Chiral ionic liquids in chromatographic and electrophoretic separations
(2014)This report provides an overview of the application of chiral ionic liquids (CILs) in separation technology, and particularly in capillary electrophoresis and both gas and liquid chromatography. There is a large number of ...

Chiral separation of the clinically important compounds fucose and pipecolic acid using ce: Determination of the most effective chiral selector
(2013)In this study, simple electrophoretic methods were developed for the chiral separation of the clinically important compounds fucose and pipecolic acid. In recent years, these analytes, and particularly their individual ...

Chiral separations using a polypeptide and polymeric dipeptide surfactant polyelectrolyte multilayer coating in open-tubular capillary electrochromatography
(2004)A polyelectrolyte multilayer (PEM) coating consisting of the polypeptide, poly(L-lysine) hydrobromide, poly(L-lysine) and the polymeric dipeptide surfactant, poly(sodium undecanoyl-L-leutcyl-alaninate), poly(L-SULA), is ...

Combined use of cyclofructans and an amino acid ester-based ionic liquid for the enantioseparation of huperzine A and coumarin derivatives in CE
(2015)Cyclofructans (CFs) and their derivatives have recently been proven to be efficient chiral selectors (CSs) for the enantioseparation of several analytes in CE, HPLC, and GC. In this study, the chiral separation ability of ...

Facile preparation of polysaccharide-coated capillaries using a room temperature ionic liquid for chiral separations
(2013)In this study, the dissolution of polysaccharides into an ionic liquid was investigated and applied as a coating onto the capillary walls of a fused-silica capillary in open-tubular CEC. The coating was evaluated by examining ...

Fast Screening of Whole Blood Samples and Pharmaceutical Compounds for Enantiorecognition of Free L-T3, L-T4, and D-T4
(2015)A fast screening method of whole blood was proposed for enantiorecognition of free L-T3, L-T4, and D-T4. Stochastic microsensors based on four inulins (IN, IQ, TEX, and HD) immobilized on diamond paste (DP) were used for ...

The first one-pot synthesis of a chiral pentakis-adduct of C60 utilising an opened-structure malonate tether
(2013)A pentakis-adduct of C60 with an incomplete octahedral addition pattern was synthesised via a one-pot procedure using a tether equipped with five malonate moieties. The five-fold Bingel cyclopropanation of C60 was completely ...

Regio- and stereoselective synthesis of enantiomerically pure [60]fullerene tris-adducts with an inherently chiral e,e,e addition pattern
(2005)The synthesis and flash column chromatographic separation of c enantiomerically pure tris-adducts of C60 with an e,e,e-addition pattern is achieved via cyclopropanation with chiral D3-symmetrical cyclo-tris(malonate) ...

Remote functionalization of C60 with enantiomerically pure cyclo-[2]-malonate tethers bearing C12 and C14 spacers: Synthetic access to bisadducts of C60 with the inherently chiral trans-3 addition pattern
(2013)In this Article, we describe the synthesis of two optically pure diols bearing a 1,2-diol moiety masked as an isopropylidene acetal group and long alkyl chains comprised of 12 and 14 carbon atoms, respectively. The synthetic ...

An unexpected stereoisomerism in enantiomerically pure trisadducts of C60 with an inherently chiral trans-3,trans-3,trans-3 addition pattern
(2014)We have synthesized and isolated two C2-symmetric enantiomerically pure trisadducts of C60 with an inherently chiral trans-3,trans-3,trans-3 addition pattern with the aid of an enantiopure cyclo-tris-malonate tether. An ...

Use of chiral amino acid ester-based ionic liquids as chiral selectors in CE
(2013)In this study, the applicability of a chiral ionic liquid (CIL) as the sole chiral selector in CE was investigated for the first time. In particular, five amino acid ester-based CILs were synthesized and used as additives ...
