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 ...

Redefining CHI3L1: Therapeutic Opportunities at the Crossroads of Immune Suppression and Disease Progression

Medicinal Research Reviews, Volume 46, Issue 6, Page 1897-1921, November 2026.
ABSTRACT Chitinase‐3‐like‐1 (CHI3L1, also known as YKL‐40) has been recognized as a biomarker of inflammation and tissue remodeling and has now emerged as a pseudoenzymatic immune checkpoint. Recent structural, immunological, and translational studies redefine it as an active regulator of immune suppression rather than a passive disease marker. Despite

Ruthenium‐Catalyzed Nitrile‐Acrylate Reductive Coupling by 2‐Propanol: Synthesis of Enantioenriched β‐Amino Esters

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
The first nitrile reductive couplings beyond stoichiometric metals or metalloids are described. Using a ruthenium catalyst derived from RuHCl(CO)(PPh3)3 and Cy‐BIPHEP, 2‐propanol‐mediated reductive coupling of phenyl acrylate with aromatic or aliphatic nitriles delivers α,β‐unsaturated β‐amino esters.

Chemoproteomic discovery of a brain‐penetrant, covalent NLRP3 inhibitor that binds a novel allosteric pocket

British Journal of Pharmacology, Volume 183, Issue 22, Page 6718-6734, November 2026.
NLRP3 is a promising inflammatory target, but existing inhibitors lack diversity and brain penetrance, and none are approved. Using chemoproteomics, we discovered a novel series that binds to Cys463 in a previously uncharacterized pocket. Compounds showed nanomolar potency, brain exposure, and in vivo suppression of IL‐1β, supporting neuroinflammatory ...

Efficient Synthesis of Acylsilanes Using Morpholine Amides

, 2016
A general synthesis of acylsilanes from the corresponding morpholine amides and silyllithium species is described. The use of morpholine amides is economical and prevents over-addition by the silyl nucleophile.

Synthesis, Antiparasitic Activity, and ADME Profile of Morpholinephenylbenzamides: A Pharmacological Study Against Chagas Disease and Visceral Leishmaniasis [PDF]

ChemMedChem
Hit‐to‐lead optimization of morpholinephenylbenzamides reveals key structure–activity relationships against Trypanosoma cruzi and Leishmania infantum. Potency, selectivity, and ADME properties are differentially improved across the series, identifying compounds 20, 24, and 16 as complementary templates for the future design of dual antiparasitic leads.

Practical One‐Pot Synthesis of Cyclic Conjugated Amides From Ketones

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclic conjugated amides from simple ketones: a one‐pot bromoform‐mediated homologation/amidation sequence provides direct access to 20 conjugated amides, including functionalized and linear examples, in up to 91% yield. Conjugated amides are valuable building blocks in organic synthesis; however, general access to cyclic conjugated amides remains ...
