PCT No. PCT/EP95/03926 Sec. 371 Date Apr. 10, 1997 Sec. 102(e) Date Apr. 10, 1997 PCT Filed Oct. 5, 1995 PCT Pub. No. WO96/11945 PCT Pub. Date Apr. 25, 1996The present invention relates to a process for the aromatic sulfonylation, sulfenylation, thiocyanation and phosphorylation of cyclic depsipeptides having 6 to 24 ring atoms which are synthesized from alpha -hydroxycarboxylic acids and alpha -amino acids and contain at least one phenyl radical, characterized in that these cyclic depsipeptides are reacted with sulfonylating, sulfenylating, thiocyanating or phosphorylating agents, optionally in the presence of catalysts, auxiliaries and/or diluents, to novel thus-obtained compounds, and to their use as endoparasiticides.
