Popis: Seven new chiral stationary phases obtained from ( S )-phenylalanine derivatives, ( R )-Mosher's acid and ( S )-naproxen were prepared and evaluated. The racemic substances used to test them contained either π-acidic or π-basic sites. The best results were observed when the chiral entity bonded to γ-aminopropylsilica gel was 3,5-dimethylanilido-, 3,5-dimethylbenzoyl- or 3,5-dimethoxybenzoyl-( S )-phenylalanine and -( S )-naproxen.
