Enantiopure 1-hydroxymethyl-2-dimethylaminomethylferrocene as efficient catalyst in the enantioselective addition of diethylzinc to aldehydes

A ferrocenyl amino alcohol possessing only planar chirality has been employed as a catalyst in the enantioselective alkylation of aldehydes with Et2Zn. Seven chiral secondary alcohols in 64?83% e.e. have been prepared.
