Chiral recognition of D- and L-tryptophan in the mobile phase in the presence of the title complex [CuL]2⊕ is the reason for their successful HPLC separation on a conventional achiral reversed-phase column. The separation is based on mixed inclusion–ligand-exchange chromatography, in which the more stable complex [CuL(D-Trp)]⊕ probably has the form shown here.

Abstract
Chiral recognition of D- and L-tryptophan in the mobile phase in the presence of the title complex [CuL]2⊕ is the reason for their successful HPLC separation on a conventional achiral reversed-phase column. The separation is based on mixed inclusion–ligand-exchange chromatography, in which the more stable complex [CuL(D-Trp)]⊕ probably has the form shown here.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
