The (-)-sparteine-mediated enantioselective addition of organolithium compounds to achiral ferrocenylimines and diastereoselective addition of organolithium reagents to chiral ferrocenyl imines de-rived from inexpensive (R)- and (S)-1-phenylethylamines were carried out. The influence of the imine struc-ture, as well as the effect of experimental conditions on the reaction was studied. Modest enantiomeric ex-cess was obtained with the achiral imines. And high diastereoselectivity was achieved with the chiral imine derived from (R)-(+)-1-phenylethylamine in the presence of the Lewis acid BF3•OEt2.

Key words: ferrocenylimine, (-)-sparteine, asymmetric addition, Lewis acid
