| titleOfInvention |
Herbicidal, optically active R(+)-dichloropyridyloxy-alpha-phenoxy-propionic acid-propargylesters, process for their preparation and their use in herbicidal compositions |
| abstract |
The present invention relates to the new optically active enantiomers of halopyridyloxy-a-phenoxy-propionic acid derivatives, having the R and / or S configuration on the asymmetric carbon atom marked with, which has the formula in which Hal is chlorine or bromine, X is hydrogen, chlorine or bromine and A is one of the groups - -COOR 1 , CO-SR 2 or mean, where R 1 to R 4 are hydrogen or optionally substituted hydrocarbon radicals, R 1 and R 2 but also cations. The invention further relates to the preparation of these optically active isomers by resolution of the underlying propionic acid with an optically active amine or by asymmetric synthesis of a halopyridyloxyphenol and an optically active lactic acid derivative with nucleofugic group Y of the formula n n n One of the two stereoisomers (R or S form) has a better herbicidal action than the other or as the known racemate and serves as a herbicidal active ingredient in herbicidal compositions for weed control. |
