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.

Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.

Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

Angewandte Chemie International Edition, Volume 65, Issue 43, 19 October 2026.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Synthesis and Fluorescence Profiling of Naphthylamine Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
N‐phenyl‐1‐naphthylamine (NPN) has been historically used as a probe to monitor gram‐negative bacterial outer membrane permeabilization, fluorescing only in hydrophobic environments. Herein, a 95‐membered naphthylamine library was synthesized to explore structure–fluorescence relationships, informed by density functional theory studies.
