A wide series of L-phenylalanine tetraamide selectors (Phe-n-O-TA) were synthesized and used as stationary phases for chiral resoln. of D,L-amino acids by capillary gas chromatog. The influence of length and polarity of the oxaalkanoyl bridge spacing the diamide chains of the selectors and the effects of steric hindrance on sepg. power were studied. The characteristics of the chiral columns and the sepn. factors of D,L-n-butyl-N-trifluoroacetyl amino esters are reported.
