Synthesis of Oxygenated Heterocyclic Compounds via Gold-Catalyzed Functionalization of ,-Systems,rocycles in novel, practical, and efficient ways. In this chapter we have selected the most representative examples of the use of gold catalysis for the synthesis of oxygenated heterocycles, with an organization based on the type of reaction. Each section pretends to give an overview of the potentia

Synthesis of Oxygenated and Nitrogen-Containing Heterocycles by Gold-Catalyzed Alkyne Oxidation,heterocycles. In this chapter, gold-catalyzed oxidations of alkynes are discussed in the context of constructing synthetically versatile cyclic structures of these types. In cases of oxygenated heterocycles, external nucleophilic oxidants and in particular pyridine/quinoline N-oxides are employed. I

Synthesis of Heterocyclic Compounds via Gold-Catalysed Enyne Rearrangements,een used in a broad sense to include reactions involving cyclopropyl gold carbene intermediates formed by initial enyne cyclisation, which can undergo many different transformations to give a wide range of heterocyclic structures. Other transformations involving rearrangement of propargylic esters a

,C–H Functionalisation of Heteroaromatic Compounds via Gold Catalysis, hydroheteroarylation of multiple bonds or Friedel–Crafts-type substitution reactions with heteroaromatic nucleophiles. These reactions are redox neutral and take advantage of the Lewis acidity of Au complexes. The reactivity of [Au(I)] and [Au(III)] in C–H activation of heteroaromatics is also disc

Enantioselective Gold-Catalyzed Synthesis of Heterocyclic Compounds,these molecules via intermolecular, intramolecular, and tandem cyclization strategies. Additionally, asymmetric hydrogenation and epoxidation approaches are detailed. These methodologies generally utilize substrates containing soft, unsaturated carbon-carbon bonds, which can easily interact with the
