   <abstract xml:lang="ru">
    <p>В работе рассмотрены вопросы, касающиеся реакции размыкания (раскрытия) экзоцикла в молекулах форбинов (на примере метилфеофорбида а) при действии O-нуклеофилов – воды и спиртов. Показано, что даже такие относительно слабые нуклеофилы, как вода и спирты, способны в определённых условиях приводить к размыканию экзоцикла в молекуле метилфеофорбида а с образованием производных хлорина е6. Изучение данной реакции, помимо прочего, открывает новые синтетические пути к получению эфиров хлорина е6 различной степени замещения, а в конечном итоге – и свободного хлорина е6 в виде трикислоты, являющегося ценным фотосенсибилизатором для фотодинамической терапии (ФДТ) и исходным соединением для получения других фотосенсибилизаторов. Рассмотрены также возможные синтетические подходы к получению свободного хлорина е6.</p>

    <p>The article considers issues concerning the reaction of exocycle opening in phorbin molecules (on the example of methylpheophorbide a) under the O nucleophiles - water and alcohols action. According to the author, under certain conditions relatively weak nucleophiles as water and alcohols can cause the opening of the exocycle in the molecule of methylpheophorbide a with the formation of chlorine derivatives e6. The study of this reaction, in addition, reveals new synthetic methods to obtain chlorine e6 esters of different degrees of substitution, and eventually - free chlorine e6 in the form of triacids. Free chlorine is a valuable photosensitiser for photodynamic therapy (PDT), and a starting compound for the preparation of other photosensitizers. The article also discusses possible synthetic approaches to obtain free chlorine e6.</p>
