  • Patent number: 5679799
    Abstract: There is disclosed a method for producing oxyindoles, which comprises reacting a 2-halogenophenylacetic acid or its salt with ammonia in the presence of a copper salt catalyst, and heating a mixture of the produced 2-aminophenylacetic acid or its salt and oxyindoles in the presence of an acid catalyst, to subject the 2-aminophenylacetic acid or its salt to a ring-closure reaction. According to this method, relatively readily available 2-halogenophenylacetic acids are used as a starting raw material to industrially produce highly pure oxyindoles in high yield in one pot without involving complicated steps. Further, since the amination is carried out at a temperature greatly lower than that of the conventional art, the lowering of the pH of the reaction liquid can be suppressed. Therefore, the restrictions on the specifications of the reaction apparatus, such as corrosion prevention and pressure resistance, can be mitigated.

  • Patent number: 5468873
    Abstract: The present invention provides a process for preparing 2-oxindole-1-carboxamides, comprising reacting N-acyl 2-oxindole-1-carboxamides with alcohols in the presence of aprotic weak Lewis acid catalysts. In certain processes of the present invention a 2-oxindole-1-carboxamide is prepared from a 2-oxindole by reacting the 2-oxindole with an acyl isocyanate to produce the N-acyl 2-oxindole-1-carboxamide as an intermediate, which is then reacted with alcohol in the presence of aprotic weak Lewis acid catalysts The N-acyl 2-oxindole-1-carboxamide intermediate may be converted to the 2-oxindole-1-carboxamide without isolation.

  • Patent number: 5387695
    Abstract: A process for chemically resolving a mixture of enantiomers of primary amines, such as enantiomers of 1,3-dimethyl-5-methoxyoxindolylethylamine, provides one of the enantiomers in the form of a tartaric acid salt. In carrying out the process, an enantiomeric mixture is contacted with a chiral acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The resulting precipitate can then be recovered. The chiral acid is selected from the group consisting of dibenzoyl-D-tartaric acid, dibenzoyl-L-tartaric acid, ditoluoyl-D-tartaric acid, and ditoluoyl-L-tartaric acid. The precipitates can be used in the synthesis of stereospecific forms of physostigmine.
