Abstract: A series of lanthanide tris(β-diketonates) functioned as useful chirality probes in the vibrational circular dichroism (VCD) characterization of biological amino alcohols. Various chiral amino alcohols induced intense VCD signals upon ternary complexation with racemic lanthanide tris(β-diketonates). The VCD signals observed around 1500 cm(-1) (β-diketonate IR absorption region) correlated well with the stereochemistry and enantiomeric purity of the targeted amino alcohol, while the corresponding monoalcohol, m… Show more

“…In 1977, the first circularly polarized luminescence (CPL) spectra from optically inactive Eu III (fod) 3 , Eu III (dpm) 3 , Tb III (fod) 3 , and other two Eu II complexes dissolved in ( R )-/( S )-α-phenylethylamine are reported by hypothesizing the Pfeiffer effect (fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate, dpm: dipivaloylmethane or 2,2,6,6-tetramethyl-3,5-heptanedione) (Brittain and Richardson, 1977a ; Brittain, 1980 ). These pioneering CPL studies further stimulated many researchers to investigate CPL and CD spectroscopic characteristics of optically inactive lanthanide complexes in the presence of amino acids, monosaccharides, malic acid ascorbic acid, cyclic glycols, DNA, and other chiral chemical influences (Luk and Richardson, 1974 ; Brittain and Richardson, 1977b ; Madaras and Brittain, 1980 ; Brittain, 1981 , 1984 ; Richardson, 1982 ; Yan et al, 1982 ; Huskowska and Riehl, 1995 ; Muller and Riehl, 2005 ; Muller, 2009 ; Iwamura et al, 2012 , 2016 ; Miyake et al, 2014 ; Wu et al, 2016 , 2019 ; Jalilah et al, 2018 ; Lunkley et al, 2018 ; Wu and Bouř, 2018 ; Taniguchi et al, 2019 ). An outer-sphere intermolecular interaction between the Δ-/Λ-mixture lanthanide III (Ln III ) complex and the chiral additives is responsible for the equilibrium shift, as detectable by emerging CPL spectra.…”

“…A so-called "switchable amplification of VCD" for chiral structures was reported to amplify VCD signals (Domingos et al, 2014b). Another way is to use lanthanide tris(β-diketonates) as useful probes in the stereogenic center determination of biological amino alcohols near 1500 cm −1 (β-diketonate IR absorption region) due to the formation of ternary complexation with racemic lanthanide tris(βdiketonates) (Miyake et al, 2014).…”
