Three new C2-symmetric chiral amino alcohols (PhOHCHCH2)2NCH2C6H4R (R=OCH3, L1; R=CH3, L2; R=Cl, L3) and their lanthanide complexes LLnCl•2THF (L=L1, L2, L3; Ln=La, Sm, Gd) were prepared and characterized. Fluorescent spectra revealed that some complexes emitted fluorescence. In-situ chiral amino alcohol lanthanide complexes L1/SmCl3•4THF effectively catalyzed asymmetric hydrogenation of aromatic ketone with a conversion of 71% and enantiomeric excess (ee) of 32%.

Key words: lanthanide complex, asymmetric hydrogenation, synthesis, fluorescence, chiral amino alcohol
