摘要:
The 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.
