Reaction at the interface of an organic solution containing an acidic reactant and an aqueous alkaline solution containing nonreducing carbohydrates such as sucrose, sugar alcohols, cyclodextrins, and polysaccharides imparts a specificity to the reaction for one or more of the primary alcohol groups of the carbohydrate reactant. The resulting activated, nonreducing carbohydrate intermediate can...

Injected-ion mobility/mass spectrometry techniques have been used to measure the reduced ion mobilities for negatively charged raffinose, melezitose and α-, β-, and γ-cyclodextrins formed by electrospray ionization. At low injection energies, the mass spectra are dominated by negatively charged (deprotonated) parent ions. At high injection energies, the mass spectra recorded for the cyclodextri...

Diisobutylaluminium hydride (DIBAL-H) mediated reductive removal of benzyl groups was investigated for perbenzylated alpha-, beta- and gamma-cyclodextrins using DIBAL-H in hexane as the reagent. It was found that under the new conditions, the debenzylation can be better controlled to provide sequentially tri- and tetra-debenzylated products in moderate yields and in a regioselective manner. In ...

Inclusion complexes of cyclodextrins with organometallic coordination compounds of Pd, Pt, Rh, Fe, Ni, and Ru have been used to produce porous metal-silica hybrid materials. The cyclodextrins are templates for the structure of the silica and lead to a uniform “wormtype” pore system. After the templating step the organometallic compounds can be employed as in situ precursors for the preparation ...

Template-induced kinetic trapping of specific cyclodextrins in enzyme-mediated dynamic combinatorial libraries linear and cyclic α-glucans enables the one-step synthesis from maltose water.

background today, the use of cyclodextrins (cds) is a major concern in drug formulations to improve solubility and stability of compounds. it has been known that cds can reduce the antimicrobial effectiveness of preservatives by formation of inclusion complexes. objectives in this study the interaction between commonly used preservatives, benzalkonium chloride (bzcl) or methyl paraben (mp), wit...

Multiwall carbon nanotubes have been efficiently suspended into water thanks to methylated β-cyclodextrins (CDs) containing a triazole group, itself substituted in the 4-position by hydrophilic moieties.
