Enantioselective Oxidative Multi-Functionalization of Terminal Alkynes with Nitrones and Alcohols for Expeditious Assembly of Chiral α-Alkoxy-β-amino-ketones.
TL;DR: In this article, the first asymmetric three-component reaction of commercially available terminal alkynes with nitrones and alcohols was reported, which affords α-alkoxy-β-amino-ketones in good yields with high to excellent enantioselectivity using combined catalysis by an achiral gold complex and a chiral spiro phosphoric acid (CPA).

Gold-Catalyzed Intermolecular Alkyne Hydrofunctionalizations—Mechanistic Insights
TL;DR: An overview of the current state of mechanistic understanding of gold-catalyzed intermolecular alkyne hydrofunctionalization reactions is presented in this paper, where the effects of the nature of the employed alkynes substrate and of the gold catalyst (employed ligands, counteranions, gold oxidation state), of additional additives and of reaction conditions are also considered.

Photocatalytic functionalizations of alkynes
TL;DR: In this article, the authors present a survey of visible light mediated functionalization reactions of alkynes, wherein they have been transformed into α-oxo compounds, β-keto sulfoxides, substituted olefins, N-heterocycles, internal alkynes and sulfur containing compounds.

Copper(I)-Catalyzed Enyne Oxidation/Cyclopropanation: Divergent and Enantioselective Synthesis of Cyclopropanes.
TL;DR: In this article, an efficient copper(I)-catalyzed enyne oxidation/cyclopropanation for the modular synthesis of cyclopropane derivatives is described, which represents the first non-noble metal-catalystzed enynes oxidation and compropanization by the in situ generated α-oxo copper carbenes.

Ligand effects in homogeneous Au catalysis.
TL;DR: The ways in which selectivity can be controlled in homogeneous Au catalysis are enumerated, in the hope that lessons to guide catalyst selection and the design of new catalysts may be distilled from a thorough evaluation of ligand, counterion, and oxidation state effects as they influence chemo-, regio-, and stereoselectivity in homogeneity AuCatalysis.

Gold-catalyzed cycloisomerizations of enynes: a mechanistic perspective.
TL;DR: The proposed involvement of cyclopropyl metal carbenes of type 4 in the electrophilic activation of enynes by transition metals was first substantiated in reactions catalyzed by Pd(II), in which the initially formed cycloprostyl palladiumCarbenes undergo [4 + 2] cycloaddition with the double bond of the conjugate enyne.
