Copper(II) complexes of diamino-diamido-type ligands as chiral eluents in the enantiomeric separation of d,l-dansylamino acids by reversed-phase high-performance liquid chromatography
For purpose of studying the mechanism of chiral recognition in high-performance liquid chromatography (HPLC) (reversed phase), a model system is proposed, i.e., copper(II) complexes of diamino-diamido-type ligands containing l-amino acids (AA-NN-n) which added to the eluent are able to perform the e...

Copper(II) complexes of diamino-diamido-type ligands as chiral eluents in the enantiomeric separation of d,l-dansylamino acids by reversed-phase high-performance liquid chromatography |
| abstract |
For purpose of studying the mechanism of chiral recognition in high-performance liquid chromatography (HPLC) (reversed phase), a model system is proposed, i.e., copper(II) complexes of diamino-diamido-type ligands containing l-amino acids (AA-NN-n) which added to the eluent are able to perform the enantiomeric resolution of dansylamino acids on C"8 and C"1"8 columns. Being potentially tetradentate, this system should be more liable to give an apical or outer-sphere interaction with the enantiomer rather than a simultaneous dechelation of two binding sites, as in the classical ligand-exchange mechanism. This model allows the variation of several parameters, such as the structural and electronic features of the initial complexes, their relative stabilities and lipophilicities and their correlation with enantioselectivity in HPLC. |

Being potentially tetradentate, this system should be more liable to give an apical or outer-sphere interaction with the enantiomer rather than a simultaneous dechelation of two binding sites, as in the classical ligand-exchange mechanism. This model allows the variation of several parameters, such as the structural and electronic features of the initial complexes, their relative stabilities and lipophilicities and their correlation with enantioselectivity in HPLC.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Armani, E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dossena, A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Marchelli, R.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Virgili, R.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Chromatography A</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">441(1988), 2, Seite 275-286</subfield><subfield code="w">(DE-627)NLEJ17403282X</subfield><subfield code="w">(DE-600)1491247-8</subfield><subfield code="x">0021-9673</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:441</subfield><subfield code="g">year:1988</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:275-286</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/S0021-9673(01)83871-1</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">441</subfield><subfield code="j">1988</subfield><subfield code="e">2</subfield><subfield code="h">275-286</subfield></datafield></record></collection>
