Gold(I)-Catalyzed Oxidative Amination of β-Amino-ynones to Quaternary Ammonium-olate Salts: The Benefit of a P,N-Bidentate Ligand

A novel P,N-bidentate ligand-assisted gold-catalyzed oxidative amination of β-amino-ynones has been developed, allowing the simple and efficient construction of various quaternary ammonium-olate salts in good to excellent yields. These unprecedented quaternary ammonium-olate salts can be isolated and purified via simple suction filtration. The broad substrate scope, easy purification, easy further transformation, and mild conditions make it a viable alternative for the synthesis of various quaternary ammonium-olate salts.

Gold or no gold: One-pot synthesis of tetrahydrobenz[b]azepin-4-ones from tertiary n-(but-3-ynyl)anilines

Depending on the tertiary aniline substrates, an efficient, one-pot synthesis of tetrahydrobenz[b]azepin-4-ones needs either gold catalysts or no catalyst at all. In the reaction, the aniline nitrogen plays a unique role in relaying "O" from m-CPBA to a tethered C-C triple bond, which is inert to the oxidant under the mild reaction conditions.

Water-Tolerant Unstabilized Carbanion Equivalents: Bismuth(III) Chloride-Aluminum Promoted Alkylations of Immonium Cations to Amines in Aqueous Media

In the presence of bismuth(III) chloride-metallic aluminum, alkyl as well as allyl halides react with N-(alkylamino)benzotriazoles at 20 deg C in THF-water to give the corresponding homoalkylated amines in high yields.
