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.

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 ...

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

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.

Angewandte Chemie, EarlyView.Described here is a LaNTMS mediated silylative conversion of primary amides to nitriles under neat reaction conditions. The reaction is highly efficient and selective under such solventless conditions, where all materials are commercially available, demonstrating the robustness and potential of lanthanide heteroatom catalysis.
