Radical N-heterocyclic carbene catalysis for β-ketocarbonyl synthesis

N-Heterocyclic carbene-catalyzed radical cross-coupling between aldehydes and α-bromoesters or α-bromoamides is described. β-Ketocarbonyl compounds having a quaternary carbon center at the α-position can be synthesized under mild reaction conditions. Both aromatic and aliphatic aldehydes are suitable acyl donors by employing proper NHC catalyst precursors.

Domino Aryne Annulation via a Nucleophilic-Ene Process

1,2-Benzdiyne equivalents possess the unique property that they can react with two arynophiles through iteratively generated 1,2- and 2,3-aryne intermediates. Upon rational modification on the second leaving group of these aryne precursors, a domino aryne annulation approach was developed through a nucleophilic-ene reaction sequence. Various benzo-fused N-heterocyclic frameworks were achievable under transition metal-free conditions with a broad substrate scope.
