  • Patent number: 4585887
    Abstract: Process for the production of an optically active 3-aminocarboxylic acid ester from a .beta.-keto acid ester. The .beta.-keto acid ester is converted with a chiral amine into the corresponding enamine. The enamine is converted by hydrogenation in the presence of a platinum catalyst into the corresponding N-substituted amino acid esters. Such ester mix is converted by means of HCl gas into the hydrochlorides. The latter are neutralized. Then by liberation and isolation from the neutralized products by hydrogenolysis in the presence of a palladium catalyst, the desired optically-active 3-aminocarboxylic acid ester is obtained.

  • Patent number: 4415743
    Abstract: Novel oxime ethers and oxime esters of the formula I given herein have various advantageous effects with regard to stimulation of plant growth, particularly in the early stage of development of the plant. Furthermore, such compounds have the property of rendering, in the sense of an antidote action, agricultural chemicals which would otherwise damage the plants (phytotoxic chemicals) more compatible with the cultivated plants. Herbicides that are insufficiently selective can be used for example in the presence of such oxime derivatives in specific cultivated crops for combating weeds, without disadvantageous consequences for the cultivated plants.
