Wang, Yong published the artcile“Click” immobilized perphenylcarbamated and permethylated cyclodextrin stationary phases for chiral high-performance liquid chromatography application, Category: tetrahydropyran, the publication is Journal of Chromatography A (2010), 1217(31), 5103-5108, database is CAplus and MEDLINE.
Two cyclodextrin-based chiral stationary phases were prepared by immobilization of functionalized mono-6-azido-β-CD derivatives to alkynyl modified silica via click chem. and applied to the HPLC enantioseparation of various chiral compounds The perphenylcarbamated CD CSP (CCP-CSP) exhibited excellent chiral recognition of a wide range of analytes including racemic aryl alcs., flavonoids, bendroflumethiazide, atropine and some β-blockers. Methanol proved to be a better organic modifier than acetonitrile for most of the analytes with the exception of bendroflumethiazide. The click chem. immobilized permethylated CD CSP (CCM-CSP) afforded poor chiral recognition for most analytes, but could resolve nonaromatic ionone derivatives which were not separated on CCP-CSP. Probably resolution with cyclodextrin derived CSPs depend on a complex interplay of host’- guest’ inclusion, hydrogen bonding, π-π and hydrophobic interactions.
