Asymmetric catalysis of planar-chiral cyclopentadienylruthenium complexes in allylic amination and alkylation

A new enantioselective allylic amination and alkylation catalyzed by planar-chiral cyclopentadienyl-ruthenium complexes is described. The reports indicate that this is not only the first successful ruthenium-catalyzed asymmetric allylic amination and alkylation, but also the first asymmetric catalysis of planar-chiral complexes of late transition metals.
