   <abstract xml:lang="ru">
    <p>Синтезировано несколько новых коротких N-ацилдипептидов, содержащих N-терминальный 4-(1-адамантил)бензоильный фрагмент, с использованием классического метода пептидного синтеза в растворе на основе N,N-карбонилдиимидазола. С помощью спектроскопии 1Н ЯМР осуществлен контроль стереохимической чистоты целевых соединений. Обнаружено, что в случае наличия асимметрического атома углерода в неконцевом аминокислотном остатке образуется смесь двух диастереомеров N-ацилдипептидов. Высказано предположение, что это связано с образованием на промежуточной стадии оптически неактивного оксазольного интермедиата. Синтезированные соединения представляют интерес в качестве потенциальных терапевтических агентов с противовирусной активностью в сочетании с низкой токсичностью.</p>

    <p>Several new short N-acyldipeptides containing the N-terminal 4-(1-adamantyl)benzoyl moiety have been synthesized using the classical peptide synthesis method in a solution based on N,N-carbonyldiimidazole. 1H NMR spectroscopy monitored the stereochemical purity of the desired compounds. It has been found that in the presence of an asymmetric carbon atom, a mixture of two diastereomers of N-acyldipeptides is formed in a non-contiguous amino acid residue. It has been suggested that this is due to the formation of an optically inactive oxazole intermediate at an intermediate stage. The synthesized compounds are of interest as potential therapeutic agents with antiviral activity in combination with low toxicity.</p>
