aminoalkyl-substituted quinones have been efficiently prepared through silver-catalyzed site-selective deconstruction and C–C bond transformation of unstrained N-acylated cyclic amines. This method enjoys mild reaction conditions, high selectivity, a broad scope of substrates, and a low catalytic loading of silver. This strategy can also be applied to the modification of peptides bearing cyclic amine residues.

with weakly coordinating groups normally requires a transient directing group or presynthesized nitrogen-based strong coordinating ligands. Herein, we report Pd(II)-catalyzed C(sp3)–H arylation and alkenylation of Weinreb amides. A commercially available, inexpensive sulfonic acid was employed to enhance the coordination of the catalyst with weak-coordinating substrates by increasing the electrophilicity
