Chalcogen bond-guided conformational isomerization enables catalytic dynamic kinetic resolution of sulfoxides

Nature Communications, 2022
Conformational isomerization of organic molecules can be guided by noncovalent interactions. Here, the authors report the synthesis of chiral sulfoxides catalyzed by N-heterocyclic carbenes; intramolecular chalcogen bonding interactions are key for ...

Exploring Epigenetic Marks by Analysis of Noncovalent Interactions [PDF]

ChemBioChem, 2020
AbstractEpigenetic marks are modest chemical modifications on DNA and histone proteins that regulate the activation or silencing of genes through modulation of the intermolecular interactions between the DNA strands and the protein machinery. The process is complex and not always well understood.
