Benzimidazolium-based N-heterocyclic carbene (NHC)-boryl radical catalyzes cascade cyclization reactions to construct polycyclic compounds both intra- and intermolecularly. This catalytic cascade radical reaction allows rapid construction of complex molecular architectures through the formation of two or three bonds in a single operation, respectively.

We report a gold-catalyzed [2+2+2]-cycloaddition of 1,7-enynes with carbonyl species; our experimental data suggest that the resulting oxacyclic cycloadducts arose from an interception of gold-containing cyclobutenium intermediates with carbonyl species.
