    • note
    • It should be pointed out that only three ligands depicted in Scheme 2 were examined in the asymmetric transfer-hydrogenation of acetophenone. The structural resemblance between these and the other 2-(aminomethyl)oxazoline ligands suggest a similarly poor outcome of the reaction. In fact, in a recent report a similar oxazoline-based ligand made from L-proline was used in the same reaction and this resulted in poor yields and moderate enantioselectivity; see ref 11c.
