Restoring order: YIII, EuIII, and ErIII tris(ligand) complexes of a new chiral alkoxide ligand, tBu2P(O)CH2CH(tBu)OH (HL), preferentially form as C3-symmetric diastereomers. Thus racemic HL affords (RRR)- and (SSS)-LnL3 complexes, which are active catalysts for the stereoselective polymerization of rac-lactide to afford highly isotactic polylactic acid.
