Enantioselective trans-acylation of the racemic benzimidazolyl ethanols was achieved via enzymatic kinetic resolution. A range of commercially available lipases were screened and Novozyme-435 was established as the optimal catalyst. N-Protection was found to be mandatory for effective transesterification. However, electron-withdrawing substituents reduced the enantioselectivity to some extent when compared to the other substituents. (C) 2008 Published by Elsevier Ltd.
