Abstract (en)

[origin: WO2006024402A1] The invention relates to novel salts of chiral 3-halophthalic acid derivatives of formula (I) from 3-halophthalic acid anhydrides of formula (II), amines of formula (III), a method for the production thereof, the use thereof for producing chiral phthalic acid diamides of formula (V), and a novel method for producing chiral phthalic acid diamides of formula (V). According to the invention, salts of chiral 3-halophthalic acid derivatives of formula (I) are transformed into the corresponding isophthalamides of formula (VI), which are reacted with arylamine of formula (VII).
