(Chemical Equation Presented) A new chiral benzimidazolide is developed as a nonenzymatic acylating agent for enantioselective benzoylation of racemic α-amino esters. The process is highly efficient, which exhibits uniformly high enantioselectivity for α-amino esters with or without aryl substituents under mild reaction conditions. The chiral benzimidazolide is inexpensive and is easily accessible.

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.
