Synthesis of 3-alkylcoumarins from salicylaldehydes and α,β-unsaturated aldehydes utilizing nucleophilic carbenes: A new umpoled domino reaction

Starting from salicylaldehydes and α,β-unsaturated aldehydes, a new coumarin synthesis in ionic liquids is presented. The key feature is the generation of N-heterocyclic carbenes (NHC) and an Umpolung reaction. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
