Copper(I1) complexes of 6)-phenylalaninamide have been successfully used for the direct enantiomeric separation of unmodified (R, S)-a-hydroxy acids in reversed phase high-performance liquid chromatography (RP-HPLC). The effect of various parameters (pH, eluent polarity, selector concentration) on e

A study developing enantiomeric separations by metal chelate additives to the mobile phase in reversed-phase liquid chromatography is reported. In particular the use of Cu(I1) complexes of L-prolinamide (L-ProNH,) and Lvalinamide (L-ValNH,) is examined and discussed. Interestingly, for a series of D
