Palladium‐Catalyzed Decarboxylative Asymmetric Allylic Alkylation of β‐ketoesters: An Unusual Counterion Effect

Abstract

Buy one, get one free: Both enantiomers of tetralone and indanone derivatives are available in a one-pot procedure from 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.
