Abstract
TFA-amino acid isopropyl esters can be separated by gas chromatography on capillary columns coated with SF 96. Furthermore, these enantiomeric derivatives can be resolved by GC on the newly synthesized optically active stationary phase, N-TFA-L-phenylalanyl-L-leucine cyclohexyl ester in a short time and with high efficiency.
