allyl chloroformate and their β‐ketoesters by using the same catalyst system (see scheme; dba=dibenzylideneacetone, 1,2‐DCE=1,2‐dichloroethane, THF=tetrahydrofuran). The details of this remarkable effect were investigated by performing scavenging experiments and a variety of substrates were successfully used in the procedure.
