Free amino acids can be derivatized with isothiocyanates to phenyl- or methyl-thiohydantoin derivatives. The thiohydantoins can be separated on a CSP with poly-[Af-acryloyl-L-phenylalanine ethylester] (Chiraspher ) as a chiral selector [25]. This CSP offers a known selectivity for many five-membered heterocyclic rings.
