✦ Synopsis

The (N-benzyl-L-leucinato) copper(II) complex was shown pH titration to coordinate L-amino acids more strongly than D enantiomers. A chiral polymer complex, containing N-alkylated amino acid residue and copper(II) ion, was used partially to resolve some optically active amino acids. Unlike the (N-benzyl-L-amino acidate)-copper(II) complex, the polymer-copper(II) complex coordinates D-amino acids more strongly than L-enantiomers; the effect was explained by formation of (N,N-dialkylated-amino acidate) copper(II) complex in the polymer.

## Abstract A mixture of sodium deoxycholate and β‐cyclodextrin has been used to resolve the enantiomers of the 1‐cyano‐2‐substituted‐benz[L]isoindole and dansyl derivatives of a variety of amino acids. The enantiomers of CBI‐histidine and glutamic acid were resolved with this system unlike the cas
