| 摘要 |
The invention relates to novel substituted optically active aminotriazines having at least two asymmetrically substituted carbon atoms of the formula (I),in whichA represents a single bond or represents in each case straight-chain or branched alkanediyl or oxaalkanediyl having in each case up to 6 carbon atoms,Z represents certain carbocyclic or heterocyclic radicals and the substituents R1, R2, R3, R4 and Y are as defined in the description, with the proviso that in each individual case R2, R3 and Y are different from one another and that the substituents at the two carbon atoms to which R2 and R3 or R4 are attached are configured as follows:(a) R configuration at the carbon atom to which R2 and R3 are attached and R configuration at the carbon atom to which R4 is attached ("R,R-diastereomers"),(b) R configuration at the carbon atom to which R2 and R3 are attached and S configuration at the carbon atom to which R4 is attached ("R,S-diastereomers"),(c) S configuration at the carbon atom to which R2 and R3 are attached and R configuration at the carbon atom to which R4 is attached ("S,R-diastereomers"),(d) S configuration at the carbon atom to which R2 and R3 are attached and S configuration at the carbon atom to which R4 is attached ("S,S-diastereomers"),(e) R configuration at the carbon atom to which R2 and R3 are attached and racemic configuration at the carbon atom to which R4 is attached ("R,racdiastereomers"),(f) S configuration at the carbon atom to which R2 and R3 are attached and racemic configuration at the carbon atom to which R4 is attached ("S,rac-diastereomers"), and to a process for preparing the compounds of the formula (I) and to their use as herbicides.
