Procedure for the obtaining of formula tilosine derivatives (I), in which r is one of various types of radicals; and r is hydroxyl or alcanoiloxi. It consists of the reaction of a compound of formula (II), in which r is a protected aldehyde group; and r "and r" may be several types of radicals, with substituted bencilsulphonic acid or a reactive reagent of themselves; following reaction with an alkaline metallic halide; reaction with trisused tumor hydride; and separation of the group protector of the aldehido group. These compounds have pharmacological applications as macrolidicos antibiotics. (Machine-translation by Google Translate, not legally binding)
