Definitions
- the invention relates to new deoxycyclodepsipeptides, processes for their preparation and their use for controlling parasites, in particular helminths in the
- cyclodepsipeptides with antiparasitic activity have been described in the literature.
- a cyclooctadepsipeptide with the designation PF 1022 is known from EP-A 382 173.
- 24-membered cyclodepsipeptides are known from EP-A 626 376, EP-A 634 408 and EP-A 718 293. Their anthelmintic effect is not satisfactory in all cases.
- the invention relates to new deoxycyclodepsipeptides which, through complete or partial chemoselective reduction of the carbonyl groups, increase the amide function
- the cyclodepsipeptides serving as starting products are alternately composed of 4 ⁇ -
- ⁇ -Aminocarboxylic acids are natural or synthetic amino acids that can be the same or different. They can be N-alkylated, ie substituted by a straight-chain or branched CC 4 alkyl group, preferably a methyl group, which in turn can be substituted.
- ⁇ -Hydroxycarboxylic acids are natural and synthetic 2-hydroxycarboxylic acids that can be the same or different.
- the reduction takes place either directly or in a multi-stage process depending on the reducing agent chosen.
- Complete or partial reduction means that e.g. in the case of an octadepsipeptide with a number of 4 amidic carbonyl groups, all 4 carbonyl groups concerned or 1 to 3 of these carbonyl groups are reduced.
- the reduction generally gives mixtures of the deoxydepsipeptides with different degrees of reduction.
- the individual components are available in different proportions, depending on the stoichiometry and type of reduction process.
- Uniform deoxydepsipeptides are obtained from the mixtures by using the usual physical or chemical separation processes.
- the products obtained in the reduction reaction can be converted chemically to further derivatives.
