Abstract: A process for producing optically active primary and secondary amines from the corresponding racemates is characterized in that (a) a racemic amine is enantioselectively acylated in the presence of a hydrolase with an ester whose acid component bears a fluorine, nitrogen, oxygen or sulphur atom at the proximity of the carbonyl carbon atom; (b) the mixture of optically active amine and optically active acylated amine is separated so that an enantiomer of amine is produced; (c) if desired the other enantiomer of the amine is extracted from the acylated amine by amide cleavage.

Abstract: The invention concerns a method of separating optically active amides to form carboxylic acids and optically active amines such thatsthe centre of chirality is maintained. The method is characterized in that the amides are hydrolyzed in the presence of a polyol or an aminoalcohol and an alkali or alkaline earth hydroxide.

Abstract: The invention relates to a method for hydrolyzing optically active amides to carboxylic acids and optically active amines with retention of the center of chirality. The hydrolysis of the amides is carried out with an alkali or alkaline earth hydroxide in the presence of 5 - 30 wt.- %, based on the amid e used, of a polyol or an amine alcohol.
