetric palladium‐catalyzed π‐allylic substitution under heterogeneous aqueous conditions.
