With the growing resistance of pathogenic microorganisms to antibiotics, the development of new antimicrobial drugs offering specific mechanisms of action becomes an urgent task. Only few antimicrobials offer a broad spectrum of activity against gram-positive and gram-negative bacteria, molds, and yeasts. In this regard, the purpose of the work was to develop methods for synthesizing biologically active derivatives of alkyl-substituted phenols (reactions at the hydroxy group) to study their biological effect.</p></sec><sec><title>Methods</title><p>Methods. The synthesis of imidazole acetates of substituted phenols was carried out in two stages. At the first stage, the chloroacetyl derivative of the selected compounds was obtained, to which imidazole was then added. O-acylation reactions at the first stage of the synthesis were carried out under varying conditions. The first version of the synthesis was carried out using chloroacetyl chloride as an acylating agent together with a high-boiling solvent. In the second variant, chloroacetic anhydride was used, along with an attempt to replace the solvent with a low-boiling one. A thymol methoxy derivative was additionally synthesized by a known method using methyl iodide and varying the reaction parameters.</p></sec><sec><title>Results</title><p>Results. The parameters of chloroacetylation and methoxylation of aromatic alcohols were optimized with rational selection of solvents and the ratio of reagents in the reactions. Synthesized thymol (2-isopropyl-5-methylphenol) and propofol (2,6-isopropylphenol) derivatives contained imidazole as an additional pharmacophore with affinity for microorganism cell membrane proteins. A thymol methoxy derivative comprising an aromatic ether exhibiting increased hydrophobicity was also obtained. The synthesized compounds were characterized by NMR spectroscopy.</p></sec><sec><title>Conclusions</title><p>Conclusions. Chloroacetyl derivatives of aromatic alcohols can be effectively synthesized by cooling the reaction mixture using an excess quantity of an acylating agent and increasing the reaction time (compared to literature data). The yield of thymol chloroacetate was 75%, while that of propofol chloroacetate was 30%. This can be explained by the sterically hindered reaction of the propofol alcohol group, which has isopropyl substituents at the second and sixth positions of the benzene ring.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. В связи с растущей резистентностью патогенных микроорганизмов к антибиотикам актуальной задачей является разработка новых противомикробных препаратов с уникальным механизмом действия. Немногие антимикробные препараты обладают широким спектром действия на грамположительные и грамотрицательные бактерии, плесени и дрожжи. В связи с этим, цель нашей работы – разработать способы синтеза биологически активных производных алкил-замещенных фенолов (реакций по гидроксигруппе) для исследования их биологического действия.</p></sec><sec><title>Методы</title><p>Методы. Синтез имидазолацетатов замещенных фенолов проводился в две стадии. На первой стадии было получено хлорацетильное производное выбранных соединений, к которому далее присоединялся имидазол. Реакции O-ацилирования на первой стадии синтеза проводились в различных условиях. Первый вариант синтеза проводили с использованием хлорацетилхлорида в качестве ацилирующего агента и высококипящего растворителя. Во втором варианте использовали хлоруксусный ангидрид, и была предпринята попытка заменить растворитель на низкокипящий. Также было синтезировано метоксипроизводное тимола по известной методике, с применением метилйодида и варьирования параметров реакции.</p></sec><sec><title>Результаты</title><p>Результаты. Проведена оптимизация параметров хлорацетилирования и метоксилирования ароматических спиртов. Осуществлен подбор растворителей и соотношения реагентов в реакциях. Были синтезированы производные тимола (2-изопропил-5-метилфенола) и пропофола (2,6-изопропилфенола), содержащие имидазол в качестве дополнительного фармакофора, имеющего сродство к белкам клеточных мембран микроорганизмов. Также было получено метоксипроизводное тимола – ароматический простой эфир с повышенной гидрофобностью. Синтезированные соединения были охарактеризованы методом ЯМР-спектроскопии.</p></sec><sec><title>Выводы</title><p>Выводы. Синтез хлорацетильных производных ароматических спиртов при охлаждении реакционной массы с использованием избытка ацилирующего агента и увеличением времени реакции (по сравнению с литературными данными) является более предпочтительным. Выход хлорацетета тимола составил 75%, хлорацетата пропофола – 30%, что можно объяснить стерически затрудненным реагированием спиртовой группы пропофола, имеющего изопропильные заместители по 2 и 6 положениям бензольного кольца.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>алкил-замещенные фенолы</kwd><kwd>имидазол</kwd><kwd>тимол</kwd><kwd>пропофол</kwd><kwd>хлорацетат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alkyl-substituted phenols</kwd><kwd>imidazole</kwd><kwd>thymol</kwd><kwd>propofol</kwd><kwd>chloroacetate</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта Министерства науки и высшего образования Российской Федерации (проект № 0706-2020-0019) с использованием оборудования ЦКП РТУ МИРЭА</funding-statement><funding-statement xml:lang="en">The work was supported by a grant from the Ministry of Science and Higher Education of the Russian Federation (project No. 0706-2020-0019) using the equipment of the RTU MIREA Center for Collective Use</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">Hoq M.I., Mitsuno K., Tsujino Y., Aoki T., Ibrahim, H.R.
