Synergistic Gold‐Silicon Catalysis: Unravelling Alkynyl Gold Reactivity and Application to the High‐Performance C‐Alkynylation of Glycals

Chemistry – A European Journal, EarlyView.
This research highlights an efficient and highly α‐stereoselective Au‐Si‐catalyzed alkyne transfer reaction from 1‐trimethylsilylalkynes to glycals, utilizing the bench‐stable (F5Ph)3PAuNTf2 complex at low catalyst loadings (0.2–1 mol%). DFT mechanistic investigations revealed the nucleophilic character of the in situ formed electron‐deficient ...

Analytical Study of Lanolin as Potential Biomarker of Prehistoric Sheep‐Shearing Practice

Chemistry–Methods, EarlyView.
Lanolin, a complex wax found on sheep wool, accumulates on shearing tools, such as flint and obsidian blades, used since the Neolithic. This study explores lanolin's degradation patterns as a potential biomarker for prehistoric sheep‐shearing practices, employing micro‐Fourier transformed infrared spectroscopy, hyperspectral imaging, and gas ...

Sequential Ester Homologation–Nucleophile‐Guided Functionalization: A Chemoselective Access to Thioesters, Amides, and Acids

Chemistry–Methods, EarlyView.
The homologation of esters—in the presence of a lithium carbenoid—to thioesters, amides, and carboxylic acid is reported. By controlling the tetrahedral intermediate collapsing and promoting a series of rearrangements ultimately leading to a high electrophilic ketene, the subsequent incorporation of S‐, N‐, and O‐nucleophilic elements furnishes the ...
