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.
钯催化剂(Pd(OAc)2 / PPh3)在80°C下与钯催化剂(Pd(OAc)2 / PPh3)组装在一起,从而合成了降冰片烯,1-烯基或芳基卤化物和氰化物亲核试剂这三种组分,从而获得了立体选择性的顺式-外型-2-氰基-3 -烯基-或芳基降冰片烷,可能是目前有吸引力的PGH类似物的重要中间体。
