Аннотация: 1-Ethyl-2,3-dicyano-5-nitromethyl-6-methoxy-1,4,5,6-tetrahydropyrazine reacts with N-methylquinoxalinium iodide in the presence of triethylamine to form octahydro-2,4a,5,10-tetraazabenzo[b]fluorene-3,4-dicarbonitrile, while our attempts to obtain similar polycyclic products from stereoisomeric 5-(S)- and 5-(R)-(1`-nitroprop-1`-yl)-6-methoxy-1,4,5,6-tetrahydropyrazines derived from the reaction of 1-nitropropane with 2,3-dicyano-5,6-dimethoxy-1-ethyl-1,4,5,6-tetrahydropyrazine.

    Reactions of radicals generated from 1-ethyl-1,4-diazinium salts: Addition to the C-C triple bond versus dimerization [Text] / G. L. Rusinov, E. V. Verbitskiy, P. A. Slepukhin, O. N. Zabelina, M.

Аннотация: Radical species generated from 5-aryl-substituted 1-ethyl-2,3-dicyano-1,4-diazinium salts by action of sodium iodide undergo dimerization into [2,2?]bipyrazinyl derivatives, as evidenced by NMR and X-ray crystallography data. The pyrazinyl radicals can also be involved into the addition reaction on the C-C triple bond, thus demonstrating a new synthetic route to modify the structure of pyrazines. The structures of E- and Z-isomers of 1-(1?,2?-dihydropyrazinyl-2?)-2-iodoethenes have been proved by 1H and 13C NMR spectroscopy and X-ray analysis

Аннотация: Stable delta(H)-adducts of O- and C-nucleophiles were obtained with cations of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium, and their structure was investigated by X-ray diffraction analysis. Analytical separation was performed of 1,2-dihydropyrazines into individual enantiomers by means of HPLC on columns with chiral sorbents

Аннотация: C-Adducts of 5-(het)aryl-2,3-dicyano-1-pyrazinium salts containing a residue of a 1,3-dicarbonyl compound at position 6 can be involved in the cyclization with hydrazine hydrate giving rise to pyrazino[2,3-c]pyridazines along with the expected pyrazole derivatives. The reactions of the same ?H-adducts with hydroxylamine unexpectedly afforded triazacyclopenta[a]indene derivatives. The crystallographic data on the three-dimensional structures of new polycyclic compounds were obtained
