Prochiral diesters bearing an oxindole skeleton were efficiently prepared from oxindole. Cholinesterase-catalyzed hydrolysis of prochiral dipropionate afforded an optically active monoalcohol of 95% e.e. The obtained monoalcohol might find use as a versatile intermediate in the enantioselective synthesis of indole alkaloids. (C) 2001 Elsevier Science Ltd. All rights reserved.
