Abstract

Abstract: Chiral oxazoline ligands containing an aromatic ring were prepared fromnorephedrine and pyrrole-2-carbonitrile or 2-hydroxybenzoyl chloride. Thesynthesized ligands were used in the copper-catalyzed asymmetric addition ofdiethylzinc to aromatic aldehydes to provide optically active 1-arylpropan-1-olswith high conversion (92%) and enantioselectivity (up to 99% ee).
