Macrocyclic Hosts Featuring a Tetraphenylethene‐Embedded Skeleton: From Molecular Design and Photophysical Properties to Applications

Aggregate, EarlyView.
The orthogonal integration of tetraphenylethylene (TPE) and its derivatives into the frameworks of five conventional macrocyclic hosts has garnered significant attention in the field of macrocyclic chemistry. This minireview systematically categorizes TPE‐embedded macrocyclic hosts into three types: non‐, semi‐, and full‐TPE‐embedded skeleton based on ...

Applications of N─F─Based Reagents in the Synthesis of Organochalcogen Compounds

Asian Journal of Organic Chemistry, EarlyView.
Herein, we provide a comprehensive review of recent advances in synthetic strategies to access organochalcogen‐decorated compounds using N─F reagents as efficient oxidants for converting chalcogen–chalcogen bonds into electrophilic chalcogen‐based species.

Highly Stereoselective Gem‐Dimethylcyclopropanation of Allylic Alcohols Promoted by Alkylidene Titanocenes

Asian Journal of Organic Chemistry, EarlyView.
A novel methodology has been developed for the regio‐, chemo‐, and diastereoselective conversion of a broad scope of allylic alcohols into the corresponding gem‐dimethylcyclopropane derivatives. The cyclopropanation reaction proceeds under mild conditions, mediated through an alkylidene titanocene generated in situ from CpTi(IV)Cl3, Mg and 2,2 ...

Synthesis of Poly‐Substituted Imidazo[1,2‐a]Pyridines via a Double Annulation Strategy

Asian Journal of Organic Chemistry, EarlyView.
Herein, we report a novel and efficient synthetic strategy for the construction of poly‐substituted imidazo[1,2‐a]pyridines from the reaction of enaminonitriles with propargylamines via a domino conjugate substitution–nucleophilic addition‐cycloisomerization process.

Radical Ring‐Opening Reaction of Non‐Activated Oximes Catalyzed by Aldoxime Dehydratases

Angewandte Chemie, EarlyView.
A novel catalytic mode of aldoxime dehydratases for the abiotic radical ring‐opening reaction of cyclic ketoximes is reported. Aldoxime dehydratase from Nocardioides simplex was found to efficiently generate iminyl radicals from challenging “non‐activated” cycloketone oximes and to promote radical ring‐opening reactions to produce γ‐ and ε‐sulfinylated
