Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Supramolecular Polymerization and Morphological Transformation of Dynamic Helical Poly(Phenylacetylene)s via Chain‐End Host–Guest Interactions

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
A helical polymer whose chain ends are connected through pillar[5]arene‐based host–guest interactions translates molecular helicity into supramolecular morphology. Solvent‐triggered helicity inversion accompanied by changes in chain rigidity switches the supramolecular architecture between cyclic and rigid‐rod nanostructures.

Assembly and Properties of Donor/Acceptor–Functionalized 2,6‐Bisethynylpyridines; Investigations of Through‐Bond and Through‐Space Charge Transfer Behavior

Journal of Physical Organic Chemistry, Volume 39, Issue 10, October 2026.
Introduction of a cation to donor/acceptor‐functionalized 2,6‐bisethynylpyridines results in through‐space interaction of donor and acceptor units. The electronic effects of this organization are explored using 1H‐NMR and UV‐vis spectroscopies. ABSTRACT Introduction of Ag(I) cations to 2,6‐bisethynylpyridine units decorated with electron‐donating (N,N ...

Synthesis of Methylisoxazol‐5(4H)‐One Derivatives Using an ʟ‐Proline‐Functionalized‐MMT Catalyst: Molecular Docking and Cancer Cell Line Cytotoxicity Studies

ChemistrySelect, Volume 11, Issue 38, 13 October 2026.
An efficient and sustainable method for the synthesis of biologically relevant isoxazoles is developed using modified montmorillonite‐K10 (MMT) nanoclay as a heterogeneous catalyst. The catalyst exhibited good stability and reusability over five cycles, with minimal loss of activity (95%–88%). ABSTRACT Guided by green chemistry principles, an efficient
