Anionic species are omnipresent and involved in many important biological processes. A large number of artificial anion receptors has therefore been developed. Some of these are capable of mediating transmembrane transport. However, where transport proteins can respond to stimuli in their surroundings, creation of synthetic receptors with stimuli-responsive functions poses a major challenge. Herein, we give a full overview of the stimulus-controlled anion receptors that have been developed thus far, including their application in membrane transport. In addition to their potential operation as membrane carriers, the use of anion recognition motifs in forming responsive membrane-spanning channels is discussed. With this review article, we intend to increase interest in transmembrane transport among scientists working on host–guest complexes and dynamic functional systems in order to stimulate further developments.

The invention discloses a nitrile alpha-alkylation reaction catalyst and application thereof. The nitrile alkylation reaction catalyzed by pyridine-pyridine-imidazoline asymmetric pincerlike rutheniumcompounds has a reaction general formula shown in the specification, and in the general formula, a catalyst is a pyridine-pyridine-imidazoline asymmetric pincerlike ruthenium compound, R1 is aryl, and R2 is aryl or alkyl, wherein aryl is phenyl, p-methylphenyl, p-methoxyphenyl, p-chlorophenyl, thiophene and the like, and alkyl is n-butyl, phenylpropyl and the like. The synthesis method comprisesthe following synthesis steps: adding an asymmetric pincerlike ruthenium compound, an alkali, a nitrile compound and an alcohol into a solvent for reaction, and after the reaction is finished, conducting separating and purifying to obtain a corresponding target product. Alcohol is used as an alkylating reagent, generated water is a unique by-product, the method conforms to the ideas of atom economy and environmental friendliness, and meanwhile, the method has the advantages of use of a catalytic amount of alkali, short reaction time, economy and the like.

Nitrile alpha-alkylation reaction catalyst and application thereof

The invention discloses a bis(2-heteroarylimidazo[1,2-a]pyridin-3-yl)sulfide compound and a synthetic method thereof. The synthetic method comprises the steps of adding a 2-heteroaryliidazo[1,2-a]pyridine compound and phenyl isothiocyanate into a reaction tube in the air environment, adding cuprous iodide and 4-dimethylaminopyridine, adding a solvent, and allowing to react at 90 DEG C for 12 hours; extracting after the reaction is over, carrying out chromatographic separation, and drying to obtain the target product. The low-price metallic copper (I) is used as a catalyst in the reaction, 4-dimethylaminopyridine is used as a base, and N,N-dimethylformamide is used as a reaction solvent; therefore, sulfur bridging connection between the imidazo[1,2-a]pyridine compound and phenyl isothiocyanate is achieved. The synthetic method is significant to the research and application of sulfur bridging reaction of imidazo[1,2-a]pyridine compounds.
