Endic acid imides were synthesized by direct fusion of endic anhydride with various amino acids. Further transformations of the resulting acids gave new 2,3-dienoic acids containing a norbornene fragment. Triphenylphosphine-catalyzed [3+2]-cycloaddition of the latter to fullerene C60 afforded the corresponding cyclopentenofullerenes.

Cyclic brush polymers represent an exciting new macromolecular topology. For the first time, this new topology has been combined with metallo-supramolecular interactions to construct novel cyclic brush polymers. Here, ring-expansion metathesis polymerization was used to synthesize a universal cyclic template with a polynorbornene backbone, which was further modified with the metal-chelating synthon terpyridine. The terpyridine side chains served as the key supramolecular unit for the creation of cyclic polymer brushes and gels. This metallo-supramolecular functionality allowed direct visualization of the cyclic brush polymers by transmission electron microscopy for the first time. This demonstration should open a new area in which supramolecular interactions are used to build an array of novel cyclic brush copolymers as well as other cyclic-polymer-based architectures generating new materials.

Cycloaddition reaction of 2,5-bis(trifluoromethyl)-1,3,4-oxadiazole with strained olefinic bonds of norbornenes was used to synthetize functionalized polynorbornanes. This simple, one step procedure was more effective when reaction was carried out by clas
Features of reactions between (3,5-dioxo-4-azatricyclo-[5.2.1.0 2-endo,6-endo ]dec-8-en-4-yl)carboxylic acids and p-nitrophenyl azide

Reactions were performed of (3,5-dioxo-4-azatricyclo[5.2.1.0 2-endo,6-endo ]dec-8-en-4-yl)carboxylic acids and their derivatives with p-nitrophenyl azide. A significant fact of the involvement of the carboxy group into the formation of aziridine ring was established and the intermolecular character of this process was confirmed. The structure of compounds synthesized was proved by IR and 1H NMR spectra.
