Получен продукт с достаточной чистотой и выходом в экологически чистых условиях реакции. Техника микроволн превосходит традиционные подходы к термическому нагреву, ускоряет реакцию чистым и экологичным способом без использования органических или токсичных растворителей. Структурная формула продукта подтверждена кристаллографическими и спектроскопическими исследованиями. Рентгеновская дифракция монокристалла показывает, что соединение кристаллизуется в орторомбической центрально-симметричной кристаллической форме с однозначным назначением E-конфигурации для связи Сз-Cthienyi. Синтезированные молекулы имеют два центра хиральности в кольце гидроксипирролидин-2-она: 1) атом углерода, присоединенный к азоту, гидроксильная группа и фенильное кольцо; 2) атом азота, присоединенный к карбонильному углероду группы R3, хиральный углерод в кольце и ковалентная связь, несущая неподеленную пару электронов. Методом теории функционала плотности рассчитана оптимизированная геометрия молекулы, полученные результаты хорошо согласуются с экспериментальными данными. Оценка биологической и лечебной активности соединения дает результаты, аналогичные исходным данным по противоопухолевому лечению толстой кишки и груди, что может быть связано с присутствием гидроксильной группы, гетероциклов и серы. Расчет электростатического потенциала молекулы определяет местонахождение наиболее электрофильного участка рядом с гидроксильной группой, присоединенной к гетероциклическому кольцу, что согласуется с показателями биоактивности. Определены граничные молекулярные орбитали и обнаружено, что разность энергий между высшей занятой и низшей вакантной молекулярными орбиталями составляет -0.15228 эВ. Предложен механизм, в котором происходит внутримолекулярная нуклеофильная атака на карбонильный углерод неподеленной парой электронов на атоме азота, приводящий к замыканию цикла с переносом протона на кислород и окончательным образованием гидроксильной группы.</p></abstract><trans-abstract xml:lang="en"><p>A microwave-assisted, chemoselective synthesis of novel antitumor and antimicrobial (3E)-5-hydroxy-1-isopropyl-3-[(5-methyl-2-thienyl)methylene]-5-phenylpyrrolidin-2-one has been achieved via the solvent-free one-pot reaction of (3E)-3-[(5-methyl-2-thienyl)methylene]-5-phenylfuran-2(3H)-one with isopropylamine. The product is obtained in significant purity and yield under ecofriendly reaction conditions. The microwave technique surpasses conventional thermal heating approaches by accelerating the reaction in a clean, ecofriendly manner that avoids the use of organic or toxic solvents. The structural formula of the product is confirmed by crystallographic and spectroscopic characterization. X-ray single crystal diffraction reveals that the compound crystallizes in an orthorhombic centrosymmetric crystal form, with unambiguous assignment of the E-configuration for the C3-Cthienyl bond. The synthesized molecules have two centers of chirality in the hydroxypyrrolidin-2-one ring: 1) the carbon atom attached to nitrogen, the hydroxyl group, and the phenyl ring; 2) the nitrogen atom attached to the carbonyl carbon R3 group, the chiral carbon in the ring, and the covalent bond bearing the lone pair of electrons. The molecular geometry is also optimized using density functional theory calculations, and the results obtained are in good agreement with the experimental data. Evaluation of the biological and medicinal activity of the compound affords similar results to the reference data in antitumor treatment of human colon and breast cells, which can be attributed to the presence of the hydroxyl group, the heterocyclic motifs, and sulfur. Calculation of the molecular electrostatic potential locates the most electrophilic site near the hydroxyl group attached to the heterocyclic ring, which is consistent with the bioactivity results. The frontier molecular orbitals are also determined, finding that the energy difference between highest occupied molecular orbital and lowest unoccupied molecular orbital is -0.15228 eV. A mechanism is proposed in which an intramolecular nucleophilic attack occurs on the carbonyl carbon by the lone pair of electrons on the nitrogen atom, leading to ring closure with proton transfer to oxygen and final formation of the hydroxyl group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микроволна</kwd><kwd>гидроксипирролидин-2-он</kwd><kwd>реакция без катализатора и растворителя</kwd><kwd>экологичный способ</kwd><kwd>кристаллографическая характеристика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microwave</kwd><kwd>chemoselective</kwd><kwd>hydroxypyrrolidin-2-one</kwd><kwd>catalyst- and solvent-free</kwd><kwd>ecofriendly</kwd><kwd>crystallographic characterization</kwd></kwd-group><funding-group><funding-statement xml:lang="en">We thank Dr. El Sayed Shalaby (Elettra-Sincrotrone Trieste, Italy &amp; Crystallography Lab., NRC, Egypt) for the great help during X-ray diffraction data collection and crystal structure refinement.
