Facile Diastereoseparation of Glycosyl Sulfoxides by Chiral Stationary Phase
Chirality, 2016AbstractSeparation of the diastereomers of glycosyl sulfoxides differing in the sulfur chirality has been difficult. This article presents a fast and scalable method for their diastereoseparation using a chiral stationary phase. The usefulness of this method was demonstrated in a 500‐mg scale separation within 20 min, and in the separation of ...

Chirality
ABSTRACTInclusion complexation, hydrogen bonds, π–π interaction, dipole–dipole interaction, and steric hindrance effect all contribute to the enantioseparation ability of cyclodextrin (CD) or CD derivatives. In this work, one native cationic CD chiral stationary phases (SHCDCSP) and four derivatized CD‐CSPs, namely, per(4‐trifluoromethyl ...

Antibody-Mimicking Polymers as Chiral Stationary Phases in HPLC
Analytical Chemistry, 1996Antibody-mimicking synthetic polymers, selective for various optically active amino acid derivatives and peptides, were prepared by noncovalent molecular imprinting. A novel approach, in which the branched, trifunctional cross-linkers pentaerythritol triacrylate and 2,2-bis(hydroxymethyl)butanol trimethacrylate were copolymerized with methacrylic acid,

Chiral stationary phases for the liquid chromatographic separation of pharmaceuticals
Journal of Pharmaceutical and Biomedical Analysis, 1988Biological systems exhibit remarkable enantioselectivity which is important in biosynthesis, metabolism, storage and transport processes. It is, therefore, not surprising that the chirality of, for example, pharmaceuticals, pesticides and agrochemicals, has become the focus of extensive research in many laboratories throughout the world.

Synthesis and Spectroscopic Evaluation of Chiral Selectors in Crial Stationary Phases
2005The enhanced demand for enantiomerically pure compounds (EPC) has led to the development of a variety of enantioselective separation methods. Like very useful one emerged liquid chromatography which use chiral stationary phases (CSPs). One of the most used CSPs named brush or Pirkle type CSPs consist of small optically active compounds covalently bound
