Applications of Green Chemistry in Asymmetric Transfer Hydrogenation and Chiral Separations
… <p>The thermodynamic characteristics of the enantioseparation of the chiral benzyl alcohols under ACN-free RP-HPLC were also investigated. The enantiomers of various benzyl alcohols were separated on derivatized cellulose and amylose chiral stationary phases with methanol/water or …

Applications of Brush-Type Chiral Stationary Phases in New Chromatographic Techniques
Chromatographic enantioseparations are an important class of resolutions by which a chiral stationary phase (CSP) is utilized to affect the separation of a mixture of enantiomers to provide, as the end result, the single enantiomers of the mixture. In the studies described within, three areas …

Investigations of chiral recognition of conformationally rigid chiral stationary phases
… CSPs have been designed specifically for the enantioseparation of underivatized $\beta$-blockers. A systematic study of chromatographic structure-activity relationships for the resolution of $\pi$-acidic dinitrobenzoyl (DNB) amino acid derivatives on several DNB $\pi$-acidic CSPs has been …

The Effects of Methanol and Isopropanol on the Chiral Separation of Dronabinol and Three Related Impurities: A 3 X 3 X 3 Factorial Design
The enantioseparations of Δ9-THC and Δ8-THC on amylose tris dimethylphenylcarbamate CSP was investigated using mobile phases containing 1-3% methanol with 1-7% IPA in n-heptane. A factorial design was used to study the main and interaction effects of these alcohols as measured by the retention …

Identification and enantioselective determination of protein amino acids in fertilizers by hydrophilic interaction and chiral chromatography coupled to tandem mass spectrometry /
… spectrometry was developed for fast and reliable enantioseparation and determination of protein amino acids in HPF samples. Under optimized conditions, the majority (15 of 19) of D/L-amino acid pairs were resolved with a resolution factor (Rs) higher than 1.5 with a run time of 15 min. The method …

Chiral Separations on HPLC Derivatized Polysaccharide CSPs: Temperature, Mobile Phase and Chiral Recognition Mechanism Studies
… between enantiomers and CSP that classifies the enantioseparation to be enthalpy controlled. This behavior was exhibited by racemic 2-methylarylpropionic acids with fused rings that were favorably separated at low temperatures. The other mechanism was associated with positive values for the …

Dispersed and deposited polyelectrolyte complexes and their interactions to chiral compounds and proteins
Polyelectrolyte complexation is a rapidly growing field with applications in functional multilayer (PEM) and nanoparticle (PEC) generation, where PEM films are deposited using Layer-by-Layer technique initiated by Decher and PECs are prepared using mixing-centrifugation technique initiated by our …
