The 3,5-dinitrobenzoyl (ฯฎ)-amino acid esters were successfully resolved on (ฯช)-phenylurea chiral stationary phases (CSPs) in a normal phase mode by high-performance liquid chromatography (HPLC). The alcohols used for esterification were methanol, ethanol, and n-propanol. The effects of esterificatio

Three different amounts (i.e., selector coverages) of ristocetin A macrocyclic antibiotic have been covalently bonded to silica gel, packed in stainless steel columns, and evaluated as chiral stationary phases (CSPs) in high-performance liquid chromatography (HPLC). The three columns (i.e., CSPs) we
## Abstract Direct highโperformance liquid chromatographic chiral separation of numerous underivatized unnatural amino acids on a ristocetin Aโbonded chiral stationary phase used in the reversedโphase and in the polar organic chromatographic modes is reported. The effects of different parameters su
