To synthesize tertiary amines containing gem-dichlorocyclopropane or 1,3-dioxolane fragmentusing the Mannich reaction, as well as obtain ethyl ester of β-aminopropionic acidbydecarboxylation of tert-amine, a derivative of diethylmalonate containing a gem- dichlorocyclopropane fragment.Methods. In order to obtain tertiary amines by the Mannich reaction, the microwave activation method was used. To determine the qualitative and quantitative composition of the reaction masses, gas chromatography, electron ionization mass spectrometry, and 1H-, 13C-nuclear magnetic resonance spectrometry methodswere used.Results. Under microwave radiationconditions, tertiary amines containing gem- dichlorocyclopropane or 1,3-dioxolane fragment were synthesized by condensation of secondary amines, CH-acids, and paraformaldehyde.Conclusions. Tertiary amines containing a gem-dichlorocyclopropane or cycloacetal fragment in their structure were obtainedin high yields under microwave radiation.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. Синтезировать по реакции Манниха третичные амины, содержащие гем-дихлорциклопропановый или 1,3-диоксолановый фрагмент, а также получить этиловый эфир β-аминопропионовой кислоты декарбоксилированием трет-амина – производного диэтилмалоната, содержащего гем-дихлорциклопропановый фрагмент.Методы. Для получения третичных аминов по реакции Манниха был использован метод микроволной активации. Для определения качественного и количественного состава реакционных масс были использованы следующие методы анализа: газовая хроматография, масс-спектроскопия с электронной ионизацией, и 1H-, 13C-спектроскопия ядерного магнитного резонанса.Результаты. Третичные амины, содержащие гем-дихлорциклопропановый или 1,3-диоксолановый фрагмент, синтезированы конденсацией вторичных аминов, СН-кислот и параформальдегида в условиях микроволнового излучения.Выводы. С высокими выходами в условиях микроволнового излучения получены третичные амины, содержащие в своем строении гем-дихлорциклопропановый или циклоацетальный фрагмент.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вторичные амины</kwd><kwd>СН-кислота</kwd><kwd>микроволновое излучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>secondary amines</kwd><kwd>CH-acid</kwd><kwd>microwave radiation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при финансовой поддержке программы «Приоритет 2030».</funding-statement><funding-statement xml:lang="en">The study was supported by the Priority 2030 program.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кузьмина У.Ш., Раскильдина Г.З., Ишметова Д.В.
