The crystal and molecular structures of 2,10-diacetoxy-13-thiabicyclo[7.3.1]-cis-tridec-5-ene and 2,9-dichloro-13-thiablcyclo[8.2.1]-cis-tridec-5-ene sulfoxide were established. The conformations of the molecules are such that the unshared pairs of electrons of the sulfur atoms are directed to the carboncarbon double bonds of their molecules. It was observed that there are stereochemical conditions for transannular transformations under the influence of polarized molecules and cations.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1628–1632, December, 1977. 相似文献

Molar extinction coefficients of some carbohydrates viz. l-arabinose (C5H10O5), d-glucose (C6H12O6), d-mannose (C6H12O6), d-galactose (C6H12O6), d(-) fructose (C6H12O6) and maltose (C12H24O12) in aqueous solutions have been determined at 81, 356, 511, 662, 1173 and 1332 keV by gamma ray transmission method in a
narrow beam good geometry set-up. These coefficients have been found to depend upon the photon energy following a 4-parameter
polynomial. These extinction coefficients for different sugars having the same molecular formula have same values varying
within experimental uncertainty. Within concentration ranges studied, Beer-Lambert law is obeyed very well. 相似文献

Synthesis and antiadrenergic properties of β-substituted alcohols based on 6-hydroxymethylpyridoxine
R. S. Pavelyev R. R. Khairullina S. A. Koshkin A. G. Iksanova O. A. Lodochnikova N. N. Khaertdinov G. F. Sitdikova A. F. Safina E. G. Aleksandrova L. E. Ziganshina Yu. G. Shtyrlin 《Russian Chemical Bulletin》2016,65(2):519-531
An approach to the synthesis of epoxides based on 6-hydroxymethylpyridoxine acetals was developed. The epoxides obtained were involved in the ring opening reactions by nitrogen-, oxygen-, and sulfur-containing nucleophiles. Cytotoxicity and antiadrenergic properties of some synthesized compounds were studied on the models in situ and in vivo. 相似文献

The experimental data on the enthalpies of vaporization and formation of more than 30 three-coordinate arsenic derivatives of various structures were collected and analyzed. The group contributions of arsenic-containing fragments to the enthalpies of vaporization and formation were calculated. This opens up the possibility of calculating the fundamental thermochemical characteristics of a wide range of As(III) derivatives by the additive scheme. 相似文献

A new version of immunoenzyme assay for the antigens of pathogenic microorganisms Streptococcus pyogenes and Staphylococcus aureus based on the use of amperometric sensors is proposed for their determination in diagnosing infectious diseases (tonsillitis of different severities). The best conditions for sensor operation were chosen, and the quantitative characteristics of the antibodies used and the antigen–antibody immune complexes formed. The sensors developed were tested with blood serums from ill patients, and the possibility of the differential diagnostics of diseases, at the early stages of their development, in particular, was demonstrated. 相似文献
