Circularly Polarized Luminescence in Rotaxanes and Catenanes

ChemistryEurope, EarlyView.
This review highlights the chiral rotaxanes and catenanes possessing static or stimuli‐responsive circularly polarized luminescence (CPL) activity both in solution and in the solid state. It also discusses macromolecular and supramolecular CPL‐emissive materials derived from these mechanically interlocked molecules.

Palladium‐Catalyzed [3+2] Cycloadditions of Alkylidenecyclopropanes to Imines: A Direct Approach to Pyrrolidine Scaffolds

ChemistryEurope, EarlyView.
Pd‐catalyzed annulations of ACPs with different C=N partners in both inter‐ and intramolecular ways are described. The methods provide access to pyrrolidines and pyrrolidine‐fused polycyclic systems, featuring β‐exo‐methylene moieties. Preliminary enantioselective variant has been shown by using a chiral phosphoramidite ligand and DFT studies shed ...

Mechanochemical Enantiospecific Syntheses of Sulfonimidate Esters and Sulfonimidamides by Various S(VI) Exchange Reactions

ChemistryEurope, EarlyView.
Mechanochemical S(VI) exchange reactions enable the solvent‐free, enantiospecific synthesis of sulfonimidate esters and sulfonimidamides by substituting S(VI)F or S(VI)Cl with phenols and anilines. This further opens green chemistries to the field of asymmetric synthesis.

Fluorescent Probe for δ‐Cyclodextrin Enables Guest Encapsulation Studies via an Indicator Displacement Assay

ChemistryEurope, EarlyView.
A molecular probe that partially unfolds and exhibits fluorescence enhancement upon binding to δ‐cyclodextrin (δ‐CD) is presented. Its implementation in a fluorescence indicator displacement assay to test the binding of various guest to δ‐CD is demonstrated.
