Palladium‐Catalyzed Dual Csp2─Csp3 Bond Formation: A Versatile Platform for the Synthesis of Benzo‐Fused Heterocycles

Advanced Science, EarlyView.
Pd(II)/Cu(I) co‐catalyzed dual Csp2─Csp3 bonds construction from unactivated alkenes and arylsulfonyl chlorides to access benzo‐fused heterocycles with high efficiency and chemoselectivity. Abstract Transition‐metal‐catalyzed transformations offer a powerful approach to rapidly synthesize complex benzo‐fused heterocycles, crucial for drug and material ...

Radical‐Polar Crossover Bicyclization Enables a Modular Synthesis of Saturated Bicyclic Amines

Advanced Science, EarlyView.
Herein, we report the successful realization of a radical‐polar crossover bicyclization reaction from easily available cyclopropylamines and substituted alkenes through photoredox catalysis. This approach introduces an innovative methodology for the de novo synthesis of a diverse collection of 4/5‐, 5/5‐, 6/5‐,7/5‐ and 5/6‐fused saturated bicyclic ...

Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...
