  • Patent number: 6465223
    Abstract: The present invention relates to a process for resolving racemates of alkoxy-substituted primary amines by reacting with an ester in the presence of a lipase and subsequently separating the optically active amide which is formed from the unreacted optically active amine. This is followed where appropriate by hydrolysis of the optically active amide, separation of the optically active amine produced thereby from the acid from which the ester is derived, racemization and recycling of the unwanted enantiomer of the amine, and esterification and recycling of the acid.

  • Patent number: 6214608
    Abstract: A process for preparing optically active primary and secondary heteroatom-substituted amines from the corresponding racemates, which comprises a) enantioselective acylation of a racemic heteroatom-substituted amine with an ester whose acid component carries a fluorine, nitrogen, phosphorus, oxygen or sulfur atom in the vicinity of the carbonyl carbon, in the presence of a hydrolase, b) separation of the mixture of optically active heteroatom-substituted amine and optically active acylated heteroatom-substituted amine to obtain one enantiomer of the heteroatom-substituted amine, c) if required isolation of the other enantiomer of the heteroatom-substituted amine from the acylated heteroatom-substituted amine by amide cleavage.
