  • Publication number: 20110207946
    Abstract: Provided is a process for the preparation of enantiomerically pure 1-substituted-3-aminoalcohols, particularly of (S)-(?)- and (R)-(+)-3-N-methylamino-1-(2-thienyl)-1-propanol, by asymmetrically hydrogenating salts of a carboxylic acids with an aminoketone of formula (II), wherein R1 is selected from the group consisting of 2-thienyl, 2-furanyl and phenyl, each optionally substituted with one or more halogen atoms and/or one or more C1-4-alkoxy groups, and wherein R2 is C1-4-alkyl or phenyl, each optionally substituted with one or more halogen atoms and/or one or more C1-4-alkyl or C1-4-alkoxy groups, and wherein the corresponding aminoalcohols are obtained by subsequent hydrolysis of their salts. Furthermore provided are salts of a carboxylic acid with said aminoketones and the aminoalcohols obtained by asymmetriacally hydrogenating said aminoketones, respectively.

  • Publication number: 20110152543
    Abstract: The present invention describes a novel process for the preparation of optically active (S)-(?)-2-(N-propylamino)-5-methoxytetraline and (S)-(?)-2-(N-propylamino)-5-hydroxytetraline compounds based on the optical resolution of mixtures of the enantiomers of 2-(N-propylamino)-5-methoxytetraline and 2-(N-propylamino)-5-hydroxytetraline respectively. This process comprises (a) reacting a mixture of the enantiomers of said compounds with an optically active organic acid to form diastereoisomeric salts and separating the salts by crystallization. Said compounds are useful in the preparation of (6S)-(?)-5,6,7,8-tetrahydro-6-[propyl-(2-thienyl)ethyl]amino-1-naphthol (Rotigotine). Rotigotine is a dopamine agonist and is indicated for the treatment of Parkinson's disease.
