The present study, for the first time, presents a feasible protocol for the preparation of β-cyclodextrin/ imidazolium based dicationic ionic liquid, [βCD/Im](OTs)2, and its application as an efficient and eco-friendly microvessel and host ionic liquid system for the regioselective ring opening of the epoxides in water. No evidence for the formation of diol by-products or side reacti...

1 describes the design, synthesis and operation of an artificial small-molecule capable of synthesizing peptides in a sequence-specific manner. The design of this artificial molecular machine was, in the author's own words, " inspired by the ribosome " ; 2 with several elements analogous to ribosomal protein synthesis (Fig. 1). The tRNA's of conventional translation are substituted by amino aci...
متن کاملAnion recognition in water by a rotaxane containing a secondary rim functionalised cyclodextrin stoppered axle.
The synthesis of a water soluble [2]rotaxane is reported using hydrophilic secondary rim functionalised permethylated β-cyclodextrin derivatives as the axle stopper groups. The rotaxane recognises halide anions in pure water with impressive selectivity over sulfate.
متن کاملSuccessive catalytic reactions specific to Pd-based rotaxane complexes as a result of wheel translation along the axle.
Rotaxane-structure-specific Pd-catalyzed rearrangement of propargyl or allyl urethane groups to oxazolidinone moieties proceeded efficiently. The conversion took place successively by the translation of the wheel along the axle, thus providing a novel macrocyclic catalytic system.
