✦ Synopsis


The application of a new type of polymer anchored chiral amino-oxazolinyl ligand as catalyst for the enantioselective addition of diethylzinc to aldehydes is reported. The catalyst is effective at a low ligand concentration and can be reused with minimal loss of activity.

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
