Enolates with Imines. -Based on a ternary complex reagent, which comprises three components, a chiral ether ligand, an achiral lithium amide and (I), the asymmetric addition of (I) to an imine (II) leads to the Ξ²-lactams such as (III) and (V) in high enantiomeric excess. The enantioselectivity and
