High Potential Isoindoline‐Based Nitroxides Posolytes for Aqueous Organic Redox Flow Batteries

open access: yesChemSusChem, Volume 19, Issue 3, February 2026.
A convenient metal‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of isoindoline‐based nitroxides as new posolytes for aqueous organic redox flow batteries. The cationic PPO exhibits a 220 mV higher oxidation potential than 4‐TMA‐TEMPO, 3 M solubility in 1 M NaCl, and a cell voltage of 1.56 V.

Divergent Total Synthesis of Denudatine Alkaloids Cochlearenine, Macrocentrine, Dictizine, 15‐Veratroyl‐17‐Acetyl‐19‐Oxodictizine, and the Proposed Structure of Acochlearine

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
An intramolecular Mannich reaction (A/B/E/F rings) and intermolecular Diels–Alder reactions (C/D rings) afforded a cage‐like hexacyclic core skeleton of denudatine alkaloids. Derivatization of the hexacyclic intermediate enabled the first asymmetric total syntheses of four denudatine alkaloids: (–)‐cochlearenine, (–)‐macrocentrine, (–)‐dictizine, and (–
