A one-pot procedure for the preparation of substituted quinolines from substituted o-nitrotoluenes with electron-withdrawing groups and olefins (acrylic esters and acrylonitriles) using a cesium catalyst under mild reaction conditions is reported. The process involves a [2+4] cycloaddition mechanism.

Sequential Reduction

An efficient iron/acetic acid system-mediated reductive cyclization reaction of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes for the synthesis of 6-aryl-6H-chromeno[3,4-b]quinolines was developed. This reaction involves the sequential reduction, hydrolysis, aldol condensation, intramolecular addition, and the nucleophilic addition of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes to give the corresponding 6H-chromeno[3,4-b]quinolines. This transformation provides a straightforward synthetic protocol for constructing substituted 6H-chromeno[3,4-b]quinoline derivatives. The structures of three typical products were confirmed by X-ray crystallography.

Special Meaning

This article is dedicated to one of the patterns in development of Russian colloquialism – reconsideration of the key meaning of casual words through metaphorization and metonymization. The goal of this work consists in examination of the trend inherent to Russian colloquialism throughout its evolution, which consists in transferring the meaning of casual words for their use in the field of term formation, as well as in analysis of this phenomenon from the perspective of a Vietnamese native speaker. The article studies the prerequisites that contribute to active use of the colloquialism in formation of special terminology; describes the process of transformation of the meaning of casual words for creating a new terminological meaning; considers the possibilities of formation of special meaning of casual words using metaphors and metonymy. The theoretical framework of this research is comprised of the works of Russian and Vietnamese linguists on reconsideration of colloquialism in term formation. Terms from the various academic fields served as the material for this research. The scientific novelty lies in interpretation of reconsideration of colloquialism as the most economical method for enriching Russian language vocabulary via potential of lexical unites present therein. Practical significance of this study is substantiated by the fact that the acquired results can be used in preparing special curricula, educational materials on lexicology, as well as in teaching Russian language as foreign to Vietnamese audience.
