title: An efficient carbene-catalyzed access to 3,4-dihydrocoumarins.
abstract: Dihydrocoumarins play an important role as flavor and fragrance compounds and can be prepared efficiently from o-hydroxycinnamaldehydes in a mild, atom-economic N-heterocyclic carbene-catalyzed redox lactonization. Corresponding coumarins are accessible via a one-pot domino oxidation lactonization procedure in the presence of oxidants.
