The polymerized surfactant poly(sodium N-undecylenyl amino L-valinate) [poly(L-SUV)] has been used in micellar electrokinetic capillary chromatography for the chiral separation of various acidic and basic drugs, as well as neutral compounds. Under the conditions studied, poly(L-SUV) was shown to be a very versatile anionic chiral selector in the pH range of 5.6-11. The micelle was used for the enantioseparation of coumarinic anticoagulant drugs with various buffers under moderately acidic… 
OPTIMIZING ENANTIOSEPARATION OF PHENYLTHIOHYDANTOIN AMINO ACIDS WITH POLYMERIZED SODIUM N-UNDECANOYL L-VALINATE IN CHIRAL ELECTROKINETIC CHROMATOGRAPHY
TLDR
Comparisons were made between poly(sodium N-undecanoyl L-norvalinate) (poly (L-SUNV)) and poly(L-SUV) to determine how changing the amino acid head group affects analyte-micelle complexes involved in chiral recognition.
The Use of Poly(Sodium N-Undecanoyl-l-Leucylvalinate), Poly(Sodium N-Undecanoyl-l-Leucinate) and Poly(Sodium N-Undecanoyl-l-Valinate) Surfactants as Chiral Selectors for Determination of Enantiomeric Composition of Samples by Multivariate Regression Modeling of Fluorescence Spectral Data
TLDR
Steady-state fluorescence spectroscopy was employed to investigate the use of chiral polymeric surfactants as chiral selectors in chiral analysis by multivariate regression modeling of spectral data and the ability of the model to correctly predict the enantiomeric composition of future samples was evaluated.
Comparison of Chiral Recognition of Binaphthyl Derivatives with l-Undecyl-Leucine Surfactants in the Presence of Arginine and Sodium Counterions.
TLDR
The data indicate that und-leu has significantly improved chiral selectivity toward 1,1'-binaphthyl-2,2'-diyl hydrogenphosphate (BNP) enantiomers in the presence of arginine counterions in comparison to sodium and that, at least in the case of this study, the enantiomeric form of theArginine did not appear to play a role in the chiralSelectivity.
Molecular recognition by chiral cationic micellar and micelle‐like aggregates in electrokinetic capillary chromatography
TLDR
The mousellar hydrophobic environment, in which amides function as hydrogen bonding sites with solutes, and ceased micellar kinetic association‐dissociation with polymerization are discussed.
A miniaturized analytical method based on molecularly imprinted absorbents for selective extraction of (S)-1,1'-binaphthyl-2,2'-diamine and combinatorial screening of polymer precursors by computational simulation.
TLDR
The proposed method, employed for selective extraction of S-DABN, exhibited promising potential in the application of chiral analysis and was employed by MIP-MTSPE coupled with HPLC, which supports the feasibility of this convenient design process.
