摘要：

Phosphinooxazoline (PHOX) ligands are highly effective in Pd catalyzed asymmetric substitutions of allylic compounds. A-nines, malonates, nitronates and other soft nucleophiles were employed. Mechanistic aspects were studied by NMR and x-ray crystal structure analyses. Particular emphasis was placed on highly enantioselective allylic substitutions at cyclic substrates.
