COMPETITIVENESS AND AGONALITY IN MODERN SPORTS

The relevance of the research is associated with negative trends in modern sports: a departure from the ethical principles of fair play, the commercialization of sports and its transformation into an instrument of political influence. The article is devoted to the analysis of intuitively similar, but different in content concepts related to sports activities and underlying ethical principles. The purpose of the article is a semantic analysis of the concepts of “competitiveness” and “agonality”. The material for the study was scientific and methodological publications on the topic of the study, available in the public domain. The lexico-semantic method was used in the analysis of the material. The results of the study showed that these concepts differ significantly from each other. Thus, competitiveness defines the essence of sport as, first of all, competitive activity, and ensures the achievement of the maximum possible sports results. Competitiveness can be considered as a principle of organization of competitive activity, providing for equality of starting opportunities of competitors. Agonality is understood as a competition organized according to certain rules, based on one’s own worldview, realizing a competitive desire in a person and having a non-gaming character. It is the latter that makes this concept not applicable to the characteristics of modern sports, one of the characteristics of which is entertainment. Scope of application of the results: understanding the essence of the concepts considered makes it possible to better understand the principles, mechanisms and content of sports activity

Protic Ionic Liquid as Reagent, Catalyst, and Solvent: 1-Methylimidazolium Thiocyanate

We propose a new concept of the triple role of protic ionic liquids with nucleophilic anions: a) a regenerable solvent, b) a Brønsted acid inducing diverse transformations via general acid catalysis, and c) a source of a nucleophile. The efficiency of this strategy was demonstrated using thiocyanate-based protic ionic liquids for the ring-opening of donor-acceptor cyclopropanes. A wide variety of activated cyclopropanes were found to react with 1-methylimidazolium thiocyanate under mild metal-free conditions via unusual nitrogen attack of the ambident thiocyanate ion on the electrophilic center of the three-membered ring affording pyrrolidine-2-thiones bearing donor and acceptor substituents at the C(5) and C(3) atoms, respectively, in a single time-efficient step. The ability of 1-methylimidazolium thiocyanate to serve as a triplex reagent was exemplarily illustrated by (4+2)-annulation with 1-acyl-2-(2-hydroxyphenyl)cyclopropane, epoxide ring-opening and other organic transformations

Pedagogical management of the quality of training for a physical culture specialist in higher school: An expectation approach to the problem

The paper is devoted to the problem of pedagogical management of the quality of training for physical education specialists in higher education: the authors have determined theoretical and methodological foundations of the problem, a conceptual model and pedagogical conditions for its implementation have been presented. The authors of the paper have proved that professional expectations are a construct that anticipates actions aimed at building professional competence, but at the same time it is a product of the processes of mastering the education content. The expectation approach suggests considering the pedagogical management of the quality of training for specialists in physical education at a pedagogical university as a process of changing and shaping professional expectations of the subject of the educational process. In our study, the expectation approach is based on the conceptual ideas of the axiological, competence, and integrative constituent elements. The identified axiological, competence, and integrative constituent elements of the expectation approach determine the multilevel and hierarchical nature of the theoretical and methodological fundamentals of pedagogical management of the quality of training for physical education specialists including the general scientific, concrete scientific, methodological and technological levels of the methodology

Convenient Synthesis of Functionalized Cyclopropa[c]coumarin-1a-carboxylates

A simple method has been developed for the synthesis of cyclopropa[c]coumarins, which belong to the donor-acceptor cyclopropane family and, therefore, are promising substrates for the preparation of chromene-based fine chemicals. The method, based on the acetic acid-induced intramolecular transesterification of 2-arylcyclopropane-1,1-dicarboxylates, was found to be efficient for substrates containing hydroxy group directly attached to the aromatic ring

Synthesis of (Het)aryl 2-(2-hydroxyaryl)cyclopropyl Ketones

A simple general method for the synthesis of 1-acyl-2-(ortho-hydroxyaryl)cyclopropanes, which belong to the donor–acceptor cyclopropane family, has been developed. This method, based on the Corey–Chaykovsky cyclopropanation of 2-hydroxychalcones, allows for the preparation of a large diversity of hydroxy-substituted cyclopropanes, which can serve as promising building blocks for the synthesis of various bioactive compounds

Kinetics and Mechanism of Synthesis of Carboxyl-Containing N-Vinyl-2-Pyrrolidone Telehelics for Pharmacological Use

It was found that sulfanylethanoic and 3-sulfanylpropanoic acids are effective regulators of molecular weight with chain transfer constants of 0.441 and 0.317, respectively, and show an unexpected acceleration effect on the radical polymerization of N-vinyl-2-pyrrolidone, initiated by 2,2’-azobisisobutyronitrile. It was determined for the first time that the thiolate anions of mercapto acids form a high-temperature redox initiating system with 2,2’-azobisisobutyronitrile during the radical polymerization of N-vinyl-2-pyrrolidone in 1,4-dioxane. Considering the peculiarities of initiation, a kinetic model of the polymerization of N-vinyl-2-pyrrolidone is proposed, and it is shown that the theoretical orders of the reaction rate, with respect to the monomer, initiator, and chain transfer agent, are 1, 0.75, 0.25, and are close to their experimentally determined values. Carboxyl-containing techelics of N-vinyl-2-pyrrolidone were synthesized so that it can slow down the release of the anticancer drug, doxorubicin, from aqueous solutions, which can find its application in the pharmacological field

Lewis Acid Triggered Vinylcyclopropane–Cyclopentene Rearrangement

We report a mild Lewis acid induced isomerization of donor–acceptor cyclopropanes, containing an alkenyl moiety and diverse electron-withdrawing group(s) at the adjacent positions, into substituted cyclopentenes. We have found that 1,1,2-trisubstituted cyclopent-3-enes were exclusively obtained in yield of 51–99% when cyclopropanes with a 2-substituted alkenyl group as a donor underwent isomerization. For cyclopropanes bearing a trisubstituted alkenyl group either the corresponding cyclopent-3-enes or isomeric cyclopent-2-enes having two acceptor groups at the C(1) atom were formed, with the reaction selectivity being determined by the applied Lewis acid. We have shown that the reactivity of the donor–acceptor cyclopropane increases with the increase of the electron-donating character of (hetero)­aromatic group attached to the alkenyl moiety. The synthetic utility of the developed methodology was also demonstrated through the synthesis of polysubstituted cyclopentane and piperidine derivatives
