The enantiopure multi-functional anti Alzheimer's drug, Ladostigil (TV3326), was prepared by using asymmetric transfer hydrogenation (ATH) as a key step catalyzed by Ru-Cs-DPEN in an HCOONa-H2O-surfactant system. Good chemical yields with high enantiomeric excess were obtained and the catalyst could be recycled another five times. (C) 2012 Elsevier Ltd. All rights reserved.
