chiral amines 7–13 mediated the asymmetric condensation reaction of lithium ester enolate 2 with benzaldehyde p-anisidine imine 3 giving the corresponding β-lactam 4 in up to 75% ee. It became apparent that coexistence of 2 and chiral lithium amides derived from 7–13 is an important factor for the enhancement of the reactivity and enantioselectivity of 2.
