P‐Directed and Lewis Acid‐Assisted Pd‐Catalyzed Si─Me Bond Activation Enabling Alkyl Exchange at Silicon

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
A new type of Si─Me bond activation enabling catalytic alkyl exchange at Si was developed. It involves a P‐directing group and Pd─Lewis acid cooperation. It enables the conversion of Me3SiCl into silanols with three different organic substituents. ABSTRACT A novel mode of Si─Me bond activation has been unveiled through the cooperative action of a P ...

www.mdpi.org/ijms/ C- versus O-Arylation of an Enol-Lactone Using Potassium tertbutoxide

, 2014
: The use of potassium tert-butoxide as the base in arylation reactions of an enollactone with a series of benzyl halides was explored. Our work demonstrates that the ratio of C-arylation to O-arylation varies with the substitution pattern of the aryl ...

Scaffold Hopping Provides Liver X Receptor Agonist With Preference for the β Subtype

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
A scaffold hopping strategy was pursued to enhance the binding pocket engagement and β‐subtype selectivity of liver X receptor agonist 2. The resulting spirocyclic lead compound, (S)‐7, demonstrates superior potency, enhanced potency‐based selectivity for LXRβ, and improved microsomal stability over the existing scaffold.

Deprotonation and Alkylation of Weakly Acidic C(sp3)─H Bonds Through In Situ Generation of a Strong Hydride Base From 1,1,3,3‐Tetramethyldisiloxane and Potassium tert‐Butoxide

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Synthesis of S‐Arylthioxanthonium Trifluoromethanesulfonates From Thioxanthones and Diaryliodonium Salts by Copper(II) Catalysis and Application to Aryl–Heteroaryl Bond Formation by Direct LED Irradiation

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
A straightforward Cu(II)‐catalyzed synthesis of S‐arylthioxanthonium trifluoromethanesulfonates from readily available thioxanthones and diaryliodonium salts is described. A broad range of salts is obtained in moderate to good yields. It is further demonstrated that S‐arylthioxanthonium trifluoromethanesulfonates act as aryl radical precursors under ...
