  • Patent number: 7164025
    Abstract: The present invention pertains to a process for obtaining a single enantiomer, d or l, of threo-methylphenidate, comprising resolution of a mixture of the enantiomers; racemisation of the unwanted enantiomer, to give a mixture of all four stereoisomers; and separation of the erythro stereoisomers, to leave the same mixture of enantiomers for resolution.

  • Patent number: 6384227
    Abstract: An optically-enrichedpiperidine-2-carboxanlidecompound, in which the piperidine is optionally N-alkylated, is racemized by heating the compound in an aqueous medium, provided that the medium includes an organic co-solvent if the compound is N-alkylated. This process is particularly valuable, in conjunction with a resolution process, for the manufacture of levobupivacaine.
