Abstract: Abstract Highly sterically hindered N-heterocyclic carbenes (NHCs), can be readily prepared from the corresponding anilines, and serve as organocatalysts in NHC-catalyzed homoenolate cross-annulation of α,β-enals and aryl aldehydes. This catalysis enables the convergent construction of… read more here.
