Abstract (en)
[origin: DE19827163A1] The invention relates to a method for asymmetrically disubstituting carboxylic acid amides on the geminal carbonyl-C-atom using two different grignard reagents in the presence of a metal alcoholate compound used as a catalyst and in the presence of another organometallic compound used as a co-catalyst.
