✦ Synopsis

A mechanistic investigation into the addition of diethylzinc to aromatic aldehydes catalyzed by chiral ohydroxyaryldiazaphosphonamides is described. A positive non-linear effect has been encountered and the X-ray structure of catalyst anti-1 has been realized.

A series of chiral ligands 2a-d were conveniently prepared from b-amino alcohols through a two-step sequence and applied to catalysis of enantioselective addition of diethylzinc to benzaldehyde. Among them ligand 2c was found to show the best asymmetric induction for the reaction and catalyze the ad
