For a recent example and key references on the Conia-ene reaction, see: In our reaction, the NHC might generate a 1,3-enophile undergoing a concerted Conia-ene-type reaction. Despite different transition-state geometries of the Conia-ene and our reaction (six- vs five-membered, respectively), the overall similarity, including the polarity of the reacting olefins, is striking.
