Title (DE) TRENNUNG EINES ENANTIOMERENGEMISCHS VON (R)- UND (S)-3-AMINO-1-BUTANOL
(EN) SEPARATION OF AN ENANTIOMER MIXTURE OF (R)- AND (S)-3-AMINO-1-BUTANOL
(FR) SÉPARATION D'UN MÉLANGE D'ÉNANTIOMÈRES DE (R)- ET DE (S)-3-AMINO-1-BUTANOL
Abstract:
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Trennung eines Enantiomerengemischs von gegebenenfalls am Sauerstoffatom geschütztem (R)- und (S)-3-Amino-1-butanol sowie ein Verfahren zur Herstellung von im Wesentlichen enantiomerenreinem (R)-3-Amino-1-butanol, das gegebenenfalls am Sauerstoffatom eine Schutzgruppe trägt.
(EN) The present invention relates to a method for separating an enantiomer mixture of (R)- and (S)-3-amino-1-butanol possibly protected at the oxygen atom and to a method for producing substantially enantiomer-pure (R)-3-amino-1-butanol that possibly carries a protective group at the oxygen atom.
(FR) La présente invention concerne un procédé permettant de séparer un mélange d'énantiomères de (R)- et de (S)-3-amino-1-butanol à atome d'hydrogène protégé et un procédé de production de (R)-3-amino-1-butanol sensiblement énantiopur dont l'atome d'hydrogène porte éventuellement un groupe protecteur.
