ChemistryEurope, Volume 4, Issue 6, June 2026.Polycyclic intermediates enable stereocontrolled synthesis of densely functionalized cis‐1,3‐diamine and amino alcohol carbocycles and heterocycles via structural‐to‐functional complexity transformations from low‐complexity starting material. Cis‐1,3‐functionalized carbocycles and saturated heterocycles are ubiquitous motifs in natural products ...

Soft Ferroelectrics in One Dimension: Ferroelectric Columnar Liquid Crystals
ChemPlusChem, Volume 91, Issue 6, June 2026.Helical ferroelectric columnar liquid crystals (FCLCs) confine bistable axial polarization within individual columns. An electric field reversibly flips the macrodipole, enabling two nonvolatile states readable as “0” and “1.” This Cconcept highlights supramolecular locking and helical architectures that deliver genuine switching and long‐lived zero ...

Journal of Physical Organic Chemistry, Volume 39, Issue 6, June 2026.The dithiirane–thiosulfine equilibrium has been revisited by means of modern computational chemistry tools to shed light on whether stable thiosulfines might be isolated. ABSTRACT Thiosulfines as reactive S‐centered 1,3‐dipoles undergoing (3 + 2)‐cycloadditions are still of interest in the chemistry of sulfur‐rich heterocycles.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Synthesis and 1,3-Dipolar Cycloaddition Reactions of Chiral Maleimides
Molecules, 1997 New routes to the synthesis of various novel chiral maleimides are described. The oxabicyclic anhydride 2 readily available exo-Diels-Alder adduct of furan and maleic anhydride was used as a vehicle, which in turn reacted with hydrochlorides of amino ...
