Abstract

A process for the preparation of 3-monoesters of rosamycin derived from carboxylic acids, characterized in that a rosmarinic 3,2'-diester is solvolized in a medium comprising an organic solvent miscible with water until the 2'-ester group it is selectively separated and because the 3-monoester thus obtained is isolated in free form or in the form of its acid addition salt.
