ChemInform Abstract: Asymmetric Benzoylation of meso‐Hydrobenzoin Using a Reusable Tripodal Imidazoline—Pyridine—Cu Catalyst.

Abstract

A catalyst system generated from Cu(BF4)2 and new chiral imidazoline—pyridine ligands is used to promote the title reactions of meso‐diols (III) to afford the corresponding adducts with enantioselectivities up to 85%.
