Palladium-Catalyzed α‑Ketocyclopropanation of Norbornenes with Propargyl Acetates
Propargyl
acetates reacted with norbornene in the presence of a catalytic amount
of tetrakis(tripheylphosphine)palladium to give cyclopropyl ketones.
The reaction proceeded with high stereoselectivity, affording a single
stereoisomer. The reaction of various substituted norbornenes gave
the corresponding cyclopropanes in moderate to good yields
