Установлено, что в реакциях ацилирования гидроксильная группа изоликвиритигенина в положении 2, менее реакционноспособна, чем в положениях 4 и 4,. Изоликвиритигенин и его производные со свободной 2,-гидроксильной группой подвергаются циклоизомеризации в условиях газохроматографического анализа.</p></abstract><trans-abstract xml:lang="en"><p>Derivatives of resveratrol and isoliquiritigenin (esters of acetic, benzoic and succinic acid) have been synthesized and characterized. The hydroxy group in 2,-position of isoliquiritigenin is acylated more readily than at positions 4 and 4, that can be explained by the influence of the intramolecular hydrogen bond. Isoliquiritigenin and its derivatives with free 2,-hydroxyl undergo cycloisomerisation during gas chromatography analysis.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Барабой В.
