Drug delivery properties of macroporous polystyrene solid foams.
PURPOSE Polymeric porous foams have been evaluated as possible new pharmaceutical dosage forms. METHODS These materials were obtained by polymerization in the continuous phase of highly concentrated emulsions prepared by the phase inversion temperature method. Their porosity, specific surface and surface topography were characterized, and the incorporation and release of active principles was...
متن کاملCatalytic Asymmetric Inverse-Electron-Demand Hetero-Diels-Alder Reactions.
In this review, the recent developments in catalytic asymmetric inverse-electron-demand hetero-Diels-Alder reaction, which is recognized as one of the most powerful routes to construct highly functionalized and enantioenriched six-membered heterocycles, are described. The article is organized on the basis of different kinds of electron-deficient heterodienes, including α,β-unsaturated ketones/a...
متن کامل"Inverse-electron-demand" ligand substitution in palladium(0)-olefin complexes.
Ligand substitution reactions are ubiquitous in transition-metal chemistry and catalysis. Investigation of ligand substitution reactions for a series of electron-rich palladium(0)-olefin complexes, (bathocuproine)Pd(nitrostyrene) reveals an unprecedented mechanism in which the metal serves as the nucleophilic partner in an "associative" substitution pathway.
متن کاملHighly accelerated inverse electron-demand cycloaddition of electron-deficient azides with aliphatic cyclooctynes.
Strain-promoted azide-alkyne cycloaddition (SPAAC) as a conjugation tool has found broad application in material sciences, chemical biology and even in vivo use. However, despite tremendous effort, SPAAC remains fairly slow (0.2-0.5 M(-1) s(-1)) and efforts to increase reaction rates by tailoring of cyclooctyne structure have suffered from a poor trade-off between cyclooctyne reactivity and sta...
متن کاملLignin-based Pickering HIPEs for macroporous foams and their enhanced adsorption of copper(II) ions.
Interconnected macroporous foams were synthesized by templating oil-in-water Pickering high internal phase emulsions solely stabilized by lignin particles. They exhibited excellent adsorption capacity for copper(II) ions in aqueous solutions.
