Abstract: An efficient and flexible asymmetric synthesis of chiral ferrocenylamines 3a-c via diastereoselective addition of organolithium compounds to chiral imines is described. High diastereoselectivity(93% de) was observed with ferrocenecarboxaldehyde imine 2b in the presence of the Lewis acids BF3oOEt2.
