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 ...

Enantioselective Access to Trifluoromethylated Spirocyclopropyl Heterocycles
Advanced Science, Volume 13, Issue 62, 9 November 2026.We report a rhodium‐catalyzed asymmetric [2+1] spirocyclopropanation of methylene azacycles with trifluoromethyl carbenes in situ derived from fluoroalkyl triftosylhydrazones. ABSTRACT Chiral spirocyclopropyl heterocycles have emerged as privileged three‐dimensional structural motifs in medicinal chemistry.

ChemBioChem, Volume 27, Issue 20, 28 October 2026.Lipid membranes are fundamental to all prokaryotic life. Besides acting as barrier, by orienting as hydrophobic bilayer, lipids are involved in a wide variety of other cellular processes. As a consequence, prokaryotic membranes are dynamic entities that switch their lipid composition as required; a process that requires tight interplay with the lipid ...

Stereochemical Control in the Matteson Reaction
Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Selective N‐Functionalization of Pyrazoles
European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...
