Chiral ligand-exchange chromatography with Cinchona alkaloids. Exploring experimental conditions for enantioseparation of α-amino acids
(Elsevier Science, 2016-11)
The natural Cinchona alkaloid quinidine as chiral selector in chiral ligand-exchange chromatography was systematically studied. Chromatographic conditions for enantioseparation of twentya-amino acidswere first timestudied ...
Synthesis and spectroscopic characterization of new metal(II) complexes with methionine sulfoxide
(2004-09-20)
Methionine sulfoxide complexes of iron(II) and copper(II) were synthesized and characterized by chemical and spectroscopic techniques. Elemental and atomic absorption analyses fit the compositions K2[Fe(metSO) 2]SO4 · H2O ...

Enantioseparation of -amino acids by means of Cinchona alkaloids asselectors in chiral ligand-exchange chromatography
(Elsevier Science, 2013-07)
A conventional nonchiral column was used for the enantioseparation of several racemic -amino acids (native and derivatized) through the use of Cinchona alkaloids as chiral selectors along with Cu(II) ions in chiral ...
Synthesis and characterization of a new platinum(II) complex with L-mimosine
(Taylor & Francis Ltd, 2005-11-10)
Synthesis and characterization of a new Pt(II)-mimosine complex are described. Elemental, mass spectrometry and thermal analyses for the complex are consistent with the formula [PtCl2(C8H10N2O4)]center dot 1.5H(2)O. C-13 ...
A solid nickel(II) complex with methionine sulfoxide
(Elsevier B.V., 2000-08-10)
Solid Ni(C(5)H(10)NO(3)S)(2) . 2H(2)O complex was prepared and characterized. Electronic absorption spectrum shows an octahedral geometry for the complex. Infrared spectroscopy analysis shows that the metal atom is coordinated ...
