A process is disclosed for the aromatic sulfonylation, sulfenylation, thiocyanisation and phosphorylation of cyclic depsipeptides with 6 to 24 ring atoms, composed of .alpha.-hydroxycarboxylic acids and .alpha.-aminoacids and containing at least one phenyl residue. The process is characterised in that said cyclic depsipeptides are reacted with sulfonylation, sulfenylation, thiocyanisation or phosphorylation reactives, if required in the presence of catalysts, auxiliary substances and/or diluents. Also disclosed are the new compounds so obtained and their use as endoparasiticides. |
