Enantioselective Synthesis of (S)-γ-Amino Alcohols by Ru/Rh/Ir Catalyzed Asymmetric Transfer Hydrogenation (ATH) with Tunable Chiral Tetraaza Ligands in Water
Abstract(R/S)-γ-Amino alcohols are the key intermediates for the preparation of Fluoxetine, Atomoxetine, Nisoxetine and Duloxetine. In this paper, we describe an effective method to obtain (S)-γ-amino alcohols by Ru/Rh/Ir catalyzedasymmetric transfer hydrogenation with tunable chiral tetraaza ligands (L1–L5) in HCOONa/H2O system. The asymmetric reduction of acetophenone with [Ru(p-cymene)Cl2]2/L1

Provided is a process for the preparation of enantiomerically pure 1-substituted-3-amino-alcohols, 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 the formula
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-alkyl or 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.
