A cascade Aza-Cope/Aza-prins cyclization leading to piperidine derivatives

The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines has been explored. The use of glyoxalic acid as the carbonyl component afforded bicyclic structures as a result of the internal carboxylate anion trapping the intermediate cation. The unimolecular bis-, tris-, and tetrakis(homoallylamine)s efficiently delivered the appended bis-, tris- and tetrakis(piperidine-4-ol)s (tripod and crucifix shape, respectively) as new entities. The latter compound served as an excellent ligand in the Suzuki-Miyaura cross-coupling reaction to synthesize incrustoporin. The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines is described. A unimolecular tetrapiperidine derivative, which resulted from this strategy, was employed as a ligand in the Suzuki-Miyaura cross-coupling reaction of an α-iodobutenolide with an arylboronic acid in an efficient synthesis of incrustoporin and its analogues.

Dumbbells, trikes and quads: Organic-inorganic HYBRID NANOARCHITECTURES BASED on "cLICKED" GOLD NANOPARTICLES

The controlled assembly of gold nanoparticles in terms of the spatial arrangement and number of particles is essential for many future applications like electronic devices, sensors and labeling. Here an approach is presented to build up oligomers of mono functionalized gold nanoparticles by the use of 1,3-bipolar azide alkyne cycloaddition click chemistry. The gold nanoparticles of 1.3 nm diameter are stabilized by one dendritic thioether ligand comprising an alkyne function. Together with di-, tri- and tetra-azide linker molecules the gold nanoparticle can be covalently coupled by a wet chemical protocol. The reaction is tracked with IR and UV-vis spectroscopy and the yielded organic-inorganic hybrid structures are analyzed by transmission electron microscopy. To evaluate the success of this click chemistry reaction statistical analysis of the formed oligomers is performed. The geometric and spatial arrangements of the found oligomers match perfectly the calculated values for the used linker molecules. Dimers, trimers and tetramers could be identified after the reaction with the corresponding linker molecule. The results of this model reaction suggest that the used click chemistry protocol is working well with mono functionalized gold nanoparticles. Functionalized gold nanoparticles are interlinked by a click chemistry protocol into defined oligomers. The spatial and geometric arrangement is directed by the size and numbers of functional moieties of the linker molecule. Electron transmission microscopy reveal the formation of dimers, trimers and tetramers.

One-pot preparation of o-xylylene diamine and its related amines

A method for one-pot preparation of o-xylylene diamine, 1,8-diaminomethylnaphthalene, and 1,2,4,5-tetrakis(aminomethyl)benzene has been developed. The procedure is simpler and the yield of the reaction is higher than by the conventional method.
