Kineticresolutions of (±)-3-chloro-3-arylpropanols by lipase mediated acetylation are described for the first time. Acetylation with CCL provided the best enantioselectivity amongst the enzymes used. Enantiomerically enriched products were obtained with up to 78% ee after two successive lipase-catalyzed acetylations. Different substituents on the aromatic ring and bromide, instead of chloride, on
The present invention relates to β-amino acid esters of Formula (2), and to a method for the preparation of β-amino acid esters of formula (2) by reduction of the corresponding enamines or amination of a β-keto ester followed by condensation with a halogen-substituted benzene derivative.
