Hydrolases from the liver acetone powders (LAPs) of bovine, cat, chicken, turkey, lamb, pig, rabbit, and rat were assessed for the enantioselective hydrolysis of acetates of 1-(4-chlorophenyl)ethanot, 1-(3-bromophenyl)ethanol, 1-(4-chlorophenyl)propanol, 1-(4-bromophenyl)propanol, and 1-(3-bromophenyl)propanol. The enantioselectivity of the hydrolytic reaction was dependent upon the liver hydrolase, substrate, pH of the reaction media, and the cosolvent. The most ester selective LAP was from chicken, and the resulting alcohols had the highest ee (80% to >99%). All of the LAPs tested catalyzed the hydrolysis of 1-(4-chlorophenyl)ethanol, except for lamb LAP. (C) 2008 Elsevier Ltd. All rights reserved.
