The work set out to obtain cyclic tert-amines by alkylation of dimethylaminopropylamine (DMAPA) and aminoethylpiperazine (AEP) with cis-1,4-dichloro-2-butene and cis-2,3-di(chloromethyl)-gem-dichlorocyclopropane. Quaternary ammonium salts were synthesized from a cyclic amine base and the resulting compounds evaluated as substances influencing the hemostasis process. The effect of structural fragments in the resulting substances on their anticoagulation and antiplatelet properties was evaluated.</p></sec><sec><title>Methods</title><p>Methods. The target compounds were obtained by a classical method of organic synthesis: by alkylation of DMAPA and AEP with cis-1,4-dichloro-2-butene and cis-2,3-di(chloromethyl)-gem-dichlorocyclopropane. The qualitative and quantitative compositions of the reaction mixtures were determined by chromatography with a Khromatek-Kristall 5000M chromatograph fitted with a 30 m × 0.25 mm × 0.5 μm capillary column containing 5% phenyl/95% polydimethylsiloxane as the stationary phase, as well as by nuclear magnetic resonance spectroscopy using a Bruker AM-500 spectrometer having operating frequencies of 500 and 125 MHz.</p></sec><sec><title>Results</title><p>Results. The corresponding tertiary amines were obtained upon heating with 70–88% yield by alkylation of DMAPA and AEP with cis-1,4-dichloro-2-butene and cis-2,3-di(chloromethyl)-gem-dichlorocyclopropane. It was determined that the synthesized amines react with benzyl bromide to form salts with a yield of more than 80%. Quaternary ammonium salts were found to exhibit anticoagulation activity at the level of the reference standard, acetylsalicylic acid, and the highest activity is demonstrated by the amide 1-benzyl-4-[2-(2,5-dihydro-1H-pyrrol-1-yl)ethyl]piperazine. Analysis of the structure–property relationship showed that, in the series of DMAPA derivatives, the presence of a benzyl group increases the antiplatelet activity (the value of the maximum amplitude of platelet aggregation), whereas for the AEP derivatives, the presence of a benzyl group reduces by more than half the maximum amplitude of platelet aggregation, thereby reducing antiplatelet activity.</p></sec><sec><title>Conclusions</title><p>Conclusions. DMAPA and AEP condense with cis-1,4-dichloro-2-butene and cis-2,3-di(chloromethyl)-gem-dichlorocyclopropane to form the corresponding spirocyclic derivatives with high yields. The resulting amines are shown to undergo a quaternization reaction under thermal heating to form quaternary ammonium salts. The synthesized salts are found to exhibit anticoagulation activity comparable to that of the acetylsalicylic acid reference standard.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. Получить циклические трет-амины алкилированием N,N-диметилпропилендиамина и N-аминоэтилпиперазина цис-1,4-дихлорбутеном-2 и цис-2,3-дихлорметил-гем-дихлорциклопропаном; синтезировать на основе циклических аминов четвертичные аммонийные соли и оценить полученные соединения в качестве веществ, влияющих на процесс гемостаза; определить влияние структурных фрагментов в полученных веществах на их антикоагуляционные и антиагрегационные свойства.</p></sec><sec><title>Методы</title><p>Методы. Целевые соединения были получены классическим способом органического синтеза — алкилированием N,N-пропилендиамина и N-аминоэтилпиперазина цис-1,4-дихлорбутеном-2 и цис-2,3-дихлорметил-гем-дихлорциклопропаном. Для определения качественного и количественного состава реакционных масс были использованы следующие методы анализа: хроматография («Хроматэк-Кристалл 5000М» с капиллярной колонкой 30 м × 0.25 мм × 0.5 мкм, содержащей 5% фенил и 95% полидиметилсилоксан в качестве неподвижной фазы), спектроскопия ядерного магнитного резонанса (прибор «BrukerAM-500» с рабочими частотами 500 и 125 МГц).</p></sec><sec><title>Результаты</title><p>Результаты. Получены при нагревании соответствующие третичные амины с выходом 70–88% алкилированием N,N-диметилпропилендиамина и N-аминоэтилпиперазина цис-1,4-дихлорбутеном-2 и цис-2,3-дихлорметил-гем-дихлорциклопропаном. Определено, что синтезированные амины реагируют с бромистым бензилом с образованием солей с выходом более 80%. Установлено, что четвертичные аммониевые соли проявляют антикоагуляционную активность на уровне эталона — ацетилсалициловой кислоты, причем наибольшей активностью обладает амид 1-бензил-4-[2-(2,5-дигидро-1Н-пиррол-1-ил)этил]пиперазин. Анализ зависимости «структура-свойство» показал, что в ряду производных N,N-диметилпропилендиамина наличие бензильной группы повышает антиагрегационную активность (значение максимальной амплитуды агрегации тромбоцитов), тогда как для производных N-аминоэтилпиперазина наличие бензильной группы способствует снижению максимальной амплитуды агрегации тромбоцитов более чем в 2 раза, тем самым уменьшая антиагрегационную активность.</p></sec><sec><title>Выводы</title><p>Выводы. N,N-диметилпропилендиамин и N-аминоэтилпиперазин конденсируется с цис-1,4-дихлорбутеном-2 и цис-2,3-дихлорметил-гем-дихлорциклопропаном с образованием соответствующих спироциклических производных с высокими выходами. Показано, что полученные амины вступают в реакцию квартенизации в условиях термического нагрева образованием четвертичных аммонийных солей. Найдено, что синтезированные соли проявляют антикоагуляционную активность на уровне эталона — ацетилсалициловой кислоты.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>N</kwd><kwd>N-диметилпропилендиамин</kwd><kwd>N-аминоэтилпиперазин</kwd><kwd>цис-2</kwd><kwd>3-дихлорметил-гем-дихлорциклопропан</kwd><kwd>кватернизация</kwd><kwd>гемостаз</kwd><kwd>коагуляция</kwd><kwd>агрегация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dimethylaminopropylamine (DMAPA)</kwd><kwd>aminoethylpiperazine (AEP)</kwd><kwd>cis-1</kwd><kwd>4-dichloro-2-butene</kwd><kwd>cis-2</kwd><kwd>3-di(chloromethyl)-gem-dichlorocyclopropane</kwd><kwd>quaternization</kwd><kwd>hemostasis</kwd><kwd>coagulation</kwd><kwd>platelet aggregation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации в сфере научной деятельности, номер для публикаций FEUR – 2025-0001 «Нефтехимические реагенты, добавки и материалы».</funding-statement><funding-statement xml:lang="en">This work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation in the field of scientific activity, publication number FEUR – 2025-0001 “Petrochemical reagents, additives, and materials.”</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">Waiker D.K., Verma A., Akhilesh G.T., Singh N., Roy A., Dilnashin H., Tiwari V., Trigun S.K., Singh S.P., Krishnamurthy S., Lama P., Davisson V.J., Shrivastava S.K.
