A new enantioselective HPLC procedure for the direct resolution of b-amino acids is described, based on the use of a new chiral stationary phase (CSP) containing the macrocyclic glycopeptide antibiotic A-40,926, structurally related to teicoplanin, covalently bonded to silica gel microparticles. The new CSP shows higher enantioselectivity and broader applicability in this field compared to the parent teicoplanin phase. The potential for semi-preparative separations on the A-40,926-CSP is demonstrated for a selected cyclic b-amino acid.

Abstract
A new enantioselective HPLC procedure for the direct resolution of b-amino acids is described, based on the use of a new chiral stationary phase (CSP) containing the macrocyclic glycopeptide antibiotic A-40,926, structurally related to teicoplanin, covalently bonded to silica gel microparticles. The new CSP shows higher enantioselectivity and broader applicability in this field compared to the parent teicoplanin phase. The potential for semi-preparative separations on the A-40,926-CSP is demonstrated for a selected cyclic b-amino acid.File in questo prodotto:
