Three components, i.e., norbornene, 1-alkenyl or aryl halide, and cyanide nucleophile, were assembled with palladium catalyst (Pd(OAc)2/PPh3) in DMF at 80 °C to obtain stereoselectively cis-exo-2-cyano-3-alkenyl-or arylnorbornanes, which may be prominent intermediates for the currently attractive PGH analogues.
