A Fullerene‐Based Selenosugar Ball

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 36, September 29, 2025.
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.

Recent Insights in Multi‐Target Drugs in Pharmacology and Medicinal Chemistry

open access: yesChemMedChem, Volume 20, Issue 18, September 25, 2025.
This review highlights the rationale behind multitarget drug design as a promising approach to address diseases with complex etiologies. By combining pharmacophore features from different single‐target drugs, multitarget compounds can interact with multiple biological targets simultaneously.

The aminoindanol core as a key scaffold in bifunctional organocatalysts

open access: yesBeilstein Journal of Organic Chemistry, 2016
The 1,2-aminoindanol scaffold has been found to be very efficient, enhancing the enantioselectivity when present in organocatalysts. This may be explained by its ability to induce a bifunctional activation of the substrates involved in the reaction. Thus,
