Stereoselective cyclotrimerization of enantiopure iodonorbornenes catalyzed by Pd nanoclusters for C(3) or C(3v) symmetric syn-tris(norborneno)benzenes.
C(3) or C(3v) symmetric enantiopure syn-tris(norborneno)benzenes with various functional groups were synthesized through Pd-catalyzed cyclotrimerization of enantiopure iodonorbornenes. The generality of Pd-catalyzed cyclotrimerization for syn-tris(norborneno)benzenes were well-demonstrated.
