Chiral phosphinooxazolines with a pentamethylferrocene backbone--synthesis and use as ligands in asymmetric catalysis.
Novel phosphinooxazolines, containing a unit of central and a unit of planar chirality in a matched case combination, have been successfully tested in the Pd-catalyzed asymmetric allylic substitution with cycloalkenyl acetates as substrates.
