J. Planar Chromatogr. 11, 346-349 (1998). TLC of the enantiomers of several unusual aromatic amino acids (phenylalanine, tyrosine, histidine, and tryptophan analogs, and analogs containing tetralin or 1,2,3,4-tetrahydroisoquinoline skeletons) synthesized in racemic or homochiral form on chiral plate with acetonitrile - methanol - water 4:1:1; 4:1:2 or acetonitrile - methanol - water - diisopropylethylamine 40:10:20: 1. Visualization with ninhydrin.
Chromatographia 52 (9/10), 648-652 (2000). Reversed-phase TLC of enantiomers of dansyl amino acids with varying structures to determine the structural features necessary for enantio-selection by beta-cyclodextrin (b-CD), a chiral mobile phase additive. 8 DNS-DL-amino acid pairs were resolved for the first time using the methodology.
Acta Chrom. 11, 233-237 (2001). Conditions for separation of racemic mixtures of fatty acids by use of a mobile phase containing a chiral compound as additive and on a chiral stationary phase. TLC separation of the enantiomers of DL-alpha-hydroxypalmitic acid on silica gel with acetone – hexane – hydrochloric acid 3:5:2 containing 1 % L-alanine, detection by dipping in 2 % aqueous sodium hydroxide solution. TLC of the enantiomers of DL-12-hydroxystearic acid on silica gel F254 with hexane – acetonitrile – acetic acid – hydrochloric acid 5:2:1:2 containing 2 % L-alanine, detection by dipping in 2 % aqueous sodium hydroxide solution. Separation of the enantiomers of DL-12-hydroxyoleic acid on chiral plate with acetone – water 3:2, detection by treatment with iodine vapor. Isomers were characterized by calculation of their optical topological indexes.
J. Planar Chromatogr. 21, 33-37 (2008). Pressurized planar electrochromatography (PPEC) and TLC of tryptophan and valine on chiral plates (with D-4-hydroxyproline as the chiral selector) prewashed with methanol, with acetonitrile - methanol - water - 1.25 mM citric acid and disodium phosphate buffer 7:1:1:1. Detection by spraying with a solution of ninhydrin in acetone, followed by heating at 110 °C for 5 min.
Acta Chromatographica 20(3), 367-382 (2008). Investigation of the separation of the enantiomers of D,L-lactic acid with transition metal cations (i.e., Co2+, Ni2+, and Mn2+, rather than Cu2+ as stated in the literature) used to impregnate the silica gel. The goal was first to achieve a resolution that might enable the quantification of the two lactic acid enantiomers and second to gain deeper insight into the mechanism of separation. For comparison D,L-lactic acid was chromatographed on non-impregnated silica gel, and then efficient separation conditions with the Ni2+ and Co2+ cations were established, which outperformed the previously reported procedure with Cu2+. The Mn2+ cation proved unsuitable for the purpose. The enantiomers of D,L-lactic acid were also separated on non-impregnated silica gel, which seems yet more proof of the microcrystalline chirality of silica gel used as stationary phase and of its substantial contribution to the enantiomer separation investigated.
J. Planar Chromatogr. 30, 333-339 (2017). Review of applications of chiral TLC to demonstrate the dynamic phenomenon of the spontaneous oscillatory chiral conversion with the low molecular weight carboxylic acid. The principles of oscillatory processes and chiral conversion and condensation, as well as selected examples of the applicability of chiral TLC to dynamic studies were reviewed.
J. Chromatogr. 472, 277-283 (1989). TLC of enantiomeric amides on naphtyl-ethyl-urea-aminopropyl-bonded silica with hexane - isopropanol - acetonitrile 20:8:1. Detection under UV 254/360 nm. Discussion of the preparation of the chiral stationary phase.
J. Chromatogr. 553, 497-501 (1991). Description of the preparation of a two-phase "pirkle" modified amino-bonded TLC plate for the separation of enantiomers. Preparation of the plate by partially immersing an HPTLC plate in a solution of chiral selector N-(3,5-dinitrobenzoyl)-L-leucine. Use of the modified portion to separate the enantiomers of the model compounds 2,2,2-trifluoro-(9-antryl)ethanol and 1,1'-binaphthol. Elution of the separated enantiomers onto the unmodified portion of the plate using continuous development. Detection by fluorescence quenching.
