✦ Synopsis

Optically active ferrocenyl amino alcohols have been prepared from commercially available L-alaninol, L-leucinol and L-valinol. They have been utilized as chiral ligands in the catalytic addition of diethylzinc to aldehydes. The influence of the substituents on the stereogenic centers of the ligand has been studied. Enantioselectivities up to 95% have been obtained.

Optically active ferrocenyl amino alcohols have been prepared from commercially available l-alaninol and l-leucinol. They have been used in catalytic amounts as chiral ligands in the addition of diethylzinc to benzaldehyde. 1-Phenylpropanol has thus been obtained in up to 95% enantiomeric excess.
