Transition Metal‐Free Carboxylation of Aryl Boronates in Supercritical CO2

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Transition metal‐free carboxylation of aryl boronates catalyzed by ZnO is achieved by using supercritical CO2. Cage‐shaped cyclic trialkoxyboronates, which are both nucleophilic and soluble in supercritical CO2, undergo the carboxylation efficiently in supercritical CO2 at high pressure and temperature to give corresponding aromatic carboxylic acids ...

Hydrogen peroxide ‐ responsive aminoferrocene prodrugs

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
Aminoferrocene (AF)‐based prodrugs are activated in cancer cells through reactions with H₂O₂ and other reactive oxygen species (ROS), generating electron‐rich AF’s. These, in turn, induce the production of highly toxic O2·‐ and HO·, leading to cancer cell death.

A C3‐Symmetric Diphenylethylendiamine‐Based Catalyst in the Asymmetric Michael Addition of α,β‐Unsaturated Ketones with 4‐Hydroxycoumarin and 4‐Hydroxyquinolin‐2‐One

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Two C3‐symmetric organocatalysts with multiple amino groups are prepared and employed in the asymmetric addition of 4‐hydroxycoumarin and quinoline‐2‐one to unsaturated ketones. The all‐amino version of the catalyst induces the better stereoselectivity and provides the products in up to 95% yield.

Synthesis of Long‐Chain Dimethylalkyl Methyl Ethers, Important Components of the Epicuticular Wax of Spiders

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Long‐chain dimethyl‐branched aliphatic methyl ethers are key components of spiders’ epicuticular and web lipids. Evaluating different strategies for their synthesis, it is found that the late introduction of the methyl groups via alkynyl mesylate substitutions and hydrogenation gives faster and cleaner access to such target compounds compared to other ...

A Fullerene‐Based Selenosugar Ball

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A fullerene hexakis‐adduct decorated with 12 peripheral seleno‐d‐talitol moieties is synthesized efficiently with a Th‐symmetry from a hexakis‐adduct of [60]fullerene prepared by a cycloaddition reaction and subsequent copper‐catalyzed azide‐alkyne cycloaddition click chemistry.
