Tang, Xiaoying published the artcileThiol-ene click derived structurally well-defined per(3,5-dimethyl)phenylcarbamoylated cationic cyclodextrin separation material for achiral and chiral chromatography, Formula: C16H14O6, the publication is Journal of Separation Science (2018), 41(13), 2710-2718, database is CAplus and MEDLINE.
A novel single sulfoether-bridged cationic per(3,5-dimethyl)phenylcarbamoylated-β-cyclodextrin separation material was prepared by thiol-ene click chem. and characterized by using FTIR spectroscopy, solid-state 13C NMR spectroscopy and elemental anal., which confirmed the correct structure. The separation material exhibited a good achiral separation performance for benzene homologs and phenylamine analogs, especially o-xylene and m-xylene, and m-phenylenediamine and o-phenylenediamine can be discriminated by the (3,5-dimethyl)phenylcarbamoylated cyclodextrins. The chiral resolving ability of the separation material was evaluated by discriminating various isoxazolines, flavonoids, and β-blockers in reversed-phase HPLC. For isoxazolines, the material showed the best chiral discrimination toward 3-aryl-5-(2-oxopyrrolidin-1-yl)isoxazolines, where the resolution for (±)-3-(3-chlorophenyl)-5-phenylisoxaazoline reached 6.03. For flavonoids, it exhibited more efficient separation to the ones with more hydrophobic substituents, with a resolution of 5.93 for 6-hydroxyflavanone. β-Blockers were also enantiosepd. satisfactorily on the material. The as-prepared separation material is a good member of the thiol-ene click derived cyclodextrin stationary phase family.
