Expanding the horizon of intermolecular trapping of in situ generated α-oxo gold carbenes: Efficient oxidative union of allylic sulfides and terminal alkynes via C-C bond formation

With a new P,S-bidentate phosphine as the ligand to gold(i), the α-oxo gold carbenes generated in situ via gold-catalyzed intermolecular oxidation of terminal alkynes were effectively trapped by various allylic sulfides, resulting in the formation of α-aryl(alkyl)thio-γ,δ- unsaturated ketones upon facile [2,3]sigmatropic rearrangements.

Reactions of α-or χ-Phenylthio Substituted Extended Enolate Anions Derived from Esters

The title anions are alkylated and acylated (α series only) exclusively at the α position.The α-phenylthio products give χ-phenylthio compounds by the PhS shift and the PhS group may be removed from the products in a number of ways.

EXTENDED ENOLATE IONS FROM γ-PHENYLTHIO-CROTONATE ESTERS

Substituted γ-phenylthio-crotonate esters (7) can be made by and PhS shifts: they form extended enolate anions which react with electrophiles at the carbon atom α to the carbonyl group and γ to sulphur.
