CA 2229312

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.

L'invention concerne un procédé de dissociation d'amides optiquement actifs pour former des acides carboxyliques et des amines optiquement actifs tout en maintenant le centre de chiralité. Selon l'invention, on réalise une hydrolyse des amides en présence d'un polyol ou d'un amino-alcool et d'un hydroxyde alcalin ou alcalino-terreux.
