| titleOfInvention | Herbicidal, optically active r(+)-dichloropyridyloxy-alpha-phenoxy-propionic acid-propargylesters, process for their preparation and their use in herbicidal compositions |
| abstract | 1. Claims for the Designated States : BE, CH, DE, FR, GB, IT, NL Novel optically active R(+)isomeric propargyl esters of alpha-4-[3',5'-dichloropyridyl-(2')-oxy)phenoxy]propionic and thiopropionic acid of the formula I see diagramm : EP0006608,P7,F4 R(+)-Form wherein X is oxygen or sulfur. 1. Claims for the Contracting State : AT A process for the production of novel optically active R(+)-isomeric propargyl esters of alpha-4-[3',5'-dichloropyridyl-(2')-oxy)phenoxy]propionic and thiopropionic acid of the formula I see diagramm : EP0006608,P8,F4 R(+)-Form wherein X is oxygen or sulfur, which process comprises reacting the dichloropyridyloxy phenol of the formula II see diagramm : EP0006608,P8,F5 in the presence of a base, with an optically active lactic acid derivative of the formula III see diagramm : EP0006608,P9,F1 which has the S-configuration at the *C atom and wherein A' is one of the groups -COOR1 or -CN and R1 is hydrogen or a lower alkyl radical, and Y is a leaving group which leaves the molecule in the form of a compound HY and is replaced by the deprotonated radical of the phenol of the formula II at the optically inverse position of the *C atom, and converting the resultant optically active derivative into the free R(+)-propionic acid or R(+)-thiopropionic acid, and then preparing the propargyl ester from said acid. |
