    Abstract: A biocatalytic method of preparing optically pure precursors of paroxetine and a method of preparing paroxetine therefrom are disclosed. A racemic trans ester precursor compound of paroxetine is first prepared. The racemic trans ester precursor compound comprises a mixture of (3S, 4R) and (3R, 4S) enantiomers. The (3R, 4S) enantiomer is hydrolyzed biocatalytically to the corresponding (3R, 4S)-trans carboxylic acid or alternatively, the (3S, 4R) enantiomer is biocatalytically hydrolyzed to the (3S, 4R)-trans carboxylic acid in a reaction catalyzed by an isolated enzyme or a microorganism. In the first instance, the unhydrolyzed (3S, 4R) enantiomer is separated from the (3R, 4S)-trans carboxylic acid, whereas in the second instance the (3S, 4R)-trans carboxylic acid is separated from the unhydrolyzed (3R, 4S) enantiomer. The (3S, 4R) enantiomer obtained following the selective hydrolysis is reduced to form a (-)-trans-(3S, 4R) primary alcohol precursor of paroxetine. Paroxetine is then formed from the (-)-trans-(3S, 4R) primary alcohol precursor.
