Amino alcohol‐derived chiral stationary phases

Chirality, 2023
AbstractAn updated minireview of chiral stationary phases (CSPs) based on amino alcohols is presented. In this minireview, we focused on amino alcohols as starting materials in preparation of chiral catalysts for asymmetric organic synthesis and CSPs for chiral separations.

Molecule imprinting chiral stationary phase

Biomedical Chromatography, 1999
Molecule imprinting polymers (MIPs) with high chiral selectivity for N(alpha)-protected amino acids were synthesized in polar solvent using acrylamide (AM) or combined functional monomer methacrylic acid (MAA) + vinyl pyridine (VP). Factors that influence the chiral selectivity of MIPs and mechanisms of the chiral recognition process were investigated.

Hexahelicene chiral stationary phase

Journal of Chromatography A, 1988
Abstract Hexahelicen-7-ylacetic acid methyl ester was synthesized and resolved on a column of (+)-2-(2,4,5,7-tetranitro-9-fluoren ylideneamino-oxy)propionic acid on aminopropyl silica. Following hydrolysis, the (+)-hexahelicen-7-ylacetic acid was bonded by carbodiimide coupling to aminopropyl silica.
