Abstract

Настоящее изобретение относится к способу получения антибактериальных соединений, таких как хлорамфеникол и его аналоги тиамфеникол и флорфеникол, и, в частности, к новой реакции получения промежуточных соединений аминодиолфенилсульфона. Данная реакция позволяет вводить модифицированные фрагменты для получения модифицированных антибиотиков, обладающих повышенной стабильностью по отношению к действию бактериальных детерминант устойчивости. Кроме того, благодаря улучшенной процедуре можно сократить количество стадий очистки и получать продукт более высокой степени чистоты.
