Alkinyltriazene in photochemischen metallfreien Doyle‐Kirmse‐Umlagerungen

open access: yesAngewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Es wird eine metall‐ und additivfreie photokatalytische Doyle‐Kirmse‐Reaktion von Alkinyltriazenen beschrieben, die über Cyancarbenzwischenstufen verläuft. Diese Strategie ermöglicht den effizienten Aufbau hochsubstituierter asymmetrischer Kohlenstoffzentren mit breitem Substratspektrum und liefert synthetisch wertvolle Nitrile.

Harmine Derivatives as Anticancer Agents Endowed With Potent and Selective Antileukemia Activity: Synthesis, Biological Evaluation, Proapoptotic and Genotoxic Activity

open access: yesArchiv der Pharmazie, Volume 359, Issue 2, February 2026.
We identified a novel N9‐substituted harmine analog, compound 6, that selectively suppresses leukemic cell growth, triggers DNA damage, and activates apoptosis while sparing healthy fibroblasts. This discovery highlights N9‐modified β‐carbolines as a powerful new class of selective antileukemic agents, bridging natural product chemistry with next ...

De Novo Design and Synthesis of Novel Benzoxazinone Derivatives Targeting Dihydroxyacid Dehydratase

open access: yesPlant Biotechnology Journal, Volume 24, Issue 2, Page 567-581, February 2026.
ABSTRACT Dihydroxyacid dehydratase (DHAD), a key enzyme in the branched‐chain amino acid (BCAA) synthesis pathway, is a promising herbicide target. Currently, no commercial herbicides target DHAD, and no inhibitors are in development. Structural analysis suggests that coordination with iron–sulfur clusters and hydrophobic interactions with Tyr215 and ...

Intra‐ and Intermolecular Glycosylation of d‐Idopyranosyl and 6‐Deoxy‐d‐ido‐heptopyranosyl Donors: Toward the Repeating Unit of Campylobacter jejuni HS:4c Capsular Polysaccharide

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...

Synthesis of 2‐(Quinoxalin‐2‐yl)acetamides and Their Preliminary Cytotoxic and Antibacterial Activity

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT Quinoxaline is an aza‐heterocycle found in some bioactive compounds. Thus, to enhance the pharmacological scope of this nucleus, we report a series of 19 acetamides decorated with a quinoxaline core. The synthesis involved the linkage of previously constructed bromoacetamides and hydroxyphenyl quinoxalines via an SN2 reaction. The first series
