Two‐Stage, Sequential Aryne Carboiodanation Enabled by Mesomeric Priming

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Two‐stage, sequential insertion of arynes into the carbon–iodine(III) bond of benziodoxole (BX) compounds is achieved by judicious choice of the BX/aryne pair in the first step, generating a mesomerically activated aryl‐BX primed for a second, discrete aryne insertion. This metal‐free strategy enables programed access to biaryl‐BXs and modular entry to

O2‐Mediated Cu‐Catalyzed Dehydrogenative Sulfilimination of Tyrosines and Bioactive Phenols

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
We report herein the mild O2‐mediated Cu‐catalyzed dehydrogenative sulfilimination of diverse bioactive phenols with simple sulfenamides. The bioconjugation of unmodified native peptides, in particular at their tyrosine units with the dehydrogenative phenochalcogenazination reaction, has attracted much attention lately due to potential click type ...

Catalytic Enantioselective Synthesis of Conformationally Stable C(sp2)−C(sp3) Naphthocoumarin Atropisomers

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
The enantioselective synthesis of naphthocoumarin adducts via a tandem organocatalytic 1,4‐addition/decarboxylation delivers excellent control over a newly forged stereocenter and yields configurationally stable synclinal atropisomers. The process features broad substrate scope and scalability, and its structural and mechanistic foundations are ...

An Organometallic [2]Catenane With Pt‒(di‐NHC)‒Pt Units: A Topology‐Driven Strategy for Enhanced Phosphorescence in Discrete Aggregates

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
The mechanically interlocked Borromean rings are stabilized by π···π stacking interactions while the [2]catenane is stabilized by solvophobic effects. While the π···π interactions in the Borromean rings lead to severe luminescence quenching, the solvophobically assembled [2]catenane effectively circumvents these interactions, simultaneously restricting

Design, Synthesis, and Structural Analysis of Binaphthyl‐Based Chiral Benzindenes

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
This work explores the synthetic endeavors in constructing the first‐of‐a‐kind axially chiral benz[f]indenes as potential chiral ligands. The overall synthetic pathway spans across 9 steps with 15.9% overall yield. Challenges in constructing modified analogs as well as metal complexes are discussed. Chiral benzindenes are an unexplored structural motif
