Gold-catalyzed intermolecular hydroamination of allenes with sulfonamides

Beilstein Journal of Organic Chemistry, 2013
A co-catalyst of (PPh3)AuCl/AgOTf for the intermolecular hydroamination of allenes with sulfonamides is shown. The reaction proceeded smoothly under mild conditions for differently substituted allenes giving N-allylic sulfonamides in good yields with ...

When Phosphosugars Meet Gold: Synthesis and Catalytic Activities of Phostones and Polyhydroxylated Phosphonite Au(I) Complexes

Molecules, 2015
The synthesis and characterization of P-chiral phosphonite-, phosphonate- and thiophosphonate-Au(I) complexes are reported. These novel ligands for Au(I) are based on glycomimetic phosphorus scaffolds, obtained from the chiral pool.

Gold Catalysis and Fluorine

Israel Journal of Chemistry, 2010
AbstractPerforming gold‐catalyzed organic transformations in the presence of fluorinating reagents can lead to both fluorinated and non‐fluorinated products. Gold(I) complexes can activate alkynes towards nucleophilic attack by fluoride leading to fluoroalkenes under mild conditions.

New Frontiers in Gold Catalyzed Reactions

, 2012
For many years, gold has been regarded as a poor catalyst due to its chemical inertness towards reactive molecules such as oxygen and hydrogen. The interest in using gold in catalysis has increased during the last 20 years, since Haruta reported the ...

Gold-catalyzed post-Ugi alkyne hydroarylation for the synthesis of 2-quinolones

Beilstein Journal of Organic Chemistry, 2018
A series of propargylamides containing an electron-rich benzene ring was prepared through the Ugi reaction of 3,5-dimethoxyaniline with various propiolic acids, aldehydes and isocyanides. Subjecting these adducts to a gold-catalyzed intramolecular alkyne
