Abstract
A series of 6-monohalo (Cl, Br, and I) β-cyclodextrin derivatives with various types of methylations were synthesized via a diazotization/nucleophilic displacement reaction from the corresponding methylated cyclodextrin amines. All four starting compounds (6A-amino-6A-deoxy derivatives of native β-CD, per-6-O-methyl-, per-2,3-O-methyl-, and per-2,3,6-O-methyl-β-CD) were found to have different reactivities under the same reaction conditions. Unsubstituted and fully per-O-methylated cyclodextrin amines undergo fast transformation, giving lower yields of the monohalogenated product. The selectively methylated cyclodextrin amines react remarkably slower and provide almost complete conversion into the desired monohalogenated compound. A pure product was, in several cases, successfully isolated with simple purification techniques (extraction and precipitation), allowing large-scale preparations. This new method opens the way for preparing poorly investigated monofunctionalized selectively methylated cyclodextrins.

Abstract
A simple and efficient radical C-H functionalization to access modified cyclodextrins (CDs) has been developed. The well-defined conformation of glycosidic and aglyconic bonds in α-, β-, and γ-CDs favors the intramolecular 1,8-hydrogen atom transfer (HAT) promoted by the 6I-O-yl radical, which abstracts regioselectively the hydrogen at C5II of the contiguous pyranose. The C5II-radical evolves by a polar crossover mechanism to a stable 1,3,5-trioxocane ring between two adjacent glucoses or alternatively triggers the inversion of one α-d-glucose into a 5-C-acetoxy-β-l-idose unit possessing a 1C4 conformation. The 6I,IV- and 6I,III-diols of α- and β-CDs behave similarly to the monoalcohols, forming mostly compounds originating from two 1,8-HAT consecutive processes. In the case of 6I,II-diols the proximity of the two 6-O-yl radicals in adjacent sugar units allows the formation of unique lactone rings within the CD framework via a 1,8-HAT-β-scission tandem mechanism. X-ray diffraction carried out on the crystalline 1,4-bis(trioxocane)-α-CD derivative shows a severe distortion toward a narrower elliptical shape for the primary face.

Abstract
The separation and retention behavior of five aromatic carboxylic acid isomers was investigated by means of high-performance liquid chromatography (HPLC) using a beta-cyclodextrin bonded phase with s-triazine ring in the spacer. The influence of mobile phase pH on the retention was examined. The presence of s-triazine moiety in the spacer enhances greatly the selectivity of the isomers of aromatic carboxylic acids. Baseline separations of the five aromatic carboxylic acid isomers were achieved. In particular, the isomers of toluic, aminobenzoic, nitrobenzoic and hydroxybenzoic acid were successfully and effectively separated. The chromatographic results indicate that, in addition to inclusion complexation, pi-pi interaction and hydrogen bonding interaction between the bonded phase and analytes play significant roles in the retention of these acid isomers. Different elution orders were observed for these acidic solutes with different substituents. Possible retention mechanisms are discussed.

Abstract
Pragmatic comparison of pressure dependent retention for differing cyclodextrin rim chemistries is assessed using controlled-pressure HPLC. For pressure differences of <300 bar, systematic shifts in solute capacity factor are observed for both native and methylated beta-cyclodextrin stationary phases. In addition to the importance of this observation for the practice of liquid chromatography, this technique can also be implemented in the fundamental determination of the influence of rim chemistry on the cyclodextrin partial molar volume both with and without solute inclusion. That is, pressure-controlled measurements provide a direct comparison between the partial molar volumes for native cyclodextrin (CD) and methylated cyclodextrin (MCD) in the presence and absence of the complexing solute (comp). Surprisingly, direct comparison of the measured partial molar volumes for the two rim chemistries indicates that the presence of neutral solutes does not contribute significantly to the volumetric component of complexation, V(comp,CD) - V(comp,MCD) approximately V(CD) - V(MCD). In contrast, their ionized counterparts are shown to exhibit marked rim chemistry differences in the partial molar volume of cyclodextrins with and without anion inclusion, V(comp(-),CD) - V(comp(-),MCD) < V(CD) - V(MCD). Not previously demonstrated by direct chromatographic measurement, these results have interesting implications for advancing the fundamental understanding of host-guest solvation properties.

Abstract
The correlation between the capacity factors of enantiomers of chiral barbiturates and the concentrations of beta-cyclodextrin, heptakis(2,6-di-O-methyl)-beta-cyclodextrin and heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin dissolved in the mobile phase was studied using LiChrosorb RP-18 as the stationary phase. Owing to the very strong adsorption of permethylated beta-cyclodextrin on the ODS surface a chiral stationary phase is generated dynamically and forms complexes with the solutes; this mechanism has been found to be the only factor responsible for the chiral recognition of the investigated compounds at all applied concentrations. The inclusion of barbiturates in the cavities of permethylated beta-cyclodextrin involves a distinct and entirely new kind of enantioselectivity compared with that observed for beta-cyclodextrin and its dimethyl derivative. Using permethylated beta-cyclodextrin baseline resolutions have been obtained with barbiturates containing a chiral centre in the heterocyclic ring or in the aliphatic side-chain.

Abstract
A high-performance liquid chromatographic (HPLC) support was prepared, based on silica beads coated with a beta-cyclodextrin-containing polymer, which allows the elution of solutes in order of their affinity for beta-cyclodextrin. Binding constants were determined from the retention data for drugs eluted with pure buffer on the new support and good agreement was observed with results obtained by the Hummel and Dreyer method, previously used in HPLC studies of drug-protein interactions.

Abstract
The separation of positional isomers of several substituted benzoic acids was studied using two different columns, i.e. amine and beta-cyclodextrin bonded silicas, at appropriate normal-phase conditions. Although some other columns do separate substituted benzoic acids, particularly the octadecylsilica column in a reversed-phase mode, the present separation under simple normal-phase, isocratic conditions is unique. In particular, the retention order of these acids for the amino bonded-phase column can be roughly predicted using the pKa values of the analytes. On the other hand, due to the strong interaction between substituted benzoic acids and the beta-cyclodextrin bonded phase, a small amount of acetic acid has to be added into the mobile phase to overcome band broadening and tailing problems. Possible retention mechanisms are also discussed.
