Abstract Chiral oxazoline ligands containing an aromatic ring were prepared from norephedrine and pyrrole-2-carbonitrile or 2-hydroxybenzoyl chloride. The synthesized ligands were used in the copper-catalyzed asymmetric addition of diethylzinc to aromatic aldehydes to provide optically active 1-arylpropan-1-ols with high conversion (92%) and enantioselectivity (up to 99% ee).
