Abstract

PURPOSE:To obtain the titled phenylethanol and ester useful as a synthetic raw material of pharmaceuticals, agricultural chemicals, perfumes, etc., economically on an industrial scale, by treating a specific compound with an enzyme having the activity of asymmetric hydrolysis esterase. CONSTITUTION:A 0.1-50W/V% aqueous suspension of a fatty acid ester of (R,S)-2-halo-1-phenylethanol (A) of formula I (X is halogen; R is 1-7C aliphatic hydrocarbon group) is added with 1-1/500pts. (based on 1pt. of the component A), and subjected to the asymmetric hydrolysis reaction at 10-45 deg.C and 4.0-8.0pH under stirring to produce (S)-2-halo-1-phenylethanol (B) of formula II (X is halogen) and a fatty acid ester of (R)-2-halo-1-phenyl-ethanol (C) of formula III (X and R are same as above). The component B and the component C are separated from the reaction product by the extraction with an organic solvent and the chromatographic treatment to obtain an optically active 2-halo-1- phenylethanol and its ester.

The reaction is carried out at a temperature of 35° C. with stirring. pH is 4.0-8
.. It is fine if it is within the range of 0, but as the hydrolysis reaction progresses, the pI of the reaction solution tends to be acidic, so it is recommended to maintain the pH at 6.0 to 7.5 with an appropriate alkaline aqueous solution such as Naori. If the enzyme has strict asymmetric discrimination, the hydrolysis reaction will stop when one-half of the alkali of the substrate is consumed, and it can be known that the reaction has ended.
