Mapping Dual-Base-Enabled Nickel-Catalyzed Aryl Amidations: Application in the Synthesis of 4-Quinolones

Ryan T. McGuire et al.

Summary: This article introduces a new efficient protocol for the C-N cross-coupling of amides and (pseudo)halide-substituted acetophenones. The reaction can be conducted at room temperature and employs nickel catalysts and organic amine bases. Stoichiometric experiments support a Ni-0/II pathway, and the combination of DBU/NaTFA enables room-temperature amide cross-couplings.

Skeletal Reconstruction of 3-Alkylidenepyrrolidines to Azepines Enabled by Pd-Catalyzed C-N Bond Cleavage

Licheng Wu et al.

Summary: In this study, a new Pd-catalyzed strategy was reported for the construction of azepines through C-N bond cleavage reactions, showing good functional group tolerance and 100% atom economy. The use of 3-alkylidenepyrrolidine as a precursor for zwitterionic salts and the in situ formation of an allyl-palladium intermediate were key factors for the successful cascade [5 + 2] cycloaddition.
