A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

Asian Journal of Organic Chemistry, EarlyView.
This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Kinetically Enhanced Access to a Dynamic Polyester Platform via Sequence Selective Terpolymerisation of Elemental Sulphur

Angewandte Chemie, EarlyView.
A rare sequence‐selective terpolymerisation of elemental sulphur, aromatic thioanhydrides, and epoxides yields dynamic poly(ester‐alt‐Sx) polymers. Mechanistic insights reveal a lithium‐catalysed rate enhancement via ester coordination. The resulting polymers are thermally stable, backbone‐editable, and processable into degradable adhesives.

Synthesis of a Molecular Tweezer Based on Norbornadiene Framework: Unexpected Stereoselectivity

Asian Journal of Organic Chemistry, EarlyView.
A new type of Klarner's molecular tweezer was synthesized through annulation of an α‐amino ketone. Surprisingly, the reaction takes place stereoselectivity though the initial amino ketone is racemic. This tweezer comprises two near‐parallel flat aromatic rings as pincers, each bearing two methyl ester groups, and a pyrazine unit as the tether ...

Conformational Change in a Four‐Tetrad DNA G‐Quadruplex upon Intercalation of a Small‐Molecule Ligand PyDH2

Angewandte Chemie, EarlyView.
An exception or the rule? This work represents a second observation, and the first crystallographic evidence, of true intercalation of a small‐molecule ligand (here, bisquinolinium PyDH2) into an antiparallel G‐quadruplex (G4) DNA fold. Abstract G‐quadruplexes (G4s) are non‐canonical DNA structures implicated in a number of biological processes.
