Process for the preparation of certain enantiomeric pairs of the alpha-cyano-3-phenoxy-4-fluoro-benzylester of permethrinic acid |
| abstract |
The present invention relates to a process for the preparation of the enantiomeric pairs (1R-3R-αS + 1S-3S-aR) and (1R-3S-aS + 1S-3R-aR) from the mixture of all eight stereoisomers of the compound αR / S-cyano -3-phenoxy-4-fluorobenzyl-3R / S- (2,2-dichlorovinyl) -2,2-dimethyl-1 R / S-cyclopropanecarboxylic acid ester, which is characterized in that this mixture in a secondary or tertiary alkylamine dissolves 2 - ε C atoms per alkyl part and the enantiomeric pairs (1R-3R-αS + 1S-3S-αR) and (1R-3S-αS + 1S-3R-aR) crystallize from the solution. |
