The replacement of one or more nitrogen atoms of the heterocyclic base with a CH group affords deazapurine nucleoside analogues, and the replacement of the methine group with a nitrogen atom gives azapurine derivatives. A combination of aza and deaza moieties in the purine base leads to aza(deaza)-modified bases. Some nucleoside analogues were found to exhibit pronounced anticancer and antiviral activity. The synthesis and evaluation of biological activity of aza- and deazapurine nucleoside analogues have attracted interest from researchers four decades ago. This review describes and integrates the studies concerning certain aspects of the synthesis and(or) activity of various representatives of this class of compounds. The structure–biological activity relationships are analyzed. The successful approaches to the design of aza- and deazapurine nucleoside analogues are considered. A comparison is given for the methods of chemical and enzymatic synthesis of these compounds.

The basic concepts of reticular chemistry, a new branch of science, which combines methods of synthetic chemistry with methods for topological design of polymer compounds, are considered. Reticular chemistry methods are illustrated with examples of the analysis and design of coordination polymers. The most complete classification of coordination polymers, which are similar in terms of various compositional and topological parameters, is given. This review describes and integrates information on the topological analysis tools, such as computer software and electronic databases. A special attention is paid to the application of topological methods in the machine analysis and the prediction of structures and properties of coordination polymers, in particular to the establishment of chemical composition–structure–property relationships and the development of knowledge bases and artificial intelligence systems. A procedure for the search for the general crystal-chemical features using automatic heuristic analysis of large sets of structural data is discussed. It is shown how this analysis can be used to determine the limits of applicability of reticular chemistry and the possibility of its extension to coordination polymers containing structurally, chemically and topologically complex building units with high conformational flexibility. Approaches of reticular chemistry are considered in detail in relation to the design of proton-conductive coordination polymers, which have received considerable attention in the past decade. The specific features of the topological structures of this class of compounds are described in a systematic way. The relationships between the chemical composition, structure and conductive properties of these compounds and the applicability of targeted design are discussed. The bibliography includes 303 references.","PeriodicalId":21523,"journal":{"name":"Russian Chemical Reviews","volume":"91 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59011163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The progress in this field is related to advances in the methods for generation of aryl radicals. The currently used aryl radical precursors include aryl halides, aryldiazonium and diaryliodonium salts, arylcarboxylic acids and their derivatives, arylboronic acids, arylhydrazines, organosulfur(II, VI) compounds and some other compounds. Aryl radicals are generated under mild conditions by single electron reduction or oxidation of precursors induced by conventional reagents, visible light or electric current. A crucial role in the development of the radical arylation methodology belongs to photoredox processes either catalyzed by transition metal complexes or organic dyes or proceeding without catalysts. Unlike the conventional transition metal-catalyzed arylation methods, radical arylation reactions proceed very often at room temperature and have high functional group tolerance. Without claiming to be exhaustive, this review covers the most important advances of the current decade in the generation and synthetic applications of (het)aryl radicals. Examples of reactions are given and mechanistic insights are highlighted. The bibliography includes 341 references.","PeriodicalId":21523,"journal":{"name":"Russian Chemical Reviews","volume":"90 1","pages":"116 - 170"},"PeriodicalIF":7.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59008495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
