Abstract

Sorbic acid has a system of conjugated double bonds which makes it able to undergo nucleophilic addition reactions with certain functions. The interactions between sorbic acid and amine functions present in the endogenous constituents of food were quantified. The formation of new products was demonstrated and the underlying mechanisms studied using ethyl sorbate and various amines. HPLC, GC, GC-SM and NMR analyses of the reaction mixtures enabled the products to be isolated and identified. The addition reactions led, at 20 degrees C, to linear monoadducts and, at 50 degrees C and 80 degrees C, to cyclic derivatives resulting from double addition.

Optimization of the methods for introduction of amine groups onto the silica nanoparticle surface.

The luminescent silica nanoparticle has attracted the researchers' concentration in bioanalysis recently. Its extensive application is based on the immobilization of various biomolecules such as deoxyribonucleic acid, antibody, and so forth onto the surface. By comparing different introduction methods of amine groups, it was confirmed that the "two-step" route is more preferable by adding tetraethyl orthosilicate and 3-aminopropyl-(triethoxyl)silane in sequence, to attain ideal amine-modified silica nanoparticles. On this basis, carboxyl groups were derived from amine groups on the nanoparticle surface and then were activated by 1-ethyl-3-3-(3-dimethylaminopropyl) carbodiimide hydrochloride and N-hydroxy-succinimide. Finally, mouse monoclonal antihuman CD71 antibody (McAb CD71) and transferrin were effectively linked with the carboxyl groups and successfully labeled the receptors in the membrane of fibroblast cells, respectively.

Reactivity of indanedioneketene dimer with amines.

The highly reactive indanedioneketene 5, resulting from the thermal decomposition of phenyliodonium ylide of 2-hydroxy-1,4-naphthoquinone (lawsone, 4), in the absence of nucleophiles dimerizes to the corresponding tetraoxo spiro oxetanone 6 in quantitative yield. This oxetanone exhibits an interesting reactivity toward amines.

Amine-promoted, organocatalytic aziridination of enones.

A novel method is presented using N-N ylides (prepared by in situ amination of a tertiary amine) for the aziridination of a range of enone systems. The amine may be used sub-stoichiometrically, and promising levels of enantioselectivity are observed with quinine as promoter. [reaction: see text].
