Abstract
Evaluation of some of the possible lipase-catalyzed transformations ha s been done in order to prepare both enantiomers of betaxolol. Resolut ion of betaxolol by lipase-catalyzed hydrolysis of its bis-acetylated derivatives 4 led to (-)- and (+)-enantiomers with an ee of 20 and 60% , respectively. When the resolution was performed on the chlorohydrin precursor 6 of betaxolol, (-)- and (+)-enantiomers were obtained with an ee of 91 and 75%, respectively.
