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.
