3-Aryl-Z-2-aroylmethylidene-1,2-dihydroquinoxalines react with oxalyl chloride to form 3-aryl-2-(2-aryl-4,5-dioxo-4,5-dihydro-3-furyl)quinoxalines, whose thermal decarbonylation generate 5-aryl-2-3(arylquinoxalin-2-yl)-4-aroyl-3-aroyloxy-1H-pyrido[1,2-a]quinoxalin-1-ones. The crystal and molecular structures of one of them (Ar = Ph) were established by X-ray diffraction analysis. 相似文献

Intramolecular cyclization of [N-benzyl(arylglyoxylimidoyl)]ketenes generated upon thermal decarbonylation of 4,5-diaroyl-1-benzylpyrrole-2,3-diones is accompanied
by redox processes to form 3-aroyl-5-aryl-4H-furo[3,2-c]isoquinolin-2-ones and 3-benzoyl-4-benzylamino-5-phenyl-5H-furan-2-one (1). The molecular and crystal structure of compound 1 was studies by X-ray diffraction analysis. Under conditions
of thermolysis, the starting pyrrole-2,3-diones are partially reduced to 4,5-diaroyl-1-benzyl-3-hydroxy-5H-pyrrol-2-ones.

Thermal decarbonylation of 3-p-toluoylpyrrolo[2,1-c][1,4]benzoxazine-1,2,4-trione affords (2-oxo-1,4-benzoxazin-3-yl)(p-toluoyl)ketene. The latter enters into the [4+2]-cycloaddition reaction withp-bromobenzylidene-p-anisidine to form 1-p-bromophenyl-2-p-methoxyphenyl-4-p-toluoyl-1,2-dihydropyrimidino[4,3-c][1,4]benzoxazine-3,5-dione. The molecular and crystal structure of the title compound was studied by X-ray diffraction analysis.

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.

Oxidation of 2-aryl-2,3-dihydro-4(1H)-quinolones (1) with 1.5 equivalents of (dichloroiodo)benzene in dichloromethane at room temperature leads to regioselective chlorination, thereby offering an efficient method for the synthesis of new 2-aryl-6-chloro-2,3-dihydro-4(1H)-quinolones (3). 相似文献

3-Alkoxycarbonylmethylene-1-phenyl-1,2,3,4-tetrahydro-2-quinoxalones, obtained by the interaction of dialkyl esters of oxaloacetic acid and N-phenyl-o-phenylenediamine, react with oxalyl chloride with the formation of 3-alkoxycarbonyl-5-phenyl-1,2,4,5-tetrahydropyrrolo[1,2-a]quinoxaline-1,2,4-triones. Alkoxycarbonyl(2-oxo-1-phenyl-1,2-dihydro-3-quinoxalinyl)ketenes, generated on thermal decarbonylation of the latter, are stabilized by participation in a [4+2] cyclodimerization reaction with the formation of 2,4-di(alkoxycarbonyl)-2-(3-oxo-4-phenyl-3,4-dihydro-2-quinoxalinyl)-6-phenyl-2,3,5,6-tetrahydro-1H-pyrido[1,2-a]quinoxaline-1,3,5-triones. The crystal and molecular structure of the di(ethoxycarbonyl) derivative have been investigated by X-ray structural analysis.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1501–1506, October, 2004. 相似文献

The cycloaddition of epoxide and CO2 to synthesize cyclic carbonate catalyzed by VO(IV) porphyrin was achieved under 1.4 MPa at 150°C. The effects of reaction temperature, time, CO2 pressure, co‐catalyst and porphyrin framework were investigated. The catalytic results showed that moderate to high yields of cyclic carbonates were obtained under the optimal reaction conditions. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

The reaction of (arylhydrazono)cyanothioacetamides with chloro ketones and phenacyl bromides was studied. The products are either thiazoles or 4,5-dihydrothiophenes, depending on the starting thioamides and halo ketones. 相似文献
