  • Patent number: 6846955
    Abstract: The invention relates to a process for racemising an enantiomer-enriched Schiff base of a primary amino acid amide with a strong base that is chemically reactive towards water. The reaction is conducted in an organic solvent. Preferably a metal alkoxide, a metal alkyl, a metal amide, or a metal hydride, in particular a metal alkoxide is applied as the strong base. As the Schiff base preferably N-benzylidene primary amino acid amide is used, with the primary amino acid amide preferably being derived from an aliphatic primary amino acid amide, for example tertiary-leucine amide. As organic solvent use is preferably made of an aromatic hydrocarbon, a cyclic, aliphatic hydrocarbon or a ether, in particular an aromatic hydrocarbon is applied. The invention may also be applied for the racemisation of an enantiomer-enriched primary amino acid amide.

  • Patent number: 6586634
    Abstract: Process for the preparation of (1S,2R)-1-amino-2-indanol-(R,R)-tartrate methanol solvate, in which in a solvent a mixture of enantiomers of cis-1-amino-2-indanol reacts at an elevated temperature with (R,R)-tartaric acid and methanol and in which optically enriched (1S,2R)-1-amino-2-indanol-(R,R)-tartrate methanol solvate crystallizes out, after which the crystals are recovered, the recovery taking place at a temperature between 10 and 50° C. in the presence of 0-20 wt. % water relative to the amount of methanol plus solvent, on the understanding that if the reaction mixture is essentially free from water the recovery substantially takes place at a temperature between 30 and 50° C. Preferably the reactants are at least in part contacted with each other at an elevated temperature and only methanol is used as solvent. Preferably the amount of (1S,2R)-1-amino-2-indanol applied is between 0.02 and 0.1 g per ml of solvent.
