The alkylation and acylation of 1,2,3,4-tetrahydro-4-methylspiro[quinoline-2-cyclohexane] and its bromo (methyl) derivatives substituted in the benzene ring, as well as 1,2,3,4-tetrahydro-4-methylspiro[benzo(h)quinoline-2-cyclohexane], were studied. It was established that the N-allyl derivatives ofspiro[tetrahydroquinolinecyclohexanes] are converted to their 8-allyl-substituted analogs by the action of sulfuric acid, boron trifluoride etherate, and aluminum chloride. It was shown that the N-acyl-substituted spiro[tetrahydroquinolinecyclohexanes] are recyclized to spiro[indan-1-cyclohexanes] in phosphoric acid.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 789–796, June, 1993. 相似文献

The reaction of 2,4-dichloro-6-diazoacetylpyrimidine with sodium azide to give 2,4-diazido-6-diazoacetylpyrimidine has been examined, and the crystal structure of the latter, and its 1,3-dipolar cycloadditions at the carbonyl group, studied.For Communication 6, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 515–519, April, 1990. 相似文献

[3+2]-Cycloaddition of 2-methoxycarbonylmethylene-5-phenyl-2,3-dihydro-3-furanone to acetone azine has been studied. This results in a monospirocycloadduct,viz., 9,9-dimethyl-6-methoxycarbonyl-2-phenyl-1-oxa-7,8-diazaspiro[4.4]nona-2,6-dien-4-one. Its structure has been confirmed by X-ray diffraction analysis.For the previous communication see Ref. 1.Translated fromIzvestiya Akademii Nauk.

The reactions of N-arylthiopicolinamides (HL) with copper(II) and nickel(II) ions in organic and aqueous-organic solutions were studied. On addition of HCl, the transformation of ML2 complexes into M(HL)Cl2 occurs, while the reverse reaction takes place under the action of amphoteric protic solvents. The structures of the isolated complexes were established by IR and UV spectroscopy.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 9, pp. 1546–1550, September, 1993. 相似文献

ESR and UV spectra of a binuclear complex [n-(C4H9)4N]3 CrMoOCl9 in solution and supported on SiO2 have been studied. Upon fixing this complex followed by oxidation-reduction treatment, a highly disperse state is observed, as evidenced by the ESR spectra of the Cr3+ ions.

The reaction between methyl 2-diphenylmethylenehydrazino-4-oxo-4-p-tolyl-2-butenic ether and oxalyl chloride gave 1-diphenylmethyleneamino-5-methoxycarbonyl-4-p-toluoyl-2,3-dihydro-2,3-pyrroledione, which adds water to yield substituted 3,5-dihydroxy-2,5-dihydro-2-pyrrolone. The crystal and molecular structure of pyrrolone and the inter- and intramolecular hydrogen bonds in its crystals and solutions were investigated by IR spectroscopy and XRD analysis. The crystals of C27H22N2O6 are triclinic with cell dimensions a = 9.8540(10), b = 10.0880(10), c = 13.982(2) , = 69.820(10), = 110.57(10), = 91.350(10)°, V = 1213.8(2) 3, M = 470.47, d
calc = 1.287 g/cm3, Z = 2, space group P1. The data were collected on a KM-4 (KUMA DIFFRACTION) diffractometer, 3781 reflections with I> 2 (I). Direct methods, hydrogen atoms localized, least-squares refinement (in an anisotropic approximation for non-hydrogen atoms), R = 0.0454. The crystal is built from the centrosymmetric dimer associates of molecules bonded by strong (2.64 ) intermolecular hydrogen bonds (IMHB) of O–H...O type. The dimer associates are linked by weaker (2.82 ) centrosymmetric IMHB, forming an infinite chain of hydrogen-bonded molecules. 相似文献

In the case of three isomers (, , and ) of 1-ethyl-2,5-dimethyl-4-phenyl-4-piperidinol it is shown that NOESY spectroscopy can be successfully used in the determination of the orientation of the phenyl substituent. It was observed that the chemical shifts of the protons and the carbon atoms in the ortho position and of the quaternary C atom of the phenyl substituent and the
, direct spin-spin coupling constant (SSCC) satisfactory reflect the change in the orientation of the phenyl substituent on passing from the a isomer to the and isomers. A chair 2a5e) twist-boat (2e, 5e) conformational equilibrium in which the twist-boat conformation is stabilized by an intramolecular hydrogen bond is proposed for the isomer of 1,2,5-trimethyl-4-phenyl-4-piperidinol on the basis of the NMR data.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1069–1072, August, 1990. 相似文献
