The zinc-cuprous chloride promoted Reformatsky-imine addition reaction of 4-bromo-4,4-difluoroacetoacetate with aldimines derived from aromatic aldehydes and with ketimines derived from aryl alkyl ketone provided an efficient and practical access to δ-amino-γ,γ-difluoro-β-ketoesters. The scope and limitation of this procedure are also discussed.
