Definitions
- the present invention relates to piperazine compounds of the general formula I defined below and their use as herbicides.
- the invention also relates to crop protection agents and to a method of controlling undesired plant growth.
- the thaxtomines A and B produced by the plant pathogen S. scabies are natural substances with a central piperazine-2, 5-dione ring which carries a 4-nitro-indol-3-ylmethyl radical in the 3-position and a benzyl radical optionally substituted by OH in the 2-position. Because of their plant-damaging effect, the possibility of using this class of compounds as herbicides was also investigated (King R.R. et al., J. Agric. Food Chem. (2001) 49, 2298-2301).
- EP-A 181 152 and EP-A 243122 describe structurally similar piperazine compounds and their use as antagonists of the platelet activating factor.
- WO 99/48889, WO 01/53290 and WO 2005/011699 describe 2,5-diketopiperazine compounds which have, in the 3- or 6-position, a 4-imidazolyl radical bonded via a methylene or methine group and in the another 3- or 6-position benzyl or Benzylidenrest have. These compounds are antitumor agents.
- R is H or methyl, as an anti-inflammatory drug in medicine.
- R y is hydrogen or benzyl and R x is hydrogen, acetyl or Isopro- pyloxycarbonyl, as precursors for the preparation of Ecteinascidinen.
- An object of the present invention is to provide compounds having herbicidal activity.
- compounds are to be made available which have a high herbicidal action, in particular even at low application rates, and their compatibility with crop plants for commercial exploitation is sufficient.
- the present invention thus provides piperazine compounds of the general formula I.
