Synthesis and Characterization of Hemiindigo‐Based Glycoside and Glycomacrocycle

Chemistry – A European Journal, Volume 32, Issue 42, 12 November 2026.
Glycosyl hemiindigos: we have synthesized hemiindigo‐functionalized glycoside and glycomacrocycle which are photoswitchable under visible light irradiation with high photoconversion yield and fluorescence emission property in acetonitrile. The conformational constrained glycomacrocycle displayed more efficient photoisomerization.

Catalyst‐Controlled Divergent Strain‐Release Amination and Skeletal Remodeling of Bicyclo[1.1.0]Butanes

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.
Catalyst‐controlled nitrene transfer unlocks divergent reactivity of bicyclo[1.1.0]butanes. Rhodium catalysis promotes selective strain‐release amination to access cyclobutene and cyclobutane amino‐acid scaffolds, whereas visible‐light photocatalysis redirects nitrene reactivity toward double amination and skeletal remodeling, providing a complementary

Atroposelective Pd(0)‐Catalyzed Direct Intermolecular C─H Arylation of Thiazole N‐Oxides Provides Access to Heterobiaryls

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.
An enantioselective Pd(0)‐catalysed arylation at the C4‐position of thiazole N‐oxides directly forges the atropochiral heterobiaryl axis. A tailored point‐ and axially chiral monodentate phosphine ensures high reactivities along with a tight stereocontrol.

The Nature of Cell‐Penetrating Poly(disulfide)s

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.
The mode of action of cell‐penetrating poly(disulfide)s (CPDs) is elucidated to understand thiol‐mediated uptake (TMU) in general and guide future efforts to control cellular entry for chemicals delivery and pathogen defense. ABSTRACT Cell‐penetrating poly(disulfide)s (CPDs) are the most popular thiol‐mediated uptake (TMU) tools for delivering attached

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...
