Enantioseparation of napropamide by supercritical fluid chromatography: Effects of the chromatographic conditions and separation mechanism

Chirality, 2018
Supercritical fluid chromatography (SFC) is already used for enantioseparation in the pharmaceutical industry, but it is rarely used for the separation of chiral pesticides.

Recent advances in electrodriven enantioseparations

Journal of Separation Science, 2012
Capillary electromigration techniques have developed into significant analytical separation tools especially for enantioseparations. While CE can be considered a mature technique as documented by its wide applications, CEC is still in a developmental state despite many research efforts.

Enantioseparation of nonproteinogenic amino acids

Analytical and Bioanalytical Chemistry, 2009
The enantioseparation of structurally related N-protected beta-/gamma-amino acids, beta-/gamma-amino amides, and beta-/gamma-amino nitriles by using six different commercially available chiral stationary phases (CSPs) is reported. The synthetic key step to introduce stereochemical asymmetry into all compounds is an enzymatic kinetic resolution of the ...

Apparent and true enantioselectivity in enantioseparations

Chirality, 2000
The separation factor of two compounds in chromatography is the ratio of their equilibrium constants or retention factors. This parameter is universally employed to investigate their resolution and to optimize the experimental conditions of their analysis. In enantioseparations, the situation is more complex because there is a mixed retention mechanism.

Homochiral metal–organic frameworks for enantioseparation

Chemical Society Reviews, 2021
Contextualising rational structural design, according to the enantioselective mechanisms of homochiral metal–organic frameworks, we discuss enantioselective separations primed to deliver purification performances and analytical utilities thereof.

Recent advances in microchip enantioseparation and analysis

ELECTROPHORESIS, 2020
AbstractThis review summarizes recent developments (over the past decade) in the field of microfluidics‐based solutions for enantiomeric separation and detection. The progress in various formats of microchip electrodriven separations, such as MCE, microchip electrochromatography, and multidimensional separation techniques, is discussed.

Enantioseparation by Thin-Layer Chromatography

2019
Despite the fact that high-performance liquid chromatography is the predominant technique for analytical and preparative enantioseparations, chiral thin-layer chromatography (TLC) may represent an alternative, especially if fast analysis with simple equipment is required.

Enantioseparation with liquid membranes

Journal of Chemical Technology & Biotechnology, 2017
AbstractChiral resolution of racemic products is a challenging and important task in the pharmaceutical, agrochemical, flavor, polymer and fragrances industries. One of the options for these challenging separations is to use liquid membranes. Although liquid membranes have been known for almost four decades and have been used for optical resolutions ...
