© 2016 Taylor & Francis Group, LLC.New phosphorylated azomethines on the basis of salicylaldehyde were obtained. These compounds react with P(Y) chlorides to form diphosphorylated azomethines

Reactions of Pyridoxal with Heterocycles Containing Primary Amino Group

© 2018, Pleiades Publishing, Ltd. New nitrogen-containing derivatives of pyridoxal were obtained as a result of its reaction with various amines. The reactions with amines bearing a heterocyclic fragment (pyridine, pyrimidine, quinoline, piperidine) furnished the final products stabilized in an aminoacetal form. The product prepared from 2-aminomethylpiperidine has an imidazolidine fragment in the molecule

The application of geoinformation systems for the purposes of economical-statistical analysis

The research article discusses possibilities of modern GIS for solving problems of socio-economic analysis of regional and urban systems, and prospects of GIS support for implementation of basic functions of regional management. The experience of geoinformation technologies adoption in operation of the regional statistical agency is analyzed. Characteristics of structuralfunctional features of the GIS, oriented on solution of statistical analysis problems of regional systems of the Volga Federal district and the Republic of Tatarstan are given. Possibilities of its GIS-maps system and spatial databases, as well as in the authors' program package for operative preparation of the economic maps series for state estimation of main functional subsystems of the region, which enable to monitor economic activities in the regional municipalities are discussed
