Alternative and simple normal-phase HPLC enantioseparation of a chiral amino ac...
Vieira,Joao P. F.; Poletti,Erick F.; Vieira,Renata F. F.; Veredas,Vinicius; Santana,Cesar C.; Nakaie,Clovis R.In this work an alternative chromatographic process was developed for fractionating the (+)-(3R,4R) and ( - )-(3S,4S) enantiomers of the chiral trans β-amino acid trans-2,2,5,5-tetramethylpyrrolidine-3-amino-4-carboxylic acid (POAC), which was protected at its amine group for further coupling to a peptide, polymer or other macromolecule. The HPLC enantioseparation was achieved using a chiral cellulose-based nor...
