The interaction of 5-aryl-4-quinoxaline-2,3-dihydro-2,3-furandiones with mesitylamine and methyl(phenyl) hydrazine results in the formation of 1-substituted 5-aryl-4-quinoxalinyl-2,3-dihydro-2,3-pyrrolediones. The crystal and molecular structure of the 1-mesityl-5-phenyl derivative was investigated by X-ray diffraction.Original Russian Text Copyright © 2004 by Z. G. Aliev, N. Yu. Lisovenko, L. O.

1-Unsubstituted 4,5-diphenyl-2,3-dihydro-2,3-pyrroledione interacts with ethoxycarbonyl-methylenetriphenylphosphorane regioselectively to give 4,5-diphenyl-Z-2-ethoxycarbonyl-methylene-2,3-dihydro-3-pyrrolone. The crystal and molecular structure of the latter was studied by X-ray analysis.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 8, pp. 1556–1558, August, 1995. 相似文献

Reduction of 1-alkyl-3-(2-quinolyl)quinolinium halides with sodium borohydride leads to 1-alkyl-1,2-dihydro-2,3-biquinolyls which, except for the ethoxycarbonyl derivative, undergo rearrangement to 1-alkyl-1,4-dihydro-2,3-biquinolyls. The last can be synthesized by the alkylation of the corresponding 1,4-dihydro-2,3-biquinolyls under conditions of interphase catalysis and in the system KOH-DMSO.For Communication 7, see [1].Stavropol' State University, Stavropol' 355009, Russia; nauka@stavsu.ru.

4-Isopropoxalyl-1,5-diphenyl-2,3-dihydro-2,3-pyrroledione reacts with thiosemicarbazide to form (3aS*)(4R*)(6aR*)-4,6a-dihydroxy-4-isopropoxycarbonyl-1-thiocarbamoyl-3,5-diphenyl-1,3a,4,5,6,6a-hexahydropyrrolo[3,4-d]pyrazol-6-one. The molecular and crystal structure of the latter was studied by single crystal X-ray diffraction. 相似文献

Quantum-chemical calculations and IR spectroscopy were used to study the conformations as well as the energy and spectral characteristics of 2,3-trimethylene- and 2,3-pentamethylene-3,4-dihydro-4-quinazolinones. The shift of -electron density from the heterocyclic system to the carbonyl group and, thus, the proton affinity of the oxygen atom of this group increase with expansion of the bond angle at the nitrogen atom in going from a five-membered to seven-membered ring. 相似文献

A novel perfluoromonomer, perfluoro-2,3-dihydro-1,4-benzodioxin (FDB), was synthesized. The homopolymerization and copolymerizations of FDB were investigated. The structure and physical properties of those polymers were characterized. 相似文献
