Chiral β-diketonate ligands of ‘pseudo planar chiral’ topology: enantioselective synthesis and transition metal complexation

A practical enantioselective synthesis of chiral β-diketonate ligands , which are of ‘pseudo planar-chiral’ topology, is described. Additionally, the first chiral bis(diketonates) , ligands of C2-symmetry that are isoelectronic with respect to related salen ligand systems, have been prepared. Protocols for the metallation of ligands , and are reported.
