Charlotte Pommer: Resistance fighter and female pioneer of German anatomy

Anatomical Sciences Education, Volume 19, Issue 9, Page 1415-1429, September 2026.
Abstract This article examines the biography and unique case of Charlotte Pommer (1914–2004), the only anatomist documented to have left the field during the Nazi period after encountering the regime's victims on the dissection table. While she is known for her resistance activities, newly presented documentation reveals her role as the provisional ...

Synthesis, Physicochemical Properties, and Ion Recognition Ability of Azulene-Based Bis-(Thio)Semicarbazone

Molecules
Azulene-1,3-bis(semicarbazone), 1, and azulene-1,3-bis(thiosemicarbazone), 2, were synthesized by the acid-catalyzed condensation reactions of semicarbazide and thiosemicarbazide, respectively, with azulene-1,3-dicarboxaldehyde in stoichiometric amounts.

On the bromination of the dihydroazulene/vinylheptafulvene photo-/thermoswitch

Beilstein Journal of Organic Chemistry, 2012
Background: The dihydroazulene (DHA)/vinylheptafulvene (VHF) system (with two cyano groups at C1) functions as a photo-/thermoswitch. Direct ionic bromination of DHA has previously furnished a regioselective route to a 7,8-dibromide, which by elimination

Formation of Bicyclic Skeletons by Aerobic, Manganese‐Mediated Cyclization of β‐Oxoesters

European Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
Manganese(III) promotes aerobic radical cyclization reactions of β‐oxoesters with an ω‐alkenyl side chain at the β’‐position to give bicyclic products with a 1,4‐dicarbonyl structure. Bicyclic perhydro‐pentalene, ‐indene, and ‐azulene, as well as decaline skeletons were accessed by aerobic manganese(III)‐mediated radical cyclizations of cyclic β ...

Determination of the Physical and Chemical Properties and Volatile Aroma Components Distribution of Geographically Indicated Besni Grape Raisin

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
This study characterized the physical, chemical, and volatile aroma profiles of geographically indicated yellow and black Besni grapes harvested from the Besni and Gölbaşı districts of Adıyaman, Türkiye. The effects of on‐branch dehydration versus traditional direct sun drying were comprehensively evaluated.

Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...
