Strategic Functionalization of Benzylic C(sp3)H Bonds: Unlocking the Potential for Enantioselective δ‐Lactonization

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Recent advancements in bio‐inspired Mn‐catalyzed directed oxidations of carboxylic acids have provided promising pathways for the synthesis of a wide variety of chiral γ‐lactones. In our current study, however, we have established a catalytic route using 0.25 mol% of electron‐rich Mn‐catalyst Mn(dMMbpbp) that redirects the lactonization reaction to the

Does Aromaticity Drive Metal Cation Binding to Nanographenes? Insights Into Regioselectivity and Cation‐π$$ \pi $$ Bonding

open access: yesJournal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
Aromaticity of a ring by itself does not explain the binding energies of alkali and alkaline earth metal cations with nanographenes, but when combined with the Fukui function, it does. ABSTRACT Nanographenes, a subclass of polycyclic aromatic hydrocarbons (PAHs), have attracted significant interest due to their unique electronic properties and broad ...
