Chiral phosphinooxazolines (PHOX ligands), which coordinate to a metal cent
er with a N- and a P-atom, allow effective enantio-control in a variety of
metal-catalyzed reactions. They are readily synthesized, and because of the
ir modular structure, the steric and electronic properties can be tailored
for a specific application by variation of the oxazoline ring, the backbone
, and the phosphine moiety.
