Formal metal-free γ-arylation of 1,3-dicarbonyl compounds: Via an isomerisation/1,4-addition/[3,3]-sigmatropic rearrangement sequence

A metal-free redox arylation of alkynes with sulfoxides has been developed to provide unconventional access to diverse γ-arylated 1,3-dicarbonyl compounds in an atom-economical manner. Mechanistic studies suggest that a conjugated allenone intermediate was generated in situ, which solves the problem of reactivity and regioselectivity of unsymmetrical dialkyl-substituted internal alkynes and enables the functionalisation of a broad range of substrates bearing electron-withdrawing functional groups. The resulting arylated 1,3-dicarbonyl compounds are versatile and useful building blocks for further functionalisation. This journal is

Cycloisomerization of Conjugated Allenones into Furans under Mild Conditions Catalyzed by Ligandless Au Nanoparticles

Au nanoparticles supported on TiO2 (1 mol %) catalyze the quantitative cycloisomerization of conjugated allenones into furans under very mild conditions. The reaction rate is accelerated by adding acetic acid (1 equiv), but the acid does not participate in the protodeauration step as in the corresponding Au(III)-catalyzed transformation. The process is purely heterogeneous, allowing thus the recycling and reuse of the catalyst effectively in several runs.

Facile conversion of trialkylsilyl esters to alkyl esters mediated by tetrabutyl-ammonium fluoride trihydrate

Trialkylsilyl esters can be smoothly converted into the corresponding alkyl esters by treatment with tributylammonium fluoride trihydrate (TBAF·3H2O) and alkyl halides in THF. This direct transformation was found applicable to the formation of lactones through intramolecular alkylations.
