Probing chiral chromatography systems in vacuo: cryogenic ion trap laser spectroscopy of diastereomeric copper( ii )-proline-tyrosine complexes

Kien X. Vo, Tomonori Izu, Keisuke Hirata, Masaaki Fujii, Shun-ichi Ishiuchi, Anne Zehnacker

IR spectroscopy under cryogenic ion trap conditions shows that the copper II complexes with

l
-proline and
d
-tyrosine contain
l
-proline in its zwitterion form, while no zwitterion is observed when both amino acids have the same absolute configuration.
