We herein report an N-Heterocyclic Carbene (NHC)-catalyzed annulation of ylides with ynals that provides an efficient protocol to make 4,6-disubstituted α-pyrones. This method affords a variety of α-pyrones in good to high yields as well as broad substrat

An efficient synthesis of 4,6-disubstituted α-pyrones employing redox activation of enals using N-heterocyclic carbene catalysis is reported. The strategy uses aroyl-substituted nitromethanes and enals as substrates and reactions proceed through an additi
