Antioxidant Activities of Pentacyclic Triterpenes From Melipona beecheii Propolis and Their Semisynthetic Derivatives

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
M. beecheii propolis contains eleven identified PTs, including germanicone and glutinol, reported for the first time in this material. Antioxidant assays reveal Fe(III)‐reducing activity at an effective concentrations lower than DPPH radical‐scavenging activity.

Diversification of the Avarane Skeleton Toward Spiroetherone A

ChemistryEurope, Volume 4, Issue 9, September 2026.
Molecular complexity and diversity were generated from the avarone skeleton, leading, among other transformations, to an oxaspiro[4.5]dienone via Wagner–Meerwein rearrangements, a popolohuanone E‐like dibenzofuran via a (3+2) dimerization, and a pentacyclic imidate via a tandem PIDA‐mediated alkene–phenol cyclization/Ritter reaction.

Layered π Systems Based on Ferrocenophanes

European Journal of Inorganic Chemistry, Volume 29, Issue 25, 1 September 2026.
Syntheses of a variety of ferrocenophanes and extensions of their π systems are reported. These are performed by Knoevenagel reactions and predominantly lead to syn diastereomers. Eight ferrocenophanes were crystallographically characterized. [1.1]Ferrocenophane was prepared by the literature method along with a small amount of [1.1.1.1]ferrocenophane,

Tunable Synthesis of Multi‐Responsive NH‐Containing Helical Nanographenes With a Chiroptical Switching Function

Angewandte Chemie, Volume 138, Issue 35, 24 August 2026.
The Scholl reaction of 1,3,6,8‐tetrakis(oligophenyl)‐appended carbazoles afforded stable NH‐containing helical nanographenes, which showed significant redshift and reversible on/off switching of CPL upon the addition of base and acid, respectively. Furthermore, excited‐state proton transfer occurred in dimethyl sulfoxide to generate anionic species ...

1,2‐Dihydroxyanthraquinone, 6,7‐Dihydroxyisobenzofuranone and 7,8‐Dihydroxyquinolinone Derivatives as Ligands for the Self‐Assembly of Hierarchically Formed Lithium‐Bridged Titanium(IV) Helicates

European Journal of Organic Chemistry, Volume 29, Issue 33, 1 September 2026.
Catechol‐based annulated aromatics with carbonyl units are ideal ligands for the formation of titanium(IV) containing lithium‐bridged hierarchical helicates. They allow for the first time the use of amide units to obtain the dimeric helicate‐type complexes.
