A novel, two-step synthesis of 4-pyridone-3-carboxamides from 2-cyano-4-pyrones

Reactions of 2-cyano-6-(trifluoromethyl)-4-pyrone, 2-cyano-4-pyrone, and 2-cyano-6-methyl-4-pyrone with aliphatic and aromatic amines in ethanol at -20 C for 2-21 days gave 5-amino-3-oxopent-4-enamides in 28-78% yields, which were cyclized with DMF-DMA in toluene under ambient conditions to afford 4-pyridone-3-carboxamides in 31-70% yields. © 2013 Elsevier Ltd.

THE ASSESSMENT OF CLIMATE CHANGE AND WATERSHED EFFECT ON THE HETEROTROPHIC METABOLISM IN THE LAKE ONEGO ECOSYSTEM

Lake Onego, as one of the largest water bodies in a humid zone, is the recipient of terrestrial carbon and plays an important role in the global balance of this element. Due to heterotrophic metabolism in the Lake Onego ecosystem, substantial emissions of carbon dioxide from this lake into the atmosphere can be assumed. However, the extent of this phenomenon is still poorly known. As a climate change has led to an increase in water and organic matter flow into the northern water bodies, the carbon balance study of aquatic ecosystems is of particular relevance. The elements of the water balance for the Lake Onego catchment area in the current climate conditions are assessed. Based on satellite images the model of Lake Onego watershed terrestrial ecosystems is used to simulate the flow of organic matter into the lake with different types of vegetation and topography consideration. The assessment of the benthic communities habitat is carried out taking into account the accumulation of organic matter in various parts of Lake Onego

Deep wells in monitoring of geological and geodynamic processes

© SGEM2015. The authors conducted monitoring studies using core and geophysical data on a number of deep wells that penetrated the crystalline basement in the eastern portion of the Russian Plate. Information on the deep structure of the Earth's interior was mainly obtained through geophysical studies that provided data for the construction of various structural depth models. Explicit data obtained through the study of core material from deep and ultra-deep wells can be of great importance. The new methods of studying the deep horizons of the Earth's crust can give more information about the geological and geodynamic processes in zones that were previously thought to be geodynamically stable. The character of geodynamic processes can be analysed through the creation of deep geo-observatories based on deep and ultra-deep wells. Results showed that the crystalline basement undergoes extensive geodynamic and hydrothermal changes mainly within specific mobile zones of the Earth's deep crust

Leading material complexes of the crystalline basement of the tatar arch (East of the Russian plate) in the formation of weathering crust

© SGEM2016.Conducting of quantitative mineralogical analysis of metamorphic rocks penetrated by deep wells in the territory of the South-Tatar arch (East of the Russian Plate) provided an opportunity to examine and identify the leading formational types of rocks or metamorphic formations. According to the results of long-term mineralogical and petrographic research, followed by petrochemical analysis, the rocks have been grouped into two major formations. The first one – mafic-silicate formation is characterized by a predominance of mafic and mafic-silicic rock complexes. Ortho and clinopyroxene, amphibole and biotite are leading femic minerals. The second formation – high-alumina formation is characterized by a wide development of cordierite, sillimanite, garnet, biotite. The content of pyroxene, amphibole among the rocks of this formation is reduced dramatically. Leucocratic mineral component of these two formations is the same. However, the relation between minerals within the formation is different. Formation of buried weathering crust is located on the border of the sedimentary cover and the surface of crystalline basement. It was found that the material composition of the weathering crust is associated with mineralogical and petrographic features of leading metamorphic complexes. The mineral composition of weathered rocks, peculiarities of the development of finely dispersed and clay minerals in various areas of the crystalline basement are also variable and related to the original composition of the substrate in the studied territory
